The melting of the polar ice caps has often been portrayed as a tsunami-inducing Armageddon in popular culture. In the 2004 disaster movie The Day After Tomorrow, the warming Gulf Stream and North Atlantic currents cause rapid polar melting. The result is a massive wall of ocean water that swamps New York City and beyond, killing millions in the process. And like the recent polar vortex in the Northern Hemisphere, freezing air then rushes in from the poles to spark another ice age.
The premise is obviously ridiculous. Or is it? Rapid glacial retreat in Alaska in 2015 did in fact trigger a huge landslide and a mega tsunami that was nearly 650 feet high when it hit shore. Few knew or cared because it luckily happened at the end of the Earth where no one was living.
Many of us might believe we won't be directly impacted by the breakup of trillions of tons of ice due to global heating. We figure that unless we live on a small island in the Pacific, or have a house on the beach, it's not our problem.
Or Is It?
While it's true that the glaciers, ice caps and ice sheets covering 10% of the Earth's land mass are mostly in the middle of nowhere, their rapid breakup has a cascading effect.
Consider how all the extra fresh water in the ocean is diluting salt levels. And how that messes with the balance of the Gulf Stream, one of the world's most important ocean currents. The result is climate extremes, especially tropical storms and hurricanes in places like the Gulf of Mexico, but also more frequent floods and droughts on both sides of the Atlantic. It's gonna suck for a lot of people.
To put this meltdown in context, the rate of ice sheet retreat has increased nearly 60% since the 1990s. That's a 28 trillion ton net loss of ice between 1994 and 2017. Antarctica's epic ice sheet, the world's largest, and the world's mountain glaciers have suffered half of this loss.
OK, That Sounds Like a Lot — But So What?
Again, it's the domino effect that's worrying. With temperatures rising twice as fast in the Arctic — the world's air conditioner — than anywhere else on the planet, the heat is not just melting ice. It's also weakening atmospheric air currents known as the jet stream. In other words, more bad news for the weather.
The polar vortexes that have been freezing Europe and North America in recent years are related to a weakened polar jet stream — a scenario that triggered the sudden ice age in The Day After Tomorrow.
The cold might be welcome as the planet heats up, but here's the thing: Arctic regions are heating up, too. Which means the ice that's supposed to be reflecting the sun's energy away from Earth isn't as much anymore, leaving the sea to absorb this heat.
No surprise then that in 2018 the winter ice sheet in the Bering Sea bordering Alaska was at its lowest levels in over 5,000 years.
Fish, sea bird, seal and polar bear habitats are also disappearing with the ice. Indigenous communities in the Arctic who once hunted in a thriving frozen ecosystem are being upended — their houses are also falling in the sea as the lack of ice causes the coast to erode.
Sure, it's an underpopulated part of the world. But consider also the rapid thaw of permafrost on the Siberian tundra. One of the world's biggest carbon sinks, the tundra is now releasing greenhouse gases like methane that were long trapped below the frost.
Some scientists have predicted that by century's end, 40% of permafrost regions will have disappeared, meaning they will no longer retain, but will also release carbon dioxide — and we're talking more than is already in the atmosphere right now. As global heating is turbocharged, bye bye to more ice.
Which leads us to the elephant in the room: rising sea levels.
How Bad Could Rising Sea Levels Get?
So let's start with the worst-case scenario — and remember the culprit here would be ice sheets and glaciers on land.
If the fast-retreating Antarctic ice sheet, the world's largest, completely melted, the world's oceans would rise by about 60 meters (about 200 feet). That would be Armageddon and London, Venice, Mumbai and New York would become aquariums.
Don't panic, though, this won't happen any time soon. But if emissions aren't sufficiently scaled back to mitigate climate change, some researchers reckon oceans will definitely rise by at least 2 meters by the end of the century. That's still enough to swamp the several hundred million people living below 5 meters above sea level. Another 350 million or so living higher up would have to relocate to escape regular coastal flooding.
Can't People Just Move?
Maybe, but that wouldn't be the end of it. The world's mountain glaciers, which number roughly 200,000, are melting much faster than they can accumulate these days. Problem is, though they only cover less than 0.5% of the Earth's landmass, these "water towers" provide fresh water to about a quarter of the world's population.
Glaciers also feed the rivers that irrigate the crops which hundreds of millions of people across Asia, South America and Europe depend on for their survival. So without them, many people will suffer from both thirst and hunger. Scientists say water tower retreat has put almost 2 billion people at risk of water scarcity.
Right now, cities like Santiago in Chile are watching a big part of their drinking water supply literally dry up as glaciers in the nearby Andes retreat. Meanwhile, the European Alps that supply so much fresh water across the region have shrunk by about half since 1900 and will be almost ice free by century's end if nothing more is done to curb warming.
OK, Is There Anything That We Can Do?
Like global heating in general, the best way to mitigate the meltdown is to stop polluting the atmosphere with global warming-inducing carbon.
Of course, the process can't be reversed overnight. Even if people across the world stopped using fossil fuels tomorrow, one-third of the world's remaining glaciers would still disappear.
So to save some amount of precious polar and glacial ice, we need to avoid the temperature rise of over 3 degrees Celsius (5.4 Fahrenheit) that the UN says is inevitable if governments don't step up climate targets. If the world can decarbonize by 2050, it might be possible to preserve around one-third of the current glacial mass by century's end. That would take both government action and a radical commitment to reduce our individual carbon footprint.
The future remains uncertain. But it's likely that if melting isn't slowed real soon, disaster movie scenarios might not look so ridiculous to future generations.

In 1963, inside a covert U.S. military base in northern Greenland, a team of scientists began drilling down through the Greenland ice sheet. Piece by piece, they extracted an ice core 4 inches across and nearly a mile long. At the very end, they pulled up something else – 12 feet of frozen soil.
The ice told a story of Earth's climate history. The frozen soil was examined, set aside and then forgotten.
Half a century later, scientists rediscovered that soil in a Danish freezer. It is now revealing its secrets.
Using lab techniques unimaginable in the 1960s when the core was drilled, we and an international team of fellow scientists were able to show that Greenland's massive ice sheet had melted to the ground there within the past million years. Radiocarbon dating shows that it would have happened more than 50,000 years ago. It most likely happened during times when the climate was warm and sea level was high, possibly 400,000 years ago.
And there was more. As we explored the soil under a microscope, we were stunned to discover the remnants of a tundra ecosystem – twigs, leaves and moss. We were looking at northern Greenland as it existed the last time the region was ice-free. Our peer-reviewed study was published on March 15 in Proceedings of the National Academy of Sciences.

With no ice sheet, sunlight would have warmed the soil enough for tundra vegetation to cover the landscape. The oceans around the globe would have been more than 10 feet higher, and maybe even 20 feet. The land on which Boston, London and Shanghai sit today would have been under the ocean waves.
All of this happened before humans began warming Earth's climate. The atmosphere at that time contained far less carbon dioxide than it does today, and it wasn't rising as quickly. The ice core and the soil below are something of a Rosetta Stone for understanding how durable the Greenland ice sheet has been during past warm periods – and how quickly it might melt again as the climate heats up.
Secret Military Bases and Danish Freezers
The story of the ice core begins during the Cold War with a military mission dubbed Project Iceworm. Starting around 1959, the U.S. Army hauled hundreds of soldiers, heavy equipment and even a nuclear reactor across the ice sheet in northwest Greenland and dug a base of tunnels inside the ice. They called it Camp Century.
It was part of a secret plan to hide nuclear weapons from the Soviets. The public knew it as an Arctic research laboratory. Walter Cronkite even paid a visit and filed a report.

Camp Century didn't last long. The snow and ice began slowly crushing the buildings inside the tunnels below, forcing the military to abandon it in 1966. During its short life, however, scientists were able to extract the ice core and begin analyzing Greenland's climate history. As ice builds up year by year, it captures layers of volcanic ash and changes in precipitation over time, and it traps air bubbles that reveal the past composition of the atmosphere.
One of the original scientists, glaciologist Chester Langway, kept the core and soil samples frozen at the University at Buffalo for years, then he shipped them to a Danish archive in the 1990s, where the soil was soon forgotten.
A few years ago, our Danish colleagues found the soil samples in a box of glass cookie jars with faded labels: "Camp Century Sub-Ice."

