2020 was the largest wildfire season in California's modern history, according to state agency Cal Fire. And, as the climate crisis continues to increase fire risk, there are concerns that 2021 could be just as devastating.
<p>To adapt to this new normal, California leaders Thursday announced a more-than half a billion dollar plan to prevent and prepare for wildfires.</p><p>"The hots are getting hotter. The dries are getting drier. There's a new reality," Newsom said as he announced the plan, as <a href="https://www.mercurynews.com/2021/04/08/newsom-unveils-536-million-plan-for-california-wildfires/" target="_blank">The Mercury News reported.</a> "If you don't believe in climate change, if you don't believe in science, you believe your own damn eyes. Something is happening as it relates to the issue of climate that's exacerbating conditions and making the challenge of wildfire suppression and prevention that much more ominous."</p>

<p>The $536 million Wildfire Prevention and Resiliency package earmarks $350 million for forest management, including vegetation thinning, as well as $25 million to help homeowners pay for prevention measures on their properties, <a href="https://www.theguardian.com/us-news/2021/apr/08/california-wildfire-plan-gavin-newsom" target="_blank" rel="noopener noreferrer">The Guardian reported</a>. Newsom also touted the importance of adapting controlled burning techniques that were practiced for centuries by the state's first inhabitants. These smaller, necessary fires were suppressed by European settlers, contributing to the buildup of dried vegetation that has fueled historic blazes in recent years.<br></p><p>The new measure is an arrangement with California state lawmakers and has been introduced in both the House and Senate, according to The Mercury News. It is expected to pass Monday and be signed by Newsom next Tuesday. It builds on Newsom's pledge last week to hire around 1,400 new firefighters.</p>
<p>"For every dollar we spend on wildfire prevention, our state saves $6 to $7 in damage. But it's not just about saving money – this is about saving Californians' lives, their homes, and their livelihoods," Senate President Pro Tempore Toni G. Atkins (D-San Diego) said in a <a href="https://sd39.senate.ca.gov/news/20210408-senate-applauds-agreement-wildfire-prevention-and-resiliency" rel="noopener noreferrer" target="_blank">statement</a>.

<p>Indeed, San Francisco is in the midst of its second driest two-year stretch in recorded history, according to The Mercury News. The state's rainy season this winter was the third driest on record and the snowpack of the Sierra Nevada mountains was just 59 percent of its historic average as of April 1.</p><p>This leads experts to predict another devastating fire season. California Natural Resources Secretary Wade Crowfoot warned reporters thursday that summer of 2021 promised "more of the same," as <a href="https://www.nbcnews.com/news/us-news/california-pour-536-million-fire-prevention-amid-drought-concerns-n1263536" rel="noopener noreferrer" target="_blank">NBC News reported</a>.</p><p>"The science is clear: Warming winter temperatures and warming summer temperatures are creating more dangerous and challenging wildfire conditions," he said. "Clearly much more needs to be done on a proactive, upfront basis to reduce the risk of catastrophic wildfire."</p>

