Antarctica and Greenland Raised Sea Levels More Than Half an Inch in Just 16 Years, New NASA Data Shows
Greenland and Antarctica have raised global sea levels by more than half an inch in the last 16 years, according to data from the most advanced laser that the National Aeronautics and Space Administration (NASA) has ever launched into space to observe the earth.
While the figures themselves are consistent with other studies, as The New York Times pointed out, the satellite laser allows researchers a much more precise picture of how polar ice is changing over time, which helps determine the role of the climate crisis and plan for future sea level rise.
"We've all been waiting for this new dataset," Lamont-Doherty Earth Observatory research professor Robin Bell told NPR.
The study, published in Science Thursday, combines data from two NASA satellites: the original Ice, Cloud and land Elevation Satellite (ICESat), which took measurements from 2003 to 2009, and ICESat-2, launched in 2018. The two satellites allowed researchers to measure changes in ice mass from 2003 to 2019, and to calculate that Greenland and Antarctica contributed 0.55 inches to sea level rise during that time. That's around a third of the global total, which was also driven by the expansion of oceans as they warm, NPR explained.
"If you watch a glacier or ice sheet for a month, or a year, you're not going to learn much about what the climate is doing to it," University of Washington glaciologist and lead study author Ben Smith said in a NASA press release. "We now have a 16-year span between ICESat and ICESat-2 and can be much more confident that the changes we're seeing in the ice have to do with the long-term changes in the climate."
The data also revealed that Greenland's ice sheet lost an average of 200 gigatons of ice per year and Antarctica's lost an average of 118. That's more than 5,000 gigatons total, NPR reported. To put that in perspective, one gigaton is enough to fill 400,000 Olympic-sized swimming pools.
But the satellite data also helped show how the ice was being lost. In Antarctica, the East actually gained mass, probably because of increased precipitation, The New York Times reported. But this was offset by losses in West Antarctica and the Antarctic Peninsula. In West Antarctica, 30 percent of that loss was due to floating ice, which either calves icebergs or melts from below due to warm ocean water. While this ice cannot contribute directly to sea level rise because it is already floating, its loss destabilizes the so-called "grounded ice" that can.
"It's like an apple tart and the ice shelves are like the wall of pastry around the edges of the tart," Scripps Institution of Oceanography at the University of California-San Diego glaciologist and study coauthor Helen Fricker explained to NPR. "And if those walls are too thin or they're not baked well enough, then the filling will ooze out."
In Greenland, two thirds of the ice loss was due to surface melting, something that rarely occurs in Antarctica, The New York Times said. Greenland also lost a lot of mass from its coastal glaciers, according to NASA. Its Kangerdulgssuaq and Jakobshavn glaciers have shrunken by 14 to 20 feet per year.
NASA explained why its satellites were able to provide such a detailed portrait:
ICESat-2's instrument is a laser altimeter, which sends 10,000 pulses of light a second down to Earth's surface, and times how long it takes to return to the satellite – to within a billionth of a second. The instrument's pulse rate allows for a dense map of measurement over the ice sheet; its high precision allows scientists to determine how much an ice sheet changes over a year to within an inch.
The researchers took tracks of earlier ICESat measurements and overlaid the tracks of ICESat-2 measurements from 2019, and took data from the tens of millions of sites where the two data sets intersected. That gave them the elevation change, but to get to how much ice has been lost, the researchers developed a new model to convert volume change to mass change. The model calculated densities across the ice sheets to allow the total mass loss to be calculated.
This level of detail is essential for helping coastal residents and governments plan for sea level rise, which is expected to reach two to six feet by 2100, according to CNBC.
"Our goal is to be able to tell every coastal community what they can plan on [in] the coming decades," Bell told NPR. "To be able to do that, we both need to measure how the ice is changing but also understand better why it's changing."

The number of forest fires in Brazil's Amazon rainforest increased 28% in July in comparison to last year, the country's National Institute for Space Research reported Saturday.
Government Measures Not Enough<p>On July 16, the Brazilian government banned burning in the Pantanal wetlands and the Amazon forest for four months.</p><p>President Bolsonaro also issued an order in May for the military to coordinate environmental actions in the Amazon.</p><p>But experts say the fire numbers indicate the government's response has not been effective.