A Surprise Under the Microscope
On a hot July day in 2019, two samples of soil arrived at our lab at the University of Vermont frozen solid. We began the painstaking process of splitting the precious few ounces of frozen mud and sand for different analyses.
First, we photographed the layering in the soil before it was lost forever. Then we chiseled off small bits to examine under the microscope. We melted the rest and saved the ancient water.
Then came the biggest surprise. While we were washing the soil, we spotted something floating in the rinse water. Paul grabbed a pipette and some filter paper, Drew grabbed tweezers and turned on the microscope. We were absolutely stunned as we looked down the eyepiece.
Staring back at us were leaves, twigs and mosses. This wasn't just soil. This was an ancient ecosystem perfectly preserved in Greenland's natural deep freeze.
Dating Million-Year-Old Moss
How old were these plants?
Over the last million years, Earth's climate was punctuated by relatively short warm periods, typically lasting about 10,000 years, called interglacials, when there was less ice at the poles and sea level was higher. The Greenland ice sheet survived through all of human history during the Holocene, the present interglacial period of the last 12,000 years, and most of the interglacials in the last million years.
But our research shows that at least one of these interglacial periods was warm enough for a long enough period of time to melt large portions of the Greenland ice sheet, allowing a tundra ecosystem to emerge in northwestern Greenland.
We used two techniques to determine the age of the soil and the plants. First, we used clean room chemistry and a particle accelerator to count atoms that form in rocks and sediment when exposed to natural radiation that bombards Earth. Then, a colleague used an ultra-sensitive method for measuring light emitted from grains of sand to determine the last time they were exposed to sunlight.

The million-year time frame is important. Previous work on another ice core, GISP2, extracted from central Greenland in the 1990s, showed that the ice had also been absent there within the last million years, perhaps about 400,000 years ago.
Losing the Greenland ice sheet would be catastrophic to humanity today. The melted ice would raise sea level by more than 20 feet. That would redraw coastlines worldwide.
About 40% of the global population lives within 60 miles of a coast, and 600 million people live within 30 feet of sea level. If warming continues, ice melt from Greenland and Antarctica will pour more water into the oceans. Communities will be forced to relocate, climate refugees will become more common, and costly infrastructure will be abandoned. Already, sea level rise has amplified flooding from coastal storms, causing hundreds of billions of dollars of damage every year.

The story of Camp Century spans two critical moments in modern history. An Arctic military base built in response to the existential threat of nuclear war inadvertently led us to discover another threat from ice cores – the threat of sea level rise from human-caused climate change. Now, its legacy is helping scientists understand how Earth responds to a changing climate.

CBD oil is one dietary supplement where "organic" labels are very important to consumers. Learn about the importance of organic hemp oil, why it's better for the environment, and which CBD companies actually make trustworthy products with sustainable farming processes. Use our curated list to find the best organic CBD oil that's better for you and the environment.
What is Organic CBD Oil?
CBD stands for cannabidiol, and it's one of the hundreds of cannabinoids found within cannabis sativa plants. This plant compound is believed to have many potential health and wellness benefits, including support for anxiety, stress, sleep, and chronic pain.
Since CBD is extracted from industrial hemp, it contains only trace amounts of THC (the psychoactive component in cannabis plants). Instead, the effects of CBD are much more subtle and promote a general sense of calm and relaxation in most users.
The most important (and prominent) certification for organic products comes from the United States Department of Agriculture (USDA). What exactly does this certification entail? Essentially, a label indicating that a product is "USDA Organic" or "Certified Organic" means that at least 95% of the ingredients are obtained from organic sources.
For hemp to be considered organic by the USDA, it must be grown without the use of industrial solvents, irradiation, genetic engineering (GMOs), synthetic pesticides, or chemical fertilizer. Instead, farmers rely on natural substances and mechanical, physical, or biologically based farming techniques to cultivate healthy and organic crops.
Choosing an organic CBD oil without additives is important because it indicates that a product is both safe to use and better for the environment. CBD extracted from an organic hemp plant is more likely to be free from pesticides, heavy metals, and other harmful toxins. This allows you to enjoy the benefits of the plant extract without worrying about any additional and unwanted compounds. Organic CBD is also a better choice for the environment, as it is grown using more sustainable farming practices that help preserve and protect land and water resources.

How We Chose the Best Organic CBD Oils
To create our list of the best organic CBD oil, we compared brands and products on a number of different criteria. These included:
- Hemp Source - We chose brands that use organic hemp grown in the U.S. and that follow natural and organic farming practices.
- Natural Ingredients - Each of the products on our list were examined to see if they used organic and natural ingredients for things like flavoring and carrier oils.
- Strengths - We looked for organic CBD oils that provide different concentrations of CBD to choose from, depending on your needs.
- Lab Testing - All of the CBD products we recommend must undergo independent third-party lab testing and provide access to those results.
- Certifications - In addition to USDA organic certification, we also looked for seals from the U.S. Hemp Authority, U.S. Hemp Roundtable, B-Corp, and other industry standards.
A note about USDA organic certification: before the passage of the 2018 Farm Bill, no hemp-derived products could be dubbed as "certified organic" as the hemp plant and its extracts were still categorized as a Schedule I Controlled Substance.
Due to the fact that industrial hemp has only recently become an agricultural crop, very few CBD oils are USDA certified organic. Many CBD products contain hemp extracts from plants that were grown organically, but may not be federally certified yet. Where necessary, we researched each brand's growing and harvesting practices to determine if they follow organic and natural cultivation methods, even if they are not fully certified by the USDA.