Delta-8 THC is a cannabis product that has become a bestseller over the past few months, as many consumers find they can legally purchase it from CBD retailers. Its proponents say that Delta-8 THC will give you a nice little buzz, minus some of the more intense feelings (including paranoia) that are sometimes associated with marijuana.
Delta-8 THC is being marketed as a legal option for consumers who either don't live in a state with legal cannabis, or are a little apprehensive about how traditional psychoactive THC products will affect them. But is it all it's cracked up to be? Let's take a closer look, exploring what Delta-8 THC is, how it differs from other THC products, and whether it's actually legal for use.
<h2>What is Delta-8 THC?</h2><p>To better understand <a href="https://www.nytimes.com/2021/02/27/health/marijuana-hemp-delta-8-thc.html" target="_blank">Delta-8 THC</a>, it helps to cover some basics about THC and cannabis.</p><p>Cannabis plants come chock full of different <a href="https://www.nccih.nih.gov/health/cannabis-marijuana-and-cannabinoids-what-you-need-to-know" rel="noopener noreferrer" target="_blank"><em>cannabinoids</em></a>. These are naturally-occuring chemical compounds that bind with receptors throughout your body. They can offer a wide range of mental, emotional, and physical effects; indeed, the healing and therapeutic properties marijuana or <a data-linked-post="2648563694" href="https://www.ecowatch.com/strongest-cbd-oil-2648563694.html" target="_blank">CBD products</a> offer can be attributed to cannabinoids.</p><p>One of the most common cannabinoids is what's known as Delta-9 THC. Simply put, this is the part of marijuana that gets you "high." It's worth noting that Delta-9 THC remains illegal in many states, except for in the most minute doses, and is still illegal at the federal level. CBD products are made with trace amounts of THC, ensuring that consumers can enjoy positive health effects in a perfectly legal way, without the risk of getting high.</p><p>On a chemical level, <a href="https://www.nytimes.com/2021/02/27/health/marijuana-hemp-delta-8-thc.html" rel="noopener noreferrer" target="_blank">Delta-8 THC</a> is not too different from Delta-9 THC; the distinction comes down to just a few molecules. But those molecules make a big practical impact: Delta-8 THC will give you a buzz, but the psychoactive effects are considerably milder than with Delta-9 THC.</p><p>More specifically, many cannabis enthusiasts report that Delta-8 THC helps them feel good but also leaves them relatively clear-headed; and, it doesn't produce the anxiety or jitteriness that often characterize a Delta-9 THC high.</p><p>Additionally, because of the way the law is written regarding Delta-9 THC, some CBD companies now sell Delta-8 THC products in places where traditional cannabis is still illegal.</p><h2>What's the Difference Between Delta-9 THC and Delta-8 THC?</h2><p>Here are the primary differences to note between Delta-9 and Delta-8 THC:</p><ul class="ee-ul"><li>Delta-9 THC is the primary psychoactive ingredient found in marijuana. In other words, it's the part that gets you high.</li><li>Though some states have found workarounds, Delta-9 THC is still illegal under federal law.</li><li>Delta-8 THC is also found in the cannabis plant, though it's not quite as powerful or as well-known. </li><li>Delta-8 THC is milder in its psychoactive effects. And, it's not <em>technically </em>illegal under current law.</li></ul><p>These are just a few of the key distinctions to keep in mind. Delta-8 THC is popular among consumers who want a smoother high, and don't want to violate federal law.</p><h2>Is Delta-8 THC Legal?</h2><p>We noted that Delta-8 THC is not <em>technically </em>illegal. Here, we need to get into some of the nuanced legal considerations that surround this substance.</p><p>First of all, there are plenty of cannabis companies that actively promote Delta-8 THC as a legal way to get high. Again, that's technically true, but is still a point of debate for some.</p><p>For one thing, it's not explicitly listed as an illegal substance. While federal laws, and some state laws, specifically ban Delta-9 THC, Delta-8 THC is never mentioned. More to the point, though, many proponents will cite the<a href="https://www.usda.gov/farmbill" rel="noopener noreferrer" target="_blank"> 2018 Farm Bill</a>. This law legalized several industrial hemp products on a national level, including CBD.</p><p>The Farm Bill also includes some fairly nuanced positions regarding THC. In summary, the law says that hemp and cannabis-derived products are legal so long as they contain less than 0.3 percent Delta-9 THC.</p><p>With that said, some lawyers contend that Delta-8's heyday may soon come to an end. That's because the Farm Bill clears it only so long as it's derived directly from hemp; most of the Delta-8 THC products sold today aren't made from hemp, but rather from synthetically-altered CBD.</p><p>Some of these issues are a little fuzzy, and <a href="https://www.rollingstone.com/culture/culture-features/delta-8-thc-legal-weed-explained-1113859/" rel="noopener noreferrer" target="_blank">the legal future of Delta-8 THC</a> remains a little uncertain. For now, though, many experts would argue that it is legal to purchase.</p><h2>What Kinds of Delta-8 THC Products Are Available?</h2><p><em>Each product featured here has been independently selected by the writer. If you make a purchase using the links included, we may earn commission.</em></p><p>If you're looking to try Delta-8 THC products, you'll certainly find plenty of different products. Dispensaries and legal cannabis stores currently have a trove of products that use this cannabinoid. Some examples include:</p><ul class="ee-ul"><li>Vape cartridges, tinctures, and capsules.</li><li>Beverages made with Delta-8 THC, including some seltzers.</li><li>Edibles, including Delta-8 THC gummy bears, chocolate bars, and more.</li></ul><p>The cannabis industry has really been running with Delta-8 THC, finding creative ways to bring it to market. And chances are, even more products will be springing up in the weeks and months to come. </p><p>It's very important to note that you should only purchase Delta-8 THC products from reputable brands and established cannabis retailers. We do not recommend purchasing any products that contain Delta-8 THC from gas stations or vape shops. If you are looking for a reputable place to explore these products, here are a few brands that we trust and recommend:</p>
<h2>What are the Pros and Cons of Delta-8 THC?</h2><p>As you consider whether Delta-8 THC is worth your time, it may be helpful to weigh the pros against the cons.</p><p><strong>Pros</strong></p><p>Let's start with some of the positives:</p><ul class="ee-ul"><li>Delta-8 THC does have psychoactive effects, but it's a milder effect than with traditional Delta-9 THC.</li><li>Delta-8 THC is currently legal and widely accessible in multiple states.</li><li>There are a wide number of products that use Delta-8 THC.</li></ul><p><strong>Cons</strong></p><p>Now, a few of the downsides.</p><ul class="ee-ul"><li>Delta-8 THC isn't quite as commonplace as other cannabis products, including CBD, and some of the options on the market are expensive.</li><li>While this substance is technically legal, there are plenty of uncertainties over its legal future. It's something you want to keep in mind.</li><li>As a relatively new product, Delta-8 THC products are not regulated by the FDA and there is not independent testing in place to verify that it is safe or pure.</li></ul><p>As with any cannabis product, Delta-8 THC has its pros and cons. As you seek the cannabis product that's best for you, it's largely a matter of personal preference.</p><p>Also note that smoking, vaping, or otherwise imbibing any kind of cannabis-related product can carry some medical risks and negative health consequences. If you have any specific concerns, we recommend consulting with your doctor before you try any Delta-8 THC product.</p><p><em><strong>Josh Hurst </strong></em><em>is a journalist, critic, and essayist.