What better place to build a Doomsday Vault than the remote, snow-covered islands of Norway's Arctic Svalbard? Sitting around 1,000 kilometers from the North Pole, the facility is buried in permafrost to protect the precious seed samples housed there. But a freak heatwave is causing the region's ice to melt.
Deep Trouble?<p>The <a href="https://www.sciencealert.com/here-s-what-it-s-like-inside-the-doomsday-vault-that-stores-every-known-crop-on-the-planet" target="_blank">Svalbard Global Seed Vault</a> – also known as the Doomsday Vault – is a gigantic bunker, sitting deep inside a mountain surrounded by snowy wastelands. The facility stores close to <a href="https://www.seedvault.no/about/the-facility/" target="_blank">900,000 seed samples</a> from around the world and acts as a sort of back-up plan for agriculture, should disaster render parts of the planet unlivable or the world suffer a catastrophe, such as nuclear war or extreme climate change.</p><p>It's been described as an "<a href="https://www.newscientist.com/article/2235116-svalbard-doomsday-vault-gets-first-big-seed-deposit-since-upgrade/" target="_blank">insurance policy for food security</a>."</p><p>Inside the vault, <a href="https://www.sciencealert.com/here-s-what-it-s-like-inside-the-doomsday-vault-that-stores-every-known-crop-on-the-planet" target="_blank">temperatures are kept below minus 18℃</a>, cold enough to keep the seed samples safe for at least 200 years, even without backup power. But climate change is causing problems for the vault.</p><p>In 2016, which was the <a href="https://climate.nasa.gov/news/2841/2018-fourth-warmest-year-in-continued-warming-trend-according-to-nasa-noaa/" target="_blank">warmest year on record according to NASA</a>, soaring temperatures caused <a href="https://www.telegraph.co.uk/news/2017/05/20/doomsday-arctic-seed-vault-breached-permafrost-melts/" target="_blank">meltwater to breach the vault's entrance tunnel</a>.

The Heat Is On<p>Warming in the islands has been underway for some time. Figures for 2017 show average temperatures are between 3-5℃ hotter than in 1971, according to the <a href="https://www.miljodirektoratet.no/globalassets/publikasjoner/M1242/M1242.pdf" target="_blank">Climate in Svalbard 2100</a> report, with the largest increases affecting the inner fjords.</p><p><span></span>Between 2071 and 2100, average temperatures throughout the archipelago will increase by between 7-10℃, the report predicts, shortening the snow season and causing loss of near-surface permafrost.</p><p><span></span>What's happening in Svalbard is symptomatic of wider changes impacting the Arctic expanse, which is <a href="https://www.upi.com/Science_News/2018/12/12/NOAA-Arctic-warming-at-twice-the-rate-of-the-rest-of-the-planet/5141544580754/" target="_blank">warming twice as fast as the rest of the planet</a>.