The Research on Organic Hemp Oil
What does the science say about organic CBD oil? There is evidence that CBD can help for certain conditions, specifically things like anxiety, sleeplessness, and pain. In fact, CBD taken for anxiety may have fewer side effects than certain prescription anxiety medications. However, as hemp and CBD remain unregulated by the Food and Drug Administration, it is vitally important to do your research and choose high-quality and safe products.
Using organic CBD oil is an easy way to help ensure that you can enjoy the health and wellness benefits of CBD while avoiding any potential toxins or synthetic chemicals.
Hemp is a unique plant, not only for its rich cannabinoid content, but because it is a bioaccumulator, and has the ability to absorb a wide variety of components in the soil. This trait means that hemp can help the environment through the remediation of green spaces, but it poses great risks when it comes to the creation of CBD products derived from hemp.
Because hemp has a high capacity for compound uptake, this means that the plants can retain harmful chemicals like pesticides, heavy metals, and other residual solvents. This is especially true when it comes to synthetic chemicals that are more toxic to humans, and difficult to remove once they have been absorbed by the hemp plant.
Organic farming practices help reduce the risk of hemp crops absorbing harsh chemicals that may later end up in CBD oil after extraction. When you're taking CBD as a wellness supplement to help alleviate your symptoms or improve your overall well-being, the last thing you want is to ingest compounds that might negatively outweigh the benefits of CBD. This is an important reason to look for third party lab test results when shopping for CBD products since these certificates of analysis can show the full cannabinoid and terpene profile of a hemp extract, as well as test results that search for the presence of any residual solvents. If you choose a non-organic CBD oil, you will need to rely even more on the independent lab test results to make sure the product is safe.
In addition to creating a better end product, organic farming practices are also better for the environment. Sustainable and organic farming methods may reduce pollution, conserve water, reduce soil erosion, increase soil fertility, and use less energy. The use of natural pest deterrents as opposed to chemical pesticides is also better for nearby animal populations and ecosystems.
How to Choose CBD Oil for You
When shopping for an organic CBD oil, you can look for certain key ingredients and certifications to find the best options. Here are some tips on how to compare and choose the right organic CBD oil.
What to Look For
Start by looking for the following pieces of information when considering any CBD product:
Make sure you know if the product uses full spectrum, broad spectrum, or CBD isolate hemp extract. Full spectrum CBD contains all of the natural phytocannabinoids, terpenes, and fatty acids found in the hemp plant, including THC. This may produce a fuller result through the entourage effect. However, if you are concerned about THC, or are subject to a drug test, broad spectrum and CBD isolate products offer a great alternative.
Always check to see how much CBD the product contains. This is measured in milligrams per container and milligrams per serving. A single serving for CBD oil is typically 1 mL, and most brands offer recommendations for measuring and dosages.
The source of the hemp used to extract CBD is vitally important. We recommend choosing brands that use organic and naturally-grown hemp raised in the U.S.A. for safety standards. This is the quickest way to ensure that the CBD itself is pure and free from pesticides or other harmful compounds.
We only recommend CBD oils and products that are subject to independent third-party lab testing. This is a crucial step that verifies both the safety and purity of the oil as well as the potency of the CBD per serving. Look for brands that give you easy access to the lab test results for every product they sell.
How to Read Labels
Here are the primary things to look for when reading the label on a CBD oil or product:
- Type of CBD - The label should clearly state whether the product contains full spectrum, broad spectrum, or CBD isolate hemp extract. If it is broad spectrum or isolate, look for a mark that tells you it is "THC-free."
- Certifications - Certain brands will include seals of approval to show that their product is USDA-certified organic, non-GMO, made in the U.S.A., or U.S. Hemp Authority certified.
- Other Ingredients - Check the ingredients list for anything in the product besides the CBD extract. This typically includes a carrier oil, like MCT or hemp seed oil, but can also include flavorings or botanicals. Make sure they are all-natural and that you are not allergic to any of them.
- Test Results - Most brands include a QR code on the packaging or the label of their CBD product that you can scan to view the third-party test results. This is a key way to know if a brand is trustworthy and whether their CBD is safe to use.
How to Use
Organic CBD oil is used just like any other CBD oil tincture, and is primarily ingested using a dropper to measure out the correct dose. Many brands recommend that you take the CBD oil sublingually by placing the CBD tincture under your tongue for 30 seconds or so before swallowing to aid in absorption. You can also add CBD to food and beverages, though some argue that this lessens the effect.
Some of the most common wellness advantages that people seek from organic CBD include:
- Chronic pain relief
- Anti-anxiety effects
- Better sleep
- Improvements in mood
- Internal balance and regulation
If you take organic CBD for help with sleep, take the recommended amount about an hour before bed. If you are taking it for anxiety, you can take one dose in the morning and another in the evening to help promote a sense of calm throughout the day. As with all CBD products, we recommend that you start with a lower dose and gradually increase it to achieve the desired effects rather than starting with a high dose.
Safety and Side Effects
CBD, while generally well-tolerated and safe for adults, can produce side effects in certain people. These are generally very mild, but can include things like nausea, diarrhea, fatigue, and irritability. CBD may also interact with certain prescription drugs, especially blood thinners and statins. If you take a prescription medication, be sure to consult with your doctor before starting CBD.
CBD has the potential to help with a number of health and wellness concerns, especially anxiety, insomnia, and chronic pain. To make sure that you choose the right option, go with the best organic CBD oil without additives from a brand you trust. Use our list to help you get started and find the natural relief you need.

A new study is shedding light on just how much ice could be lost around Antarctica if the international community fails to urgently rein in planet-heating emissions, bolstering arguments for bolder climate policies.
The study, published Thursday in the journal Geophysical Research Letters, found that over a third of the area of all Antarctic ice shelves — including 67% of area on the Antarctic Peninsula — could be at risk of collapsing if global temperatures soar to 4°C above pre-industrial levels.
An ice shelf, as NASA explains, "is a thick, floating slab of ice that forms where a glacier or ice flows down a coastline." They are found only in Antarctica, Greenland, Canada, and the Russian Arctic—and play a key role in limiting sea level rise.
"Ice shelves are important buffers preventing glaciers on land from flowing freely into the ocean and contributing to sea level rise," explained Ella Gilbert, the study's lead author, in a statement. "When they collapse, it's like a giant cork being removed from a bottle, allowing unimaginable amounts of water from glaciers to pour into the sea."
"We know that when melted ice accumulates on the surface of ice shelves, it can make them fracture and collapse spectacularly," added Gilbert, a research scientist at the University of Reading. "Previous research has given us the bigger picture in terms of predicting Antarctic ice shelf decline, but our new study uses the latest modelling techniques to fill in the finer detail and provide more precise projections."
Check out my piece for @ConversationUK on how & why #Antarctica's #IceShelves are at risk as global #temperatures r… https://t.co/YCMzgfliiR— Dr Ella Gilbert (@Dr Ella Gilbert)1617975049.0
Gilbert and co-author Christoph Kittel of Belgium's University of Liège conclude that limiting global temperature rise to 2°C rather than 4°C would cut the area at risk in half.
"At 1.5°C, just 14% of Antarctica's ice shelf area would be at risk," Gilbert noted in The Conversation.
While the 2015 Paris climate agreement aims to keep temperature rise "well below" 2°C, with a more ambitious 1.5°C target, current emissions reduction plans are dramatically out of line with both goals, according to a United Nations analysis.
Gilbert said Thursday that the findings of their new study "highlight the importance of limiting global temperature increases as set out in the Paris agreement if we are to avoid the worst consequences of climate change, including sea level rise."
"If temperatures continue to rise at current rates," she said, "we may lose more Antarctic ice shelves in the coming decades."
The researchers warn that Larsen C—the largest remaining ice shelf on the Antarctic peninsula—as well as the Shackleton, Pine Island, and Wilkins ice shelves are most at risk under 4°C of warming because of their geography and runoff predictions.
"Limiting warming will not just be good for Antarctica—preserving ice shelves means less global sea level rise, and that's good for us all," Gilbert added.
All the more reason we need to push our leaders towards a quick end to the use of all fossil fuels! https://t.co/yrNUgjbkYG— Food & Water Watch (@Food & Water Watch)1617915642.0
Low-lying coastal areas such as small island nations of Vanuatu and Tuvalu in the South Pacific Ocean face the greatest risk from sea level rise, Gilbert told CNN.
"However, coastal areas all over the world would be vulnerable," she warned, "and countries with fewer resources available to mitigate and adapt to sea level rise will see worse consequences."
Research published in February examining projections from the Fifth Assessment Report of the U.N. Intergovernmental Panel on Climate Change as well as the body's Special Report on the Ocean and Cryosphere in a Changing Climate found that sea level rise forecasts for this century "are on the money when tested against satellite and tide-gauge observations."
A co-author of that study, John Church of the Climate Change Research Center at the University of New South Wales, said at the time that "if we continue with large ongoing emissions as we are at present, we will commit the world to meters of sea level rise over coming centuries."
Parties to the Paris agreement are in the process of updating their emissions reduction commitments—called nationally determined contributions—ahead of November's United Nations climate summit, known as COP26.