Harmful algal blooms may be even more harmful than we thought.
<p>They have already been shown to kill the <a href="https://www.ecowatch.com/toxic-algae-blooms-florida-1915716568.html" target="_self">fish that swim</a> in the water they infest or the <a href="https://www.ecowatch.com/toxic-algae-dogs-nyc-2640040842.html" target="_self">animals that drink</a> from it. Now, new research indicates they could even poison the air. In a<a href="https://www.tandfonline.com/doi/full/10.1080/10402381.2021.1881191" target="_blank"> study published in Lake and Reservoir Management this month</a>, scientists for the first time detected an airborne instance of the algal toxin anatoxin-a (ATX), also known as "very fast death factor."</p><p>"ATX is one of the more dangerous cyanotoxins produced by harmful algal blooms, which are becoming more predominant in lakes and ponds worldwide due to global warming and <a href="https://www.ecowatch.com/climate-change/" target="_self">climate change</a>," study lead author Dr. James Sutherland of the Nantucket Land Council said in a <a href="https://www.scimex.org/newsfeed/algal-blooms-can-release-very-fast-death-factor-toxin-into-the-air" target="_blank">press release</a>.</p>
<p>ATX is a toxin made by cyanobacteria, or blue-green algae. Despite their name, these single-celled organisms are not plants but rather bacteria that can photosynthesize. The toxin can cause loss of coordination, muscular twitching and respiratory paralysis. It has been known to kill livestock, pets and other animals that drink contaminated water.</p><p>"Although no previous studies have documented the capture of airborne ATX molecules or cyanobacteria cells containing ATX, we hypothesized that ATX could become airborne under certain environmental conditions," the study authors wrote.</p><p>To test this idea, the scientists devised a way to sample the air above a pond in Nantucket, Massachusetts dealing with a harmful algal bloom (HAB). They brought an air sampling device to the shore on windy days and collected airborne particles on filters. They also tested the water for the presence of the toxin.</p>
<p>The scientists collected their samples between July and October of 2019. They detected ATX in the water at concentrations as high as 21 nanograms per milliliter, <a href="https://www.sciencealert.com/scientists-have-found-that-a-dangerous-algal-bloom-toxin-can-be-found-in-the-air" target="_blank">Science Alert reported</a>. And, on one foggy and windy day in September, they detected it in the air also. They recorded an average of 0.87 nanograms per filter on their air sampling device, which would equal an airborne exposure of 0.16 nanograms per meter squared.</p><p>The researchers are not sure how the toxin ended up in the air, but think the wind might have blown it in small droplets from the pond, and then the fog allowed it to persist for longer than usual. In any case, it is a problem worth investigating further.</p><p>"These findings indicate that emission of ATX molecules, or cyanobacteria containing ATX, during HABs presents a potential human health exposure not previously examined," the researchers wrote.</p>
<p>Harmful algal blooms are a problem for many other reasons, of course. They can deprive water of oxygen as they decompose, killing fish and degrading water quality, the press release explained. They are also made worse by human activity, according to Science Alert. They are fed partly by excess nutrient pollution from agricultural runoff. As Sutherland noted, they are also <a href="https://www.ecowatch.com/harmful-algal-blooms-2646107064.html" target="_self">exacerbated</a> by the climate crisis. The cyanobacteria prefer warmer water temperatures, and heavy rain from extreme weather events can wash more fertilizer and other nutrients into bodies of water.</p><p>The research just signals another reason to be wary of pond scum.</p><p>"People often recreate around these lakes and ponds with algal blooms without any awareness of the potential problems," Sutherland said in the press release. "Direct contact or inhalation of these cyanotoxins can present health risks for individuals, and we have reported a potential human health exposure not previously examined."</p>

About 60% of methane emissions are caused by human activity, and U.S. oil and gas operations are a <a href="https://nexusmedianews.com/top_story/methane-pollution-increased-driven-in-north-america-by-fracking/?swcfpc=1&utm_campaign=Hot%20News&utm_medium=email&_hsmi=120270142&_hsenc=p2ANqtz--p2urNftjYuA2xHzLZGhatJL-27AxwfYAkMFENp3mkR4lWVJPUGTMs6Q1NtM27LvfxHWPm1J8HMzgZgfSBBHPOFrBVOQ&utm_content=120270142&utm_source=hs_email" target="_blank" rel="noopener noreferrer">major driver</a> of recent methane pollution increases.</p>
<p>"Although increased fossil emissions may not be fully responsible for the recent growth in methane levels," NOAA research chemist Ed Dlugokencky said in a statement, "reducing fossil methane emissions are an important step toward mitigating climate change." </p>
<p>Methane is a far more potent heat-trapping gas than carbon dioxide, and scientists are worried global warming could be triggering accelerated methane releases from tropical wetlands and melting Arctic permafrost. "Our path to net zero is obvious, challenging and necessary," Martin Siegert, a professor at the Imperial College London, told The Guardian, "and we must get on with the transition urgently."</p>

This dramatic change is like a human meteorite hitting Earth."</blockquote><blockquote>But he added: "If countries make plans now to put society on a path of sustained and dramatic cuts to emissions from today, we can avoid ever-rising emissions and the dangerously accelerating impacts of climate change."</blockquote>