As climate activists, we can't fight the climate crisis without considering the systemic impacts that environmental racism and White supremacy have on the frontline communities most affected by pollution and our warming world.
Do a Social Media Audit and Reconsider Who You Follow<p>As the movement for social and environmental justice continues, it's important to pay attention to the voices and media outlets you're consuming information from. Take a few minutes to look at your social media feeds – do you follow people of color and diverse voices? Do you follow credible news sources?</p><p>Take a look at what you've posted so far and think about <em>why </em>you posted. As allies, we can help the movement by centering our posts and online actions around supporting the activists and organizers on the ground. Think or ask about how you can best amplify these causes – for many that could mean retweeting or reposting, educating your followers, or even by directing followers to donation or petition pages.</p><p>Next, take a look at who you follow. It can be easy to get stuck in a <a href="https://www.nbcnews.com/better/lifestyle/problem-social-media-reinforcement-bubbles-what-you-can-do-about-ncna1063896" target="_blank">social media bubble</a>, where your social feed will filter out opinions you may not necessarily agree with. By continuing to audit your social media and expand your range of news sources or pages you follow to have varying opinions or backgrounds, you ensure you have a well-rounded news feed and could even hear about a news story that you may not have known about before!</p><p>For many environmental justice fights around the US and world, local news outlets and activists may be the ones covering the story first. By taking a look at our follower lists, it gives us space to recognize any information gaps! Check out the accounts of people you trust to follow useful resources and activists.</p><p>Need some recommendations to start you off? Here are some of the <a href="https://www.climaterealityproject.org/blog/top-climate-experts-follow-twitter" target="_blank">top climate scientists</a> and <a href="https://www.climaterealityproject.org/blog/young-climate-activists-follow-twitter" target="_blank">youth activists</a> we suggest you follow on social media.</p>
Challenge Yourself and Others to Continue Learning<p>It's okay not to know everything. In fact, it's completely normal.</p><p>One of the best parts of being a climate advocate is that we continue to learn and grow with the climate movement and science. To protect our air, water, and land from pollution, we have to stay up to date with the newest science and solutions – it's the same thing when advocating for social and environmental justice!</p><p>For many, this means keeping up to date on social media and in the news with what protests are happening and why, how we can support them, and what local organizations are doing to defend their communities. It also means trying to keep an ear out for the stories that major outlets aren't covering extensively.</p><p>Take the <a href="https://www.nbcnews.com/news/us-news/atlantic-coast-pipeline-canceled-after-years-delays-accusations-environmental-injustice-n1232987" target="_blank">recent victory in the fight against the Atlantic Coast Pipeline for example</a>. Local environmental justice groups in West Virginia, Virginia, and North Carolina had been fighting for years against the pipeline. When it was canceled a few weeks ago, activists celebrated, but the story never seemed to get the same level of attention as the latest tweet from the White House.</p><p>Social media gives us the opportunity to learn from others with varied experiences and gain resources to information that can make us better activists.</p>
Expect to Make Mistakes and Learn to Listen<p>We will all make mistakes. It's a part of continuing to educate ourselves and growing as an ally and activist. Even the most experienced advocates have said the wrong thing or made a mistake in their time.</p><p>For many of us, especially White climate activists, these may be relatively new concepts, but we must make the fight against racism our fight. Take a look back at what you've posted before and learn from any past mistakes, using this moment to learn what went wrong and share what you learned with others. By educating yourself, you can help others who may be experiencing similar mistakes or have questions.</p><p>Additionally, the best way to learn about the impacts of systemic racism on frontline communities being impacted by police brutality or climate change is to listen. Give Black activists and people of color an opportunity to tell their stories and give yourself time to reflect on their experiences. It may (and probably will be) uncomfortable in some moments but it's necessary to make progress in a movement where we can fight together for long-awaited justice.</p>
Use Your Platform and Following to Amplify Diverse Voices<p>Whether you have a big social media following, only follow close family and friends on social media, or don't have social media accounts at all – use the platform or online environment you have to amplify the voices of Black activists and people of color.</p><p>It can be as simple as sending an email to close friends or retweeting posts from local organizers. Sharing information from those on the front lines to those who trust and follow you not only helps local activists but can help educate others!</p><p>For many, you're a trusted messenger. What does that mean? You can read more about it in one of our <a href="https://www.climaterealityproject.org/blog/why-trusted-messengers-matter" target="_blank">past blogs</a>, but here's a quick definition from <a href="https://www.bu.edu/ise/2019/04/16/trusted-messenger/" target="_blank">Boston University:</a><br>"People believe people whom they trust, and they're more likely to act based on the recommendation of that influential other person."</p><p>Your family, friends, and followers trust you – use that privilege as an opportunity to educate them and amplify the voices of those leading the social and environmental justice fight!</p>

As American school officials debate when it will be safe for schoolchildren to return to classrooms, looking abroad may offer insights. Nearly every country in the world shuttered their schools early in the COVID-19 pandemic. Many have since sent students back to class, with varying degrees of success.

Final Grades<p>There is no perfect way to reopen schools during a pandemic. Even when a country has COVID-19 under control, there's no guarantee that schools can reopen safely.</p><p>But the policies and practices of countries that have had some initial success with schools point in the same direction. It helps to slowly stage the reopening. Strict mask wearing and social distancing is critical, both in schools and surrounding communities. And both officials and families need <a href="https://onlinelibrary.wiley.com/doi/full/10.1111/puar.13252" target="_blank">reliable and up-to-date data</a> so that they can continually assess outbreaks – and change course quickly if necessary.<span></span></p>

In the United States, over 2,000 acres of agricultural land are sold every day for housing or commercial development, according to the American Farmland Trust. This has especially affected Black farmers who, since 1920, have seen nearly a 90 percent decline in land ownership, according to the U.S. Census.