What really makes this reporter's stomach churn thinking about climate change? Thawing permafrost. A scenario where it all melts, releasing copious amounts of CO2 and methane (it holds twice as much carbon as the atmosphere holds right now), and there's no going back.
But what's at the top of the list of concerns for those who study how climate change is unfolding – on ice sheets and urban street corners, in oceans and farm fields – the climate scientists themselves?
DW asked a dozen experts spanning climatology, entomology, oceanography and yes, permafrost research, what keeps them up at night when it comes to the climate.
The Greatest Unknown – People
Nana Ama Browne Klutse studies changing weather with climate models at the University of Ghana. While she says tipping points like permafrost thaw worry her, she also worries how individuals will handle changing climates.
"What can you do as an individual to avoid the impact of climate change?" she asked. "We need government policies for resilience, building of community, city resilience. Then we need that global action."
Climate scientist Ruth Mottram studies the Greenland and Antarctic ice sheets and sea level rise for the Danish Meteorological Institute, but it's not the science that worries her.
"I'm less concerned that there are unknown processes going on that we don't understand, and there could potentially be some unforeseen catastrophe on the way," she said. "We know what a lot of the impacts are going to be. I think what keeps me awake at night in a metaphorical sense is really the interaction between the physical system and how human societies are going to handle it."
Giving the example of sea level, she says we will see a meter rise this century — in our lifetimes or that of our children — and will have to make tough decisions about our coastal cities. But she says it won't end there.
"I think that human societies have not really grasped what that means and that adaptation to sea level rise is going to be a long process and we are going to be doing it for hundreds of years," said Mottram, suggesting that we start thinking in terms of the lifetimes of cities (hundreds of years) rather than just human lifetimes.
Protecting the Vulnerable
Vladimir Romanovsky, a professor of geophysics at the University of Alaska Fairbanks' Permafrost Laboratory, said that while he thinks about how what happens in the Arctic will affect the rest of the world, his concerns are much more local.
"We should remember that there are still some people living in the Arctic," he said. Around 4 million people in fact who would have to deal with the real-life consequences of solid ground thawing beneath their feet and houses. "Changes in these local or regional kind of climates and environments, they impact these people and some of these impacts could be very severe."
Closer to the planet's other pole, Carolina Vera fears that existing inequalities will only be exacerbated by climate change.
"Climate change is already impacting the most vulnerable sectors of our planet," said Vera, who studies climate variability as a principal researcher for the National Council of Science of Argentina, a professor at the University of Buenos Aires and chief of staff for Argentina's Ministry of Science and Technology. Her work has led her to incorporate local knowledge and data collection into studies, involving communities that are balancing the problems of deforestation with their need to farm.
Heat and New Extremes
Perhaps not surprisingly, global heating is a key concern for many researchers, like Dim Coumou, who studies extreme weather at Vrije Universiteit Amsterdam.
Of most concern to him are heat and humidity extremes in the tropics – especially highly populated parts like West Africa, Pakistan and India – which will make it unbearable to be outside. When cooling down by sweating is no longer possible, people can't work outside and therefore can't grow food. The likely result being mass migration.
But it's not just the tropics.
Closely related to heat is the increase in extreme weather brought on by a warming climate. Coumou and his colleagues' research shows how changes to the jet stream will lead to more extreme weather in Europe, including floods and droughts.
This increase in extreme weather is climate scientist Abubakr Salih Babiker's biggest climate concern.
"A warmer atmosphere can hold more water in it and when it rains, it rains heavily leading to floods. A warmer ocean can lead to stronger tropical cyclones," said Babiker, who works for the East African Climate Center ICPAC in Nairobi. He explained that cyclones gain more energy from warmer water.
"We have seen evidence of all these events," he said. "The strongest tropical cyclones to impact the Arabian Peninsula, Somalia, and Mozambique occurred in the past 20 years!"
Science for Solutions
Pests, drought and flooding are on Esther Ngumbi's mind too.
An entomologist and professor of African American studies at the University of Illinois at Urbana-Champaign, she said that what keeps her up at night is the thought: "How can my science truly help?"
Ngumbi's work on pest and drought-resistant crops is driven by her concerns for vulnerable farmers who live in countries lacking social safety nets, where one season of crop devastation due to insects can mean going hungry and being unable to pay for their children's education.
"That truly makes me wake up every day and go to the lab to understand how my research can contribute to solutions that we need," she said.
Natasha Picone – an urban climatologist at the National University of Central Buenos Aires – says it's the solutions that occupy her thoughts too.
"With the pandemic, I realized that we are not doing enough for changing our cities to be more livable," she said. Her research informs urban planners about phenomena such as the urban heat island effect, air pollution and urban run-off that can lead to flooding. "If we don't change the path now, it will be really difficult to go back."
Weighing on the mind of oceanographer Renata Hanae Nagai at the University of Parana in Brazil is her four-year-old nephew and what his life will look like in a warmer world, but he also gives her hope. During a recent trip to the beach to watch nesting turtles, he warned others to leave the turtles alone.
She sees this same care in her students – learning about problems and coming up with solutions.
"People are the solution," she said. "We try, even under the hardest conditions."
'Scientists are Humans' Too
"For me, that's like morally totally unacceptable what they do – they lie," said the climate physicist from Maynooth University in Ireland, reflecting on encountering such people at public talks. "I mean, you can't argue with climate."
But this only pushes Caesar to better communicate what the science shows.
They Worry About Us
A common thread of this (rather unscientific) survey is that while we laypeople might be worrying about what the science says, climate scientists are often worrying about us.
"Scientists always think about what are the results of their studies, how are they important for, you know, for usual people, for normal people," the permafrost scientist told me. While doing his research, Romanovsky said he's always thinking about "how this could be used to make life of people easier or more predictable."

My journey to becoming an activist began in late 2018. During a trip to California to visit family, the Camp Fire broke out. At the time, it was the most devastating and destructive wildfire in California history. Thousands of acres and structures burned, and many lives were lost. Since then, California's wildfires have accelerated: This past year, we saw the first-ever "gigafire," and by the end of 2020, more than four million acres had burned.
After experiencing California's wildfires, I researched the connection between wildfires and climate change. Even though I was only 13 at the time, I realized I needed to do everything in my power to advocate for our planet and ensure that we have a safe and habitable Earth for not only my generation's future, but for future generations. Every day, our planet is increasing its calls for our help. Our ice caps are melting; sea levels are rising; heatwaves and droughts are increasing. We're seeing more frequent wildfires, hurricanes, tornadoes, and other extreme weather events. Climate change is happening right now, and people all over the world are losing their livelihoods — and even their lives — as a result of the growing number of climate-fueled disasters.
My activism started with the youth climate strike movement, which began when Greta Thunberg started striking in front of the Swedish Parliament in 2018. However, I want to acknowledge that young people, especially youth of color, have been protesting and demanding action for the planet for decades. I'm honored to follow in the footsteps of all the youth activists who paved the way for my activism and for the phenomenal growth of the youth climate movement that we have seen since 2018.
My experiences in the youth climate movement have allowed me to see that one of the greatest barriers we have to urgent climate action is education. Because of the lack of climate education around the world, I founded Earth Uprising International to help young people educate one another on the climate crisis, which ultimately has the effect of empowering young people to take direct action for their futures.
The primary mission of Earth Uprising International is increased climate and civics education for youth. Climate literacy and environmental education are the first steps to mobilizing our generations. By adding climate literacy to curricula worldwide, governments can ensure young people leave school with the skills and environmental knowledge needed to be engaged citizens in their communities. A climate-educated and environmentally literate global public is more likely to take part in the green jobs revolution, make more sustainable consumer choices, and hold world leaders accountable for their climate action commitments. Youth who have been educated about the climate crisis will lead the way in adaptation, mitigation, and solution making. Youth will be the ones who will protect democracy and freedom, advocate for climate and environmental migrants, and create the political will necessary to address climate change at the scale of the crisis.
So this year, for Earth Week, I am thrilled to be organizing a global youth climate summit called "Youth Speaks: Our Message to World Leaders," on April 20. Together, in collaboration with EARTHDAY.ORG and hundreds of youth climate activists around the world, the summit will address our main issues of concern, including climate literacy, biodiversity protection, sustainable agriculture, the creation of green jobs, civic skill training, environmental justice, environmental migration and borders, the protection of democracy and free speech, governmental policy making, and political will.
From this summit, youth climate activists from all over the world will be creating a concise list of demands that we want addressed at President Biden's World Leaders Summit, occurring on Earth Day, April 22. We believe that youth must inform and inspire these critical conversations about climate change that will impact all of us!
For more information about our global youth climate summit, "Youth Speaks: Our Message to World Leaders," go to www.EarthUprising.org/YouthSpeaks2021. There, you will find information about how to participate in our summit as well as be kept up to date on the latest agenda, participants, and follow along as we develop our demands and platform.
The youth will continue to make noise and necessary trouble. There is so much left to be done.