Globally, only one in 50 new cars were fully electric in 2020, and one in 14 in the UK. Sounds impressive, but even if all new cars were electric now, it would still take 15-20 years to replace the world's fossil fuel car fleet.
<p>
<br/>
</p>
<p>The emission savings from replacing all those internal combustion engines with zero-carbon alternatives will <a href="https://doi.org/10.1038/s41558-018-0121-1" target="_blank">not feed in fast enough</a> to make the necessary difference in the time we can spare: the <a href="https://theconversation.com/for-a-carbon-neutral-uk-the-next-five-years-are-critical-heres-what-must-happen-151708" target="_blank">next five years</a>. Tackling the climate and air pollution crises requires curbing all motorized transport, particularly private cars, as quickly as possible. Focusing solely on electric vehicles is slowing down the <a href="https://unfccc.int/climate-action/race-to-zero-campaign" target="_blank">race to zero emissions</a>.</p><p>This is partly because electric cars aren't <a href="https://www.eea.europa.eu/publications/transport-and-environment-report-2020" target="_blank">truly zero-carbon</a> – mining the raw materials for their batteries, manufacturing them and generating the electricity they run on produces emissions.</p><p>Transport is one of the most challenging sectors to decarbonize due to its <a href="https://www.eea.europa.eu/themes/transport/term/increasing-oil-consumption-and-ghg" target="_blank" rel="noopener noreferrer">heavy fossil fuel use</a> and reliance on <a href="https://www.transportforqualityoflife.com/u/files/The%20carbon%20impact%20of%20the%20national%20roads%20programme%20FINAL.pdf" target="_blank" rel="noopener noreferrer">carbon-intensive infrastructure</a> – such as roads, airports and the vehicles themselves - and the way it embeds <a href="https://www.itf-oecd.org/reversing-car-dependency" target="_blank" rel="noopener noreferrer">car-dependent lifestyles</a>. One way to reduce transport emissions relatively quickly, and potentially <a href="https://doi.org/10.1016/j.enpol.2010.07.017" target="_blank" rel="noopener noreferrer">globally</a>, is to swap cars for cycling, e-biking and walking – active travel, as it's called.</p><p>Active travel is cheaper, healthier, better for the environment, and no slower on congested urban streets. So how much carbon can it save on a daily basis? And what is its role in reducing emissions from transport overall?</p><p><a href="https://doi.org/10.1016/j.trd.2021.102764" target="_blank">In new research</a>, colleagues and I reveal that people who walk or cycle have lower carbon footprints from daily travel, including in cities where lots of people are already doing this. Despite the fact that some walking and cycling happens on top of motorized journeys instead of replacing them, more people switching to active travel would equate to lower carbon emissions from transport on a daily and trip-by-trip basis.</p>
<h2>What a Difference a Trip Makes</h2><p>We observed around 4,000 people living in London, Antwerp, Barcelona, Vienna, Orebro, Rome and Zurich. Over a two-year period, our participants completed 10,000 travel diary entries which served as records of all the trips they made each day, whether going to work by train, taking the kids to school by car or riding the bus into town. For each trip, we calculated the carbon footprint.</p><p>Strikingly, people who cycled on a daily basis had 84% lower carbon emissions from all their daily travel than those who didn't.</p><p>We also found that the average person who shifted from car to bike for just one day a week cut their carbon footprint by 3.2kg of CO₂ – equivalent to the emissions from driving a car for 10km, eating a <a href="https://www.bbc.co.uk/news/science-environment-46459714" target="_blank" rel="noopener noreferrer">serving of lamb or chocolate</a>, or <a href="https://www.bbc.com/future/article/20200305-why-your-internet-habits-are-not-as-clean-as-you-think" target="_blank" rel="noopener noreferrer">sending 800 emails</a>.</p><p>When we compared the life cycle of each travel mode, taking into account the carbon generated by making the vehicle, fueling it and disposing of it, <a href="https://doi.org/10.1016/j.trd.2021.102764" target="_blank" rel="noopener noreferrer">we found</a> that emissions from cycling can be more than 30 times lower for each trip than driving a fossil fuel car, and about ten times lower than driving an electric one.</p>
<p><a href="https://doi.org/10.1016/j.gloenvcha.2021.102224" target="_blank" rel="noopener noreferrer">We also estimate</a> that urban residents who switched from driving to cycling for just one trip per day reduced their carbon footprint by about half a tonne of CO₂ over the course of a year, and save the equivalent emissions of a <a href="https://www.bbc.co.uk/news/science-environment-46459714" target="_blank">one-way flight</a> from London to New York. If just one in five urban residents permanently changed their travel behavior in this way over the next few years, <a href="https://doi.org/10.1016/j.gloenvcha.2021.102224" target="_blank">we estimate</a> it would cut emissions from all car travel in Europe by about 8%.</p><p>Nearly half of the fall in <a href="https://www.nature.com/articles/s41558-020-0797-x" target="_blank">daily carbon emissions</a> during global lockdowns in 2020 came from reductions in transport emissions. The pandemic forced countries around the world to adapt to reduce the spread of the virus. In the UK, walking and cycling have been the big winners, with a <a href="https://www.creds.ac.uk/publications/at-a-crossroads-travel-adaptations-during-covid-19-restrictions-and-where-next/" target="_blank" rel="noopener noreferrer">20% rise</a> in people walking regularly, and cycling levels increasing by <a href="https://www.creds.ac.uk/wp-content/uploads/covid-transport-report.pdf" target="_blank" rel="noopener noreferrer">9% on weekdays and 58% on weekends</a> compared to pre-pandemic levels. This is despite cycle commuters being <a href="https://www.creds.ac.uk/wp-content/uploads/covid-transport-report.pdf" target="_blank" rel="noopener noreferrer">very likely to work from home</a>.</p><p>Active travel has offered an alternative to cars that keeps social distancing intact. It has helped people to stay safe during the pandemic and it could help reduce emissions as confinement is eased, particularly as the high prices of some electric vehicles are likely to put many potential buyers off for now.</p><p>So the race is on. Active travel can contribute to tackling the climate emergency earlier than electric vehicles while also providing affordable, reliable, clean, healthy and congestion-busting transportation.</p>

"The boardrooms of the world's largest banks are polluted to the core... How are we ever meant to stop the climate crisis if the world's most powerful decision-makers are in bed with the companies behind the wheel!?"
<p>That's how Bank on Our Future — a UK-based <a href="https://bankonourfuture.uk/about/" target="_blank">network</a> pressuring financial players to align their business practices with tackling the climate crisis — <a href="https://twitter.com/bankonourfuture/status/1379700128492175362" target="_blank">responded</a> Wednesday to a new DeSmog <a href="https://www.desmogblog.com/2021/04/06/revealed-climate-conflicted-directors-leading-the-worlds-top-banks/" target="_blank">analysis</a> revealing that a majority of directors at major banks worldwide are connected to polluting companies and organizations.</p><p>"This is a ginormous and superb piece of work by the talented sleuths" at DeSmog, <a href="https://twitter.com/brohannon6/status/1379708716937805826" target="_blank">said</a> Beau O'Sullivan, a campaigner at the Sunrise Project in Australia. He added that the report "contains findings that readers may find offensive and deeply disturbing."</p>
<div id="f462f" class="rm-shortcode" data-rm-shortcode-id="3050e0b6dade0e32a6d46bf4dec4f301"><blockquote class="twitter-tweet twitter-custom-tweet" data-twitter-tweet-id="1379860290188234762" data-partner="rebelmouse"><div style="margin:1em 0">Even a global #ClimateEmergency hasn't triggered rapid defunding of the industries responsible for driving climate… https://t.co/ogg5ZHjvRP</div> — Greenpeace Canada (@Greenpeace Canada)<a href="https://twitter.com/GreenpeaceCA/statuses/1379860290188234762">1617819304.0</a></blockquote></div>
<p>DeSmog examined the boards of 39 banks, including seven based in the United States, and found that 65% of directors have a total of 940 past or current ties to "climate-conflicted" industries. Across all banks studied, 16% of board members had ties to companies involved in extracting coal, gas, and oil.</p><p>In addition to fossil fuels, "there were also significant ties to banks and investment vehicles supporting polluting industries, as well as to thinktanks and lobbying groups with a history of campaigning against climate action," reported DeSmog's Phoebe Cooke, Rachel Sherrington, and Mat Hope.</p>

<p>"The fossil fuel industry has a well-established track record of ingratiating itself with society's opinion leaders and decision-makers," Geoffrey Supran, research associate in Harvard University's Department of the History of Science, told DeSmog about "the revolving doors between the corporate leaderships of incumbent industries."</p><p>"Having its fingers in all the pies allows the fossil fuel industry to quietly put its thumb on the scales of institutional decision-making, helping delay action, and protect the status quo," added Supran, who called the results of the analysis "predictable, yet shocking."</p>
<p>Alec Connon, coalition coordinator at <a href="https://www.commondreams.org/news/2020/01/09/climate-movement-takes-aim-wall-street-because-money-only-language-fossil-fuel" target="_blank">Stop the Money Pipeline</a>, responded similarly to the revelations in an email to Common Dreams.</p><p>"It should surprise no one that Wall Street boards are brimming with executives with close ties to climate-damaging companies," he said. "Since the Paris agreement was signed in 2015, Chase, Wells Fargo, and their Wall Street ilk have loaned more than $1 trillion to the fossil fuel industry. In the climate crisis, Wall Street is a primary villain."</p><p>"Perhaps if they had fewer fossil fuel executives on their boards," Connon added, "that would begin to change."</p>

<p>A coalition of green groups including the Rainforest Action Network (RAN) released a report last month <a href="https://www.commondreams.org/news/2021/03/24/60-largest-banks-have-dumped-38-trillion-fossil-fuels-2015-report-shows" target="_blank">detailing</a> how the world's 60 biggest banks have poured over $3.8 trillion into the fossil fuel industry in the wake of the landmark climate agreement, which aims to keep global temperature rise by 2100 to "well below" 2°C, with a more ambitious target of 1.5°C.</p><p>The groups' <em>Banking on Climate</em> report generated fresh criticism of big banks' recent <a href="https://www.commondreams.org/news/2021/03/08/wells-fargo-sets-new-financed-emissions-goal-climate-campaigners-warn-net-zero-not" target="_blank">pledges</a> to work toward net-zero greenhouse gas emissions by 2050. In light of DeSmog's reporting, Connon also addressed such commitments, saying that "2050 promises without 2021 action are essentially meaningless."</p><p>"We need action today, not vague promises of action in the next three decades," he continued. "Perhaps the fact that Wall Street boards are so full of fossil fuel executives is one reason why they're continuing to prioritize empty promises over immediate, meaningful policy change."</p>
<p>Since January 2020, the Stop the Money Pipeline coalition <a href="https://www.commondreams.org/news/2020/01/09/climate-movement-takes-aim-wall-street-because-money-only-language-fossil-fuel" target="_blank">has pressured</a> banks, insurers, and asset managers to cut ties with companies financing climate destruction. While its initial top targets were JPMorgan Chase, BlackRock, and Liberty Mutual, the coalition has expanded its efforts — including with a recently <a href="https://www.commondreams.org/news/2021/02/08/new-campaign-targets-wall-street-funding-stop-line-3-tar-sands-pipeline" target="_blank">launched</a> campaign directed at funders of Enbrige's Line 3 tar sands pipeline.</p><p>That controversial project — intensely <a href="https://www.commondreams.org/news/2021/03/08/climate-time-bomb-370-groups-urge-biden-immediately-halt-line-3-pipeline" target="_blank">opposed</a> by Indigenous water protectors and climate campaigners — was the focus of a <a href="https://www.theguardian.com/environment/2021/apr/06/banks-climate-change-line-3-pipeline-conflict-interest" target="_blank" rel="noopener noreferrer">report</a> by Emily Holden of Floodlight and Emily Atkin of HEATED, published Wednesday in The Guardian.</p><p>Citing DeSmog's finding that 77% of board members at seven major U.S. banks have ties to climate-conflicted companies or groups, the pair provided "an on-the-ground look at where all this dirty money is going," as Supran <a href="https://twitter.com/GeoffreySupran/status/1379799247600693250" target="_blank" rel="noopener noreferrer">put it</a>.</p>
<p>According to Holden and Atkin:</p><blockquote>From the U.S., Bank of America, Citigroup, JPMorgan Chase, and Wells Fargo have made the project possible with billions of dollars in loans, although it's impossible to tally precisely how much they have financed for the pipeline specifically. Another five large Canadian banks are also financing Enbridge, according to RAN.<br>Out of these nine North American banks backing Enbridge, six have recently published <a href="https://fortune.com/2021/03/09/wells-fargo-climate-carbon-neutral-net-zero/" target="_blank">net-zero climate goals</a>, pledging to align their investments with the international Paris climate agreement.<br>"The banks are gorging on doughnuts and then eating an apple afterwards," said Richard Brooks, the Toronto-based climate finance director for Stand.earth. "We certainly can't rely on banks or the private sector to lead us into climate safety and lead us toward emissions reductions. We need policy, we need regulation. We need government to act."</blockquote>