The Atlantic Meridional Overturning Circulation (AMOC) helps move heat from the tropics to the Northern Hemisphere, and is one of the reasons why Europe has relatively mild winters, Science Alert explained. However, the current has begun slowing down in recent years, and scientists want to know what it would take for the current to stop. A study published in Proceedings of the National Academy of Sciences Monday calculates that this moment could come sooner than expected.
"It is worrying news. Because if this is true, it reduces our safe operating space," Johannes Lohmann of the Niels Bohr Institute at the University of Copenhagen and study co-author said in a press release.
Essentially, the new findings come down to timing. The AMOC is threatened by increasing freshwater into the North Atlantic as the Greenland ice sheet melts. A certain amount of freshwater will cause the current to stop. But Lohmann wanted to test what would happen if that water were added quickly instead of gradually.
"These tipping points have been shown previously in climate models, where meltwater is very slowly introduced into the ocean," Lohmann told Gizmodo. "In reality, increases in meltwater from Greenland are accelerating and cannot be considered slow."
So researchers used an ocean model called Veros to calculate when the current would stop if freshwater were gradually added, the press release explained. Researchers then added freshwater at increased rates and found that quickly added freshwater would stop currents before reaching the initial freshwater threshold.
This has serious implications for the AMOC current itself. If it were to completely halt, tropical monsoon patterns would shift, rainfall in the Northern Hemisphere would decrease and the North Atlantic would get stormier. It also raises concerns about other climate tipping points, such as polar ice sheets collapsing or the Amazon rainforest drying out. If the AMOC can stop before the previously calculated tipping point is reached, is the same true for other systems?
"The results show that the safe operating space of elements of the Earth system with respect to future emissions might be smaller than previously thought," the study authors wrote.
However, outside scientists urged caution. Dave Sutherland, an associate professor in Earth sciences at the University of Oregon, told Gizmodo that the findings were important and timely, but that the models did not take all details into account, such as the location of the meltwater entering the ocean from Greenland.
Lohmann agreed that more testing is needed, but also pressed the urgency of climate action.
"Due to the potentially increased risk of abrupt climate change in parts of the Earth system that we show in our research, it is important that policymakers keep pushing for ambitious short- and mid-term climate targets to slow down the pace of climate change, especially in vulnerable places like the Arctic," Lohmann told Gizmodo.
Earth's ice is melting 57 percent faster than in the 1990s and the world has lost more than 28 trillion tons of ice since 1994, research published Monday in The Cryosphere shows.
"It was a surprise to see such a large increase in just 30 years," said Thomas Slater, a study co-author. There have been huge efforts to study ice loss research in individual regions of the world, allowing the researchers to combine data to assess ice loss worldwide. Their findings show that Arctic ice is disappearing the fastest, with 7.6 trillion tons melting between 1994 to 2017. The report also found land ice melt alone contributed to a global average sea level rise of 3.5 centimeters. However, land ice is only a small portion of the world's ice. Sea ice shelves, which float on water, are disappearing quickly. If they collapse, the land ice (glaciers) some sea ice shelves hold in place would be released and could accelerate sea level rise for centuries.
As reported by The Guardian:
The greatest quantities of ice were lost from floating ice in the polar regions, raising the risk of a feedback mechanism known as albedo loss. White ice reflects solar radiation back into space – the albedo effect – but when floating sea ice melts it uncovers dark water which absorbs more heat, speeding up the warming further in a feedback loop.
Glaciers showed the next biggest loss of ice volume, with more than 6tn tonnes lost between 1994 and 2017, about a quarter of global ice loss over the period. The shrinking of glaciers threatens to cause both flooding and water shortages in some regions, because as large volumes melt they can overwhelm downstream areas, then shrunken glaciers produce less of the steady water flow needed for agriculture.
Inès Otosaka, report co-author and a PhD researcher at the University of Leeds centre for polar observation and modelling, said: "As well as contributing to global mean sea level rise, mountain glaciers are also critical as a freshwater resource for local communities. The retreat of glaciers around the world is therefore of crucial importance, at both local and global scales."
For a deeper dive:
Published on Monday in Nature Communications, the study found that phosphorus, a mineral found in dust, is a key nutrient for an extensive glacier algae bloom on Greenland's ice sheet, known as the "dark zone." As the algae grow, the ice becomes darker, decreasing its ability to reflect sunlight and causing the ice to melt faster and sea levels to rise.
"It's important to understand the controls on algal growth because of their role in ice sheet darkening," Dr. Jenine McCutcheon, who led the study published in Nature Communications, told the University of Leeds. "Although algal blooms can cover up to 78 percent of the bare ice surfaces in the Dark Zone, their abundance and size can vary greatly over time," Dr. McCutcheon added.
Since 2000, the dark zone's melting season has "progressively started earlier and lasted longer," according to the University of Leeds. Glacier algal blooms are responsible for up to 13 percent of surface melting in this region, the study noted.
But until recently little was known about how these algal blooms developed.
Researchers found that phosphorus can cause the photosynthesis rate of the ice algae to improve significantly, McCutcheon said, according to the University of Leeds.
Although researchers examined dust sourced from local rock, they warned that dust can be transported thousands of miles by the wind.
"As dryland areas in northerly latitudes become even drier under climate change, we can expect to see more dust transported and deposited on the Greenland Ice Sheet, further fueling algal blooms," Associate Professor Dr. Jim McQuaid, who co-authored the study, noted.
"The findings of this study will improve how we predict where algal blooms will happen in the future, and help us gain a better understanding of their role in ice sheet albedo reduction and enhanced melting," Dr. McCutcheon added.
Researchers are also asking how these algal blooms will grow and darken in a warming climate.
"In 2019 our glaciers and ice sheets [are] already being darkened by dust, soot, and ash from our industrial world, which provides the perfect home for algae to flourish," Alexandre Anesio, a professor in Arctic biogeochemistry from Aarhus University, who was not affiliated with the University of Leeds study, told The Guardian. "As the organisms reproduce, they melt even more snow, which in turn allows them to proliferate again. So it's like a cycle. A very bad one."
Darkening ice is not just occurring on Greenland's ice sheets, according to The Guardian. It's happening globally, Professor Liane Benning of the German Research Center for Geosciences noted, also impacting the Alpine and Himalayan glaciers.
In Western Canada, wildfires fueled by climate change are also leaving ash on glaciers, staining the ice, creating habitats for algae and "accelerating the warming process in a feedback loop," Reuters reported.
"To be honest, I'm massively worried," Anesio told The Guardian. As the planet warms, researchers are rushing to find answers on glacial melting and its impact on biodiversity.
"I just hope that we are not crossing that tipping point because I don't think humans can adapt to the rates of changing climates at the moment," Anesio added.