Fossil evidence indicates that the Amazon's plant life changed about 66 million years ago. Travelpix Ltd / Getty Images
About 66 million years ago, a 12-km asteroid struck Earth. The massive heat and impact likely triggered tidal waves and clouded the skies with ash, The Washington Post reported. Scientists estimate that up to 75 percent of all life on land went extinct, including the dinosaurs.
<p><br>The space rock that triggered that mass extinction event is also the likely reason we have the <a href="https://www.ecowatch.com/tag/amazon-rainforest" target="_self">Amazon Rainforest</a>, a new study suggests. Published in the prestigious journal <a href="https://science.sciencemag.org/content/372/6537/63" rel="noopener noreferrer" target="_blank">Science</a>, the research indicates that that same asteroid that killed the dinosaurs also birthed all of Earth's tropical <a href="https://www.ecowatch.com/tag/rainforests" target="_self">rainforests</a>.</p><p>"A global catastrophe involving a mass extinction <a href="https://www.ecowatch.com/antarctica-rainforest-dinosaurs-2645618791.html" target="_self">produces a different world</a>," wrote Bonnie F. Jacobs and Ellen D. Currano in an<a href="https://science.sciencemag.org/cgi/doi/10.1126/science.abh2086" rel="noopener noreferrer" target="_blank"> article</a> accompanying the study.</p><p>Mónica Carvalho, study co-author from the Smithsonian Tropical Research Institution (STRI) in Panama, examined tens of thousands of fossils in Columbia to understand how the plant life in Central and South America shifted from before and after the impact, reported <a href="https://nerdist.com/article/dinosaur-killing-asteroid-changed-earth-rainforests/" rel="noopener noreferrer" target="_blank">Nerdist</a>. Her team discovered that the type of vegetation comprising the continent's forests drastically changed from before and after. Before the crash, widely spaced conifers and ferns filled the region, allowing in large amounts of light, The Post reported.</p><p>After the asteroid struck, many species went extinct, particularly seed-bearing plants. Plant diversity declined about 45 percent after the impact, researchers found. Examining more than 50,000 fossil pollen records, the team discovered that flowering plants called angiosperms took over as the forests recovered during the next six million years. These filled in where other species had gone extinct, leading to the "reign of flowers," an <a href="https://stri.si.edu/story/flowers" rel="noopener noreferrer" target="_blank">STRI press release</a> noted.</p>

<p>The impact also changed the spatial structure of forests, from widely spaced to densely packed. Leaf data from more than 6,000 fossils shows that the thick, dense tropical canopy associated with today's rainforests did not develop until after the impact. The data suggests that the spatial change from "relatively open to closed and layered... led to increased vertical stratification and a larger diversity of plant growth forms," <a href="https://www.news18.com/news/buzz/the-same-asteroid-that-wiped-out-dinosaurs-may-have-led-to-creation-of-the-amazon-rainforest-3602573.html" rel="noopener noreferrer" target="_blank">News18</a> reported. As trees grew taller and closer, they partially blocked the sun, allowing different species of flowering plants to flourish, the Post reported. This is how Earth's most diverse terrestrial ecosystem — the tropical rainforests teeming with bright bromeliads and abundant orchids — developed, the study implies.</p><p>As for why, the researchers offered three theories: dinosaurs had kept the forest open and sparse by feeding on and trampling plants; falling ash enriched soils, giving an advantage to faster-growing flowering plants; and preferential extinction of conifers created the opportunity for flowering plants to take over.</p><p>While scientists aren't sure which theory, or combination of theories, created modern rainforests, Carvalho did conclude with one key takeaway: "The lesson learned here is that under rapid disturbances... tropical ecosystems do not just bounce back; they are replaced, and the process takes a really long time."</p>

<p>The shift in plant species and tree density likely also impacted the past and present climate, the STRI release added.

A new study of Greenland's glacial rivers has important implications for how scientists might model future ice melt and subsequent sea level rise.
<p>Previously, researchers thought they could measure ice melt simply by looking at the amount of meltwater sitting on top of <a href="https://www.ecowatch.com/tag/glaciers" target="_self">glaciers</a> and in moulins — shafts in the glacier that empty rivers from the surface to the interior, <a href="https://earther.gizmodo.com/hundreds-of-glacial-rivers-are-pouring-into-the-belly-o-1846627516" target="_blank">Earther explained</a>. But the new study, published in <a href="https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2020GL091418" target="_blank">Geophysical Research Letters</a> on Monday, found that a glacier's speed increased when water pressure rapidly changed beneath the ice sheet, <a href="https://www.nasa.gov/feature/goddard/2021/what-a-glacial-river-reveals-about-the-greenland-ice-sheet" target="_blank">NASA explained</a>.</p><p>"These findings will help to refine ice sliding models, which are critically important for predicting future ice sheet contributions to global sea level rise," Laurence Smith, study coauthor and Brown University environmental studies professor, told Earther.</p><p>The Greenland ice sheet is extremely important when it comes to global sea level rise. The size of Mexico, it currently contributes more to rising sea levels than any other source, NASA reported. If all of Greenland's ice sheet were to melt, it would increase water levels by 20 feet, according to Earther.</p><p>"The number one reason we are here is all about global sea level rise," Smith said in a video documenting the research. "Greenland is the single largest melting chunk of ice in the world. What really matters is how much of that water in the ice sheet gets out to the ocean."</p>
<span style="display:block;position:relative;padding-top:56.25%;" class="rm-shortcode" data-rm-shortcode-id="aecd51e2d4377acd514f0e348ea23554"><iframe lazy-loadable="true" src="https://www.youtube.com/embed/3twOCNP1Gdg?rel=0" width="100%" height="auto" frameborder="0" scrolling="no" style="position:absolute;top:0;left:0;width:100%;height:100%;"></iframe></span>
<p>To better understand the dynamics driving this melt, Smith and his team traveled to the Russell Glacier in southwestern Greenland in 2016 and studied a glacial river, NASA said. The researchers recorded the forward motion of the glacier itself, the amount of meltwater pouring into the moulin and the amount of meltwater pouring out from beneath the glacier at the water's edge. They determined that changes in subterranean water pressure were driving the glacier's overall speed.</p><p>"Even if the cavities are small, as long as the pressure is ramping up very fast, they will make the ice slide faster," Smith explained.</p><p>NASA Glaciologist Dr. Lauren Andrews compared a glacier moving over subterranean meltwater to car tires sliding on a wet road.</p><p>"If you have a rapid perturbation of water going into the subglacial system, you overwhelm the system, and so you create essentially a layer of water at the interface that's not contained in channels or cavities anymore," Andrews said.</p><p>The way that water pressure drives glacier speed had never been studied in the field before, NASA said. This new research now adds 168 hours of "rare in situ" measurements to understand the dynamics of glacial rivers, which had previously been overlooked.</p><p>"In 2015 when we started this study, there was surprisingly little attention paid to the hydrology of streams and rivers on the ice sheet, especially inland away from the ice edge, and we felt that this was a critical scientific gap," Smith said in the video.</p><p>The research supports the team's initial feeling.</p><p>"These findings affirm the importance of supraglacial rivers to subglacial water pressure and ice dynamics, even in relatively thick ice," the researchers wrote.</p>

By Kenny Stancil
The concentration of atmospheric carbon dioxide surged past 420 parts per million for the first time in recorded history this past weekend, according to a measurement taken at the Mauna Loa Observatory on the Big Island of Hawaii.
<p><br/></p>
<p>When the National Oceanic and Atmospheric Administration (NOAA) research station "began collecting CO2 measurements in the late 1950s, atmospheric CO2 concentration sat at around 315 PPM," the <em>Washington Post</em> <a href="https://www.washingtonpost.com/weather/2021/04/05/atmospheric-co2-concentration-record/" target="_blank" rel="noopener noreferrer">reported</a>. "On Saturday, the daily average was pegged at 421.21 PPM—the first time in human history that number has been so high."</p><p>Climate activist Greta Thunberg took notice of NOAA's most recent data on CO2 levels. She described the first-ever documented eclipse of 420 PPM of CO2 in Earth's atmosphere as "truly groundbreaking."</p>
<div id="a065c" class="rm-shortcode" data-rm-shortcode-id="119cbc41af39b702fc8cbfd0beb7c3b3"><blockquote class="twitter-tweet twitter-custom-tweet" data-twitter-tweet-id="1379021499651215360" data-partner="rebelmouse"><div style="margin:1em 0">Is this is confirmed, then it is truly groundbreaking to say the least.

<p>Exceeding 420 PPM of the heat-trapping gas "is a disconcerting milestone in the human-induced warming of the planet, around the halfway point on our path toward doubling preindustrial CO2 levels," the <em>Post</em> noted, adding:</p><blockquote>There is special significance in reaching and surpassing a concentration of 416 PPM. It means <a href="https://www.carbonbrief.org/met-office-atmospheric-co2-now-hitting-50-higher-than-pre-industrial-levels" target="_blank">we've passed the midpoint</a> between preindustrial CO2 levels, around 278 PPM, and a doubling of that figure, or 556 PPM.<br><br>The record of 421 PPM reached Saturday is just a single point and occurred as CO2 levels are nearing their yearly peak. But <a href="https://www.esrl.noaa.gov/gmd/webdata/ccgg/trends/co2_weekly_mlo.png" target="_blank" rel="noopener noreferrer">the levels over the past two months</a>, of more than 417 PPM, signal that the annual average concentration is likely to exceed 416 PPM.<br></blockquote><p>While the growing concentration of atmospheric CO2—which increases the global average temperature and the <a href="https://www.commondreams.org/news/2020/11/18/no-vaccine-climate-change-coronavirus-has-been-disastrous-says-red-cross-global" target="_blank" rel="noopener noreferrer">number and severity of extreme weather events</a>—is a long-term trend that corresponds with the rise of fossil fuel-powered capitalism, it has accelerated particularly rapidly since the 1970s.</p>