Nevada City, California. Amidst a historic pandemic and social unrest, watching the accelerating impacts of climate change on the silver screen could create a sense of helplessness – or deepen the resolve to act. Emphasizing the latter, "Resilient by Nature" was the official theme of the recent Wild & Scenic Film Festival, an entirely virtual affair this year as a result of the COVID-19 pandemic.
More than a tagline, a sense of resilience was palpable throughout the online event, from the festival's stirring poster art, through the 100-plus documentaries that emphasized solutions, and even into the Zoom-based lobby, where attendees could drop in for a trivia game, casual conversation about the films, or even a BYOB beer tasting.
Held by the South Yuba River Conservation League (SYRCL), the 19th annual festival also played up opportunities to act on climate and other environmental issues, from participating in virtual activism workshops to simply getting outside: Self-guided excursions included the memorable "It's All Newt to Me," a guide to local amphibians.
Despite the creative ways to come together virtually, however, there was also disappointment that the event could not be held in person. Yet even this regret seemed unifying, at least in the virtual media lounge, where several filmmakers expressed an appreciation for being able to sit in on each other's video-conference interviews – pleasantly intimate conversations that any attendee could also enjoy from the comfort of their own couch, live or after the fact.
Flexibility was indeed a silver lining of the virtual festival experience, as audiences could view most of the films at any time, from any WiFi-enabled device, during the 11-day festival.
Five Documentaries to Add to Your Climate Watchlist
Resilience doesn't mean being Pollyannaish. The festival's standout climate documentaries tackled some of today's most sobering subjects, from the devastating Camp Fire that leveled Paradise, Calif. in 2018, to existential threats faced by indigenous Arctic communities experiencing intensifying oil and gas development.
Yet even these darkest of explorations reveal stories of fierce hope and determination, a reminder that heroic action on climate isn't just possible – it's happening now.
A glance at five documentaries* that may inspire your own conviction that worthy ways forward exist:
2040 (92 min. documentary, see trailer below)
How will 2040 look for the youth of today? Australian director and narrator Damon Gameau imagines a hopeful future for his four-year-old daughter, Ella – a vision that is profoundly realistic as it is based on solutions that are already available. Yet despite the film's optimism, there is no sugarcoating here. Gameau opens with a frank description of the climate crisis, albeit in terms a young child can grasp, demonstrating greenhouse gases with a steamy shower, for one example, and the danger of melting "glaciers" spilling out of the freezer, for another.
From there an expedition in "fact-based dreaming" takes off, as the film crisscrosses the world to explore some of the most promising current "solutions," including renewable energy, driverless cars, regenerative agriculture, marine permaculture, and empowering girls. For each category, we see resourceful and dedicated people in action today, followed by a fanciful, often humorous, dramatization of Ella's future, 20-something self, living in a world rich with these solutions. Will there be a giant world party in 2040 to celebrate the success of these efforts? There's no way to know whether Gameau's hopeful vision will or won't pan-out, but he points out that "we have everything we need to make it happen."
The Last Ice (83 min. documentary, see trailer below)
A new race is afoot in the waters between Canada and Greenland, where steadily melting sea ice is opening up the potential for faster shipping, increased oil extraction, and other commercial pursuits. As industries vie for space in the newly open waters, indigenous communities are rallying to protect the Arctic as they long have known it.
Taking home the Wild and Scenic "Best of the Fest" award, The Last Ice follows the personal journeys of several Inuit people whose lives are fundamentally tied to the land and wildlife, including a young man with dreams of being a hunter, who is deeply devoted to his sled dogs, and a woman working to keep her culture's ancient traditions alive, one text at a time. Mixing in archival footage and current science and political news, the film traces the threads of globalization that led to this moment over the past century, from the first forced resettlements of Inuit communities, to container ships cutting ever-more swiftly through the ice.
Through it all, there's stunning landscapes bedazzled with Northern lights; threatened, majestic animals like polar bears and narwhals; and a fervor for preserving Inuit ways of life. They combine to make the case that it's in our shared best interest to keep the Arctic from becoming a Wild West of extraction.
Public Trust | The Fight for America's Public Lands (96 min. documentary, see trailer below)
Spanning around 640 million acres and 28% of the United States' land, the nation's public lands are a uniquely American birthright – and the center of a fight over what to do with them. Do we exploit natural resources to further economic activity? Or do we preserve them from extractive industry use, to keep ecosystems and their beauty intact for future generations? Are those poles-apart choices the only two options?
This film documents both sides of what has become a cultural war over "the last large-scale public asset on the planet," from the deserts of Utah, the storied Boundary Waters of Minnesota, and the pristine Arctic National Wildlife Refuge – all threatened by oil and gas development and/or mining. But at its core, it's also a love letter to these places, and the people across the country working to protect diverse lands.
Winner of one the festival's pair of Jury Awards, Public Trust features a refreshing mix of personalities, including a hunter and investigative reporter from north Alabama. Feeling a deeply personal stake in the future of the public lands he grew up on, he is working to "follow the money" to help Americans see who's behind the destruction of our public lands.
During production, the Trump administration opened up large areas of public land to oil and gas development. Now, viewed from the fresh reality of a new administration, it may comfort some viewers to know that a Biden administration executive order has already begun halting oil and gas leasing on federal lands.
Rebuilding Paradise (91 min. documentary, see trailer below)
The deadliest fire in California history captured international attention when it decimated Paradise in 2018. But the town's story didn't end there.
It takes grit not to fast-forward through the first harrowing 10 minutes of this Ron Howard-directed documentary. Raw dashcam footage and emergency call audio blend into a nightmarish sequence of escape from the smoke-blackened town. As the flames leap higher, a police officer, alone in his cruiser, slows down to pass his own home, stiffly reports that it is engulfed in flames, then plunges back into the darkness.
From there, though, the film shifts from disaster to what comes next for locals who choose to stay and rebuild, like the former mayor who can't wait to rebuild, and the school counselor whose own home was spared but feels crushing guilt when she runs through her now-empty neighborhood.
As the year goes on, the pain doesn't subside – it somehow gets harder, for the counselor at least. There are water contamination issues to confront, the lingering trauma that strains the police officer's marriage, and an angry town meeting with PG&E, the utility whose faulty equipment started the fire.
But life has indeed gone on in Paradise. Somehow the high school remained standing, and six months after the Camp Fire, graduating seniors light up the field with exquisite joy.
Some people argue against rebuilding because the risk of another fire is too high. The former mayor, however, is defiant in his decision to stay. "A lot of people think it's wrong to rebuild. I'm 74, I don't give a damn. Is it right to build a house in a hurricane zone in Miami on the beach? This is where I want to be."
Wild Climate (27 min. documentary, see trailer below)
Got wanderlust? Enjoy a classic cross-country road from your living room with Virginia and Peter Sargent, as they cruise through rural America to get to know people whose livelihoods are threatened by climate change. Together with their dogs, Trout and Salmon, the Sargents camp out in public lands along their way to meet folks like farmers, hunters, fishermen, and even pro snowboarders, all seeing the increasing effects of climate change in their daily lives from intensified drought thwarting the Colorado farmer, to the impacts of wildfire on a hunting outfitting company in Idaho.
Interspersed with these stories is data confirming the science behind their experiences. For example, the pro snowboarder is already seeing his work threatened by diminishing snowpack; that makes sense given that western U.S. snowpack declined by 10-20% between the 1980s and 2000s, with another 60% loss anticipated in the next 30 years.
But more than a series of interviews and scenic views, the Sargents themselves give the film heart. These aren't just big city slickers swooping in and out of little towns to get the scoop and high-tail it to the next location. There's respect and even, at times, reverence for the people they meet along the way. Of the family farmers in Idaho, Peter says, "I think Purple Sage represents the best that family farms have to offer in this country. And there are so many more like them. And it's also an aspiration. It's the kind of family I want to create with Virginia."
Note: Some of the above films may not yet be available yet for general audience streaming. Keep an eye out for a local edition of the Wild and Scenic On Tour program, coming soon to roughly 250 local events across the U.S.

The Earth's climate has always been a work in progress. In the 4.5 billion years the planet has been spinning around the sun, ice ages have come and gone, interrupted by epochs of intense heat. The highest mountain range in Texas was once an underwater reef. Camels wandered in evergreen forests in the Arctic. Then a few million years later, 400 feet of ice formed over what is now New York City. But amid this geologic mayhem, humans have gotten lucky. For the past 10,000 years, virtually the entire stretch of human civilization, people have lived in what scientists call "a Goldilocks climate" — not too hot, not too cold, just right.
Now, our luck is running out. The industrialized nations of the world are dumping 34 billion tons or so of carbon into the atmosphere every year, which is roughly 10 times faster than Mother Nature ever did on her own, even during past mass extinction events. As a result, global temperatures have risen 1.2 C since we began burning coal, and the past seven years have been the warmest seven years on record. The Earth's temperature is rising faster today than at any time since the end of the last ice age, 11,300 years ago. We are pushing ourselves out of a Goldilocks climate and into something entirely different — quite literally, a different world than humans have ever lived in before.
How hot will the summers get in India and Pakistan, and how will tens of thousands of deaths from extreme heat impact the stability of the region (both nations have nuclear weapons)? How close is the West Antarctic ice sheet to collapse, and what does the risk of five or six feet of sea-level rise mean for people living in mobile homes on the Gulf Coast? The truth is, no one knows for sure. We are in uncharted terrain. "We're now in a world where the past is no longer a good guide to the future," said Jesse Jenkins, an assistant professor of engineering at Princeton University. "We have to get much better at preparing for the unexpected."
By all indications, President Biden and his team understand all this. And it's hard not to feel that after 30 years of dithering and denial and hypocrisy, the fight to save the climate has finally begun in earnest. In the 2020 election, nearly 70 percent of Biden's voters said climate change was a top issue for them. Biden has staffed his administration with the climate A-team, from Gina McCarthy as domestic climate czar to John Kerry as international climate envoy. He has made racial and environmental justice a top priority. And perhaps most important of all, he sees the climate crisis as an opportunity to reinvent the U.S. economy and create millions of new jobs.
"I think in Obama's mind, it was always about tackling the climate challenge, not making the climate challenge the central element of your economic policy," says John Podesta, a Democratic power broker and special adviser to President Obama who played a key role in negotiating the Paris Agreement. "Biden's team is different. It is really the core of their economic strategy to make transformation of the energy systems the driver of innovation, growth, and job creation, justice and equity."
Of course, there have been hopeful moments before: the signing of the Kyoto Protocol in 1997, when the nations of the world first came together to limit CO2 emissions; the success of Al Gore's documentary An Inconvenient Truth in 2006; the election of Obama in 2008 ("This was the moment when the rise of the oceans began to slow and our planet began to heal," Obama said in his speech accepting the Democratic presidential nomination that year); the Paris Agreement in 2015, when China finally engaged in climate talks. But all of these moments, in the end, led to nothing. If you look at the only metric that really matters — a graph of the percentage of CO2 molecules in the atmosphere — it has been on a long, steady upward climb. More CO2 equals more heat. To put it bluntly, all our scientific knowledge, all the political speeches, all the activism and protest marches have done zero to stop the accumulation of CO2 in the atmosphere from the burning of fossil fuels.
But hope rises again. The economic winds are lifting Biden's sails: The cost of wind and solar power has plummeted by 90 percent or so over the past decade, and in many parts of the world it's the cheapest way to generate electricity. Meanwhile, fossil-fuel dinosaurs are tottering: Big Coal is collapsing in real time and may disappear from American life in the next decade or so. ExxonMobil lost $22 billion last year and in August was delisted from the S&P 500. GM, long the staunch fossil-fuel loyalist of the U.S. auto industry, has pledged to go all-electric by 2035.
Globally, the signs of change are equally inspiring. Eight of the 10 largest economies have pledged to reach net-zero emissions by 2050. China, by far the world's largest carbon polluter in terms of raw tonnage (on a per capita basis, the U.S. and several other countries pollute far more), has promised to become carbon neutral by 2060. Some 400 companies, including Microsoft, Unilever, Facebook, Ford, Nestlé, and Pepsi, have committed to reduce carbon pollution consistent with the United Nations' 1.5 C target, which scientists have determined is the threshold of dangerous climate change. Many of these same companies are now calling on the Biden administration to cut overall U.S. carbon pollution by at least 50 percent below 2005 levels by 2030, a goal consistent with the 1.5 C target.
Big Money is also waking up to the risks and benefits of climate action. In his annual letter to investors, Larry Fink, the CEO of BlackRock, which manages $7.8 trillion in assets, challenged companies "to disclose a plan for how their business model will be compatible with a net-zero economy." In her confirmation hearing, Treasury Secretary Janet Yellen called climate change "an existential threat" and promised to create a team to examine the risks and integrate them into financial policy-making.
Still, these are only baby steps in a very long journey. And the clock is ticking. "When it comes to the climate crisis," says futurist Alex Steffen, "speed is everything." Every molecule of carbon we dump into the atmosphere is another molecule of carbon that will warm the climate for centuries to come, and in subtle and not-so-subtle ways, reshape the world we live in. The changes we are making are not reversible. If we magically stopped all carbon pollution tomorrow, the Earth's temperature would level off, but warm seas would continue melting the ice sheets and seas would keep rising for decades, if not centuries (last time carbon levels were as high as they are today, sea levels were 70 feet higher). Ocean acidification, caused by high CO2 levels, is already dissolving coral reefs and is having a major impact on the ocean food chain. Even after emissions stop, it will take the ocean thousands of years to recover.
Cutting carbon fast would slow these changes and reduce the risk of other climate catastrophes. But despite the world's newfound ambition, political leaders are not moving anywhere near fast enough. Even the goal of holding future warming to 2 C, which is a centerpiece of the Paris Agreement and considered the outer limits of a Goldilocks climate for much of the planet, is nearly out of reach. As a recent paper in Nature pointed out: "On current trends, the probability of staying below 2 C of warming is only five percent." If all countries meet the commitment they made in the 2015 Paris Agreement and continue to reduce emissions at the same rate after 2030, the paper argued, the probability of remaining below 2 C of warming rises to 26 percent ("As if a 26 percent chance was good," Swedish climate wunderkind Greta Thunberg pointed out in a tweet).
The great danger is not climate denial. The great danger is climate delay. Instead of pushing for changes tomorrow, world leaders and CEOs like to make virtuous-sounding statements about what they will do in 2050. And then in 2050, they will make virtuous-sounding statements about what they will do in 2070. Climate scientist Zeke Hausfather calls this the "empty radicalism" of long-term goals.
What's needed is action now. As climate envoy John Kerry put it at the World Sustainable Development Summit in February: "We have to now phase out coal five times faster than we have been. We have to increase tree cover five times faster than we have been. We have to ramp up renewable energy six times faster than we are. We have to transition to [electric vehicles] 22 times faster."
As an example of the seriousness of Biden's near-term ambition, he has proposed transitioning to 100 percent clean electricity by 2035, which means goodbye natural-gas plants, goodbye coal plants, and hello electric cars and battery storage. It's an astonishingly ambitious proposal, one that would require a remaking of the digital backbone of America at a breakneck speed. It will create hundreds of thousands of jobs, but if Biden is serious about getting it done, it will require retooling permitting laws and the environmental-review process that often stalls big infrastructure projects.
Demanding action now will also require shutting down the international financing schemes that support fossil fuels. China, Japan, and South Korea all claim to be doing their part in making carbon reductions at home, while at the same time they are financing 70,000 megawatts of coal power in places like Bangladesh, Vietnam, and Indonesia. In addition, state-run oil companies in places like China, Indonesia, and Saudi Arabia are on course to spend more than $400 billion over the next decade to expand oil infrastructure and exploration.
The goal of net-zero emissions is also problematic. "Net zero" is not the same thing as zero. It means that carbon pollution is either eliminated or offset by other processes that remove carbon from the atmosphere, such as forests or machines that capture CO2. Some of these offsets and technologies are more legit than others, opening the door to scams that claim to eliminate more carbon than they do.
In a way, the economic chaos caused by the pandemic has created a historic opportunity for the Biden administration. As one White House adviser tells me, "If you are going to pump billions of dollars into the economy, why not use those dollars to help us transition away from fossil fuels?" This is one of the central ideas behind Biden's $2 trillion infrastructure bill, which is now being negotiated in Congress. The bill includes a wide variety of climate-related initiatives, shaped around the twin pillars of Biden-era policy: clean-energy jobs and climate justice.
Already the pushback is fierce, especially in states that have benefited from the fracking boom. "The climate fight going forward is really about natural gas," says Leah Stokes, author of Short Circuiting Policy, an analysis of how special interests have derailed clean-energy policy for 30 years. Shortly after Biden issued his first round of executive orders aimed at the climate crisis, Texas Gov. Greg Abbott held a press conference in the middle of the gas fields "to make clear that Texas is going to protect the oil-and-gas industry from any type of hostile attack launched from Washington, D.C." In Florida, two bills were introduced that would preempt local governments from implementing plans to lower carbon pollution. In California and New York, residents are fighting transmission lines for offshore wind farms. Republicans, along with stalwart fossil-fuel allies like the Heritage Foundation, recently convened a private retreat in Utah to plot ways to "reclaim the narrative" on climate, while Republican Senators like Tennessee's Marsha Blackburn continue to recycle tired old rants about how the Paris Agreement is destroying American jobs.
None of this is surprising. And the fight will only get bigger and more ruthless as the clean-energy transition accelerates. Fossil fuels are emblematic of a culture, a way of life, a political hierarchy, and an empire of wealth that will not go quietly into the night.
Even among climate activists and progressives, there is wide disagreement about the best path forward. In Pennsylvania, Rep. Conor Lamb, a Democrat who supports Biden's climate goals, sees natural gas as indispensable. "You can't turn off natural gas in our society, at least in the Northeast of the United States at this time," Lamb tells me. "You just can't do it." Lamb advocates investments in expensive and unproven technology like carbon capture that could extend the life of fossil fuels. Then there are the eternal battles over nuclear power as a source of clean energy, which Lamb also supports. Others, like UC Berkeley energy professor Daniel Kammen, remain skeptical: "If low-cost, reliable, entirely safe nuclear can prove itself out, this is wonderful. . . . But there's a lot of big ifs."
More important, the fight for a stable climate is increasingly inseparable from a fight for justice and equity. Catherine Coleman Flowers, who was on a task force that helped shape Biden's climate policy during his campaign, grew up and works in Lowndes County, Alabama. "I see a lot of poverty here," Flowers says. "And I see a lot of people who suffer from the impacts of climate change — whether it is heat, or disease, or poor sanitation and polluted drinking water. You can't separate one from the other. They put sewage lagoons next to the houses of poor people, not rich people. They put oil pipelines through poor neighborhoods, not rich ones."
Internationally, rich nations of the world pledged to "mobilize" $100 billion by 2020 through the U.N.'s Green Climate Fund to help developing nations adapt to climate change. But only about $10 billion materialized. The U.S. was among the worst actors: Of the $3 billion President Obama promised, he funded only $1 billion before Trump canceled further payments (Biden has promised to make good on the commitment, and then some).
Whatever happens with Biden's climate and energy initiatives, we're living in a new world now. The faster we cut carbon, the more manageable the changes will be. But change is coming. The biggest fights of the future are less likely to be about natural gas and nuclear power than about sea walls and migration policies. "Adaptation is not sexy," says Alice Hill, who was an adviser to the Obama administration. "But it is inevitable." As climate impacts escalate, dangerous techno-fixes, such as solar geoengineering, which involves spraying particles into the stratosphere to reflect away sunlight and cool the planet, will likely become more tempting and more divisive, perhaps further diluting the will to quickly cut carbon pollution.
For more than 30 years now, scientists and politicians have been aware that our hellbent consumption of fossil fuels could push us out of the Goldilocks zone and force humans to live in a world we have never inhabited before. As Biden's push for climate action gets real, we will learn a lot about how serious human beings are about living on this planet, and how far the powerful and privileged are willing to go to reduce the suffering of the poor and vulnerable. If political leaders don't take the climate crisis seriously now, with all they know, with all they have been through already, will they ever? "Climate advocates keep saying, 'This is it, this is it, this is it,'" warns Podesta. "But this really is it. If we don't amp up and accelerate the energy transformation in this decade, we're goners — really goners."

Most of us know a bad drought when we see one: Lakes and rivers recede from their normal water lines, crops wither in fields, and lawns turn brown. Usually we think of these droughts as being triggered by a lack of rain, but scientists also track drought in other ways.
"The common ways to measure droughts are through precipitation, soil moisture and runoff," says Laurie S. Huning, an environmental engineer at the University of California, Irvine. Her most recent work adds another dimension to that by looking at water stored in snowpack.
Huning is the co-author of a study in the Proceedings of the National Academy of Sciences, with U.C. Irvine colleague Amir AghaKouchak, which developed a new framework for characterizing "snow droughts." These can occur when there's an abnormally low snowpack, which may be triggered by low precipitation, warm temperatures or both.
Their research is timely. This winter, southwestern states have received just a quarter to half of the average snow-water equivalent — the amount of water held in the snowpack — the key metric for determining a snow drought.
And that can have sweeping impacts. The water content of a snowpack can change the amount and timing of when runoff occurs, and that has implications for wildlife, ecosystems, water resources, flood control, hydropower and drought mitigation.
Snow droughts can also have far-reaching effects on agriculture — and economies. California's Central Valley, the heart of its agriculture industry, relies on snow melt from the Sierra Nevada. The state saw $2.7 billion in losses in the sector following low precipitation and warm temperatures during 2014-2015.

Snow droughts can also make conditions dire in regions that are already stressed by conflict and resource shortages. A snow drought in Afghanistan in 2017-2018 triggered crop failures and livestock loses that left 10 million people food insecure.
The concept of a "snow drought" has been around for several years, and it's been studied in certain key locations, but until now scientists and water managers lacked a worldwide method to assess them.
The study aims to solve that. Huning and AghaKouchak have developed a standardized snow-water equivalent index in an effort to better characterize and compare the duration and intensity of snow droughts around the world.
The results already reveal some areas of concern. Looking at data from 1980 to 2018, the researchers found a few hotspots where snow-droughts became longer and more intense during the 21st century.
The most notable area was the western United States, which saw a 28% increase in the length of periods of snow drought. Eastern Russia and Europe also saw increases, though less severe.
And on the flip side, some areas saw a decrease in snow drought duration, including the Hindu Kush, Central Asia, greater Himalayas, extratropical Andes and Patagonia.
"It's important to remember that not only does the snowpack vary but the impact that it has differs across the world," says Huning.
Huning hopes the framework developed for the study can help water managers better understand the amount and timing of snowmelt, and to integrate that with drought monitoring systems to recreate better resiliency and management of resources.
"We know that the snowpack is highly variable," she says. "Further development of this framework can improve our near real-time monitoring of drought."
The study didn't delve into the specifics of why snow droughts may be becoming more severe in certain places, but other studies have found that climate change is playing, and will play, a role in reducing snowpack in some areas — including western U.S. states.
A study by UCLA climate scientists published on Aug. 10 found that in California warmer temperatures will cause more rainfall and less snow during the winter in coming decades. This will likely increase flood risks and reduce the snowpack that usually melts slowly over the spring months.
Earlier research found that a decrease in Arctic sea ice leads to changes in atmospheric circulation that creates a high-pressure system, known as an atmospheric ridge, off the Pacific coast. These ridges deflect storms, pushing them northward and leaving the region high and dry. A particularly stubborn system that developed in 2013, nicknamed the "ridiculously resilient ridge," had a big hand in California's five-year drought, which extended until 2017.
Better understanding of how to measure and track snow droughts can give water managers another tool to help plan for similar droughts and to better manage this changing resource.
"Snow is a natural resource and, given the warming temperatures that some parts of the world will see, the amount of snow is changing," says Huning. "We need to recognize that there are so many different ways the environment and humans will be affected."

The annual Arctic thaw has kicked off with record-setting ice melt and sea ice loss that is several weeks ahead of schedule, scientists said, as the New York Times reported.
Meanwhile, thousands of miles away, there is open water in areas north of Alaska where it is rarely, if ever, seen, the Washington Post reported.
The accelerated ice melt in Greenland was caused by an usual weather pattern, where high-pressure air lingered, bringing warm air up from the south, which pushed the mercury 40 degrees Fahrenheit above normal temperatures. Add to that continuously cloudless skies and snowfall that is well below normal, and the conditions were ripe for melting across most of the ice sheet.
Last week, Greenland lost 2 billion tons of ice or about 45 percent of the surface in just one day. Measuring about 275,000 square miles, the ice melt was slightly larger than Texas, said Marco Tedesco, a geophysicist at Columbia University's Lamont-Doherty Earth Observatory, according to the New York Times.
While the high temperatures set a record early date for such widespread melting, there was slightly greater melting in 2012, but a bit later in June. That year, high pressure returned during the summer months, which caused record ice-sheet melt. Greenland lost 200 billion tons of ice that summer, the New York Times reported. But, so much melting this early in summer could be ominous, putting 2019 on pace to set a new record for ice loss, according to CNN.
"The melting is big and early," said Jason Box, a climatologist at the Geological Survey of Denmark and Greenland, as the Washington Post reported. In May, Box predicted that 2019 would be a big melt year for Greenland, as CNN reported.
His prediction was based on the lower than average snow cover in Western Greenland and the melt days that began in April, which is unusually early. The melt season also started three weeks earlier than average and earlier than the record-setting year of 2012, according to CNN.
The thin snow cover that fell this winter melts quickly, which exposes old snow and ice. The older snow absorbs more sunlight and, therefore, accelerates melting, according to the New York Times.
"These pulses of melting really change the face of the snow," Tedesco said, as the New York Times reported. "It can make the snow melt faster and faster."
While the fast melting is jarring, it will not contribute to sea level rise immediately since most of the water stays near the ice sheet and has the potential to refreeze. Only as the warm season continues does the water drain down through the ice and out into the ocean, according to the New York Times. Then the sea level will start to rise.
"Greenland has been an increasing contributor to global sea level rise over the past two decades," said Thomas Mote, a scientist at the University of Georgia who studies Greenland's climate, as CNN reported. "And surface melting and runoff is a large portion of that."
The current melting, while unusual and alarming, has precedent. Mote pointed to 2012, 2010 and 2007 as notable melt years that were once unthinkable, but now might be the new normal.
"We've seen a sequence of these large melt seasons, starting in 2007, that would have been unprecedented earlier in the record," he said, as CNN reported. "We didn't see anything like this prior to the late 1990s."