Wisconsin DNR fire crews battle a wildfire in Menomonee Falls that burned nearly 450 acres of marshland on Friday, and has since been contained. Wisconsin DNR / Marc Sass, DNR Cooperative Area Forest Ranger
Wisconsin Gov. Tony Evers declared a state of emergency on Monday due to heightened wildfire risk.
<p>The state's wildfire season got an early start thanks to an early snow melt, <a href="https://www.jsonline.com/story/news/local/wisconsin/2021/04/05/evers-issues-state-emergency-wildfires-blaze-across-wisconsin/7094810002/" target="_blank">the Milwaukee Journal Sentinel reported</a>. So far this year, more than 320 fires have scorched more than 1,500 acres, nearly reaching the total of 1,630.13 acres that were burned in all of 2020, according to the declaration.</p><p>"With nearly the entire state experiencing high or very high fire risk, protecting Wisconsinites from the destructive dangers of wildfires is a top priority," Evers said when announcing the order, according to the Milwaukee Journal Sentinel.</p><p>The emergency order gives the Wisconsin Department of Natural Resources (DNR), which usually handles firefighting in the state, additional resources. It will now receive support from other state agencies, as well as the Wisconsin National Guard and their Black Hawk helicopters, the DNR noted in a <a href="https://dnr.wisconsin.gov/newsroom/release/42726" target="_blank">press release</a>.</p><p>The announcement comes three days after brush fire erupted in Menomonee Falls, forcing some people to evacuate their homes, <a href="https://www.wisn.com/article/firefighters-battle-multiple-brush-fires-in-menomonee-falls/36017496#" rel="noopener noreferrer" target="_blank">WISN reported</a>. The fires burned 400 acres of marshland, the largest single burn so far this year, but luckily all of the homes were spared. Only a deer stand burned down.</p><p>However, the dry and windy conditions that fueled those fires are expected to persist in the state, leading Evers to declare an emergency.</p>
<p>"[B]ased upon weather predictions from the National Weather Service, Wisconsin will experience a period of warmer temperatures, lower humidity, and high winds that can quickly ignite wildland and create rapidly spreading fires," the order read.<br></p><p>Dry leaves and grass are also fueling the flames, the Milwaukee Journal Sentinel reported. The majority of counties are at high risk for fire, <a href="https://www.nbcnews.com/news/us-news/wisconsin-state-emergency-wildfire-risks-over-1-400-acres-already-n1263088" rel="noopener noreferrer" target="_blank">NBC News reported</a>, and the DNR has suspended annual burning permits while asking people to avoid setting fires.</p><p>"To help us keep Wisconsinites safe, the DNR is asking you to avoid all outdoor burning including limiting the use of campfires and making sure to extinguish and dispose of cigarettes properly," the DNR said in its press release.</p><p>While wildfires can occur in Wisconsin any time of the year, the primary season runs from March until May, <a href="https://www.nytimes.com/live/2021/04/06/us/wisconsin-wildfire" rel="noopener noreferrer" target="_blank">The New York Times reported</a>. The state's wildfire risk may also be increasing because of the <a href="https://www.ecowatch.com/climate-change/" target="_self">climate crisis</a>. The group Climate Power 2020 told the <a href="https://wisconsinexaminer.com/brief/climate-group-says-wisconsins-risk-of-wildfires-may-be-growing/#:~:text=Climate%20Power%202020%20also%20says,burned%205%2C768%20acres%20of%20land.&text=Climate%20change%20in%20Wisconsin%20is,keep%20the%20fire%20risks%20down." rel="noopener noreferrer" target="_blank">Wisconsin Examiner</a> that wildfires were becoming more common. While high humidity usually lessens fire risk, Wisconsin experienced two climate-related <a href="https://www.ecowatch.com/tag/drought" target="_self">droughts</a> between 2009 and 2016 that cost $45.9 billion in damages, and future droughts could increase fire danger.</p><p>Nationwide, the <a href="https://www.ecowatch.com/extreme-weather-climate-change-2647639196-2647639196.html" target="_blank">climate crisis is certainly driving fire risk</a>; 2020 alone brought a devastating wildfire season to the Western U.S., NBC noted. However, this spring wildfires have taken off in the Upper Plains, Rockies, Great Lakes and Southwest.</p><p>"Fire season can be at any time," Bureau of Land Management Spokesperson Carrie Bilbao told NBC News. "We just don't really have those wet seasons consistently anymore."</p>

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.
<p>But what's at the top of the list of concerns for those who study how climate change is unfolding – on <a href="https://www.dw.com/en/melting-ice-whats-the-big-deal/a-56872079" target="_blank">ice sheets</a> and urban street corners, in <a href="https://www.dw.com/en/oceans-key-to-solving-climate-crisis-say-world-leaders/a-55789573" target="_blank">oceans</a> and <a href="https://www.dw.com/en/how-climate-change-threatens-african-coffee-farmers/a-55648060" target="_blank">farm fields</a> – the climate scientists themselves?</p><p>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.</p><h2>The Greatest Unknown – People</h2><p>Nana Ama Browne Klutse <a href="https://www.researchgate.net/publication/348892571_The_Climatic_Analysis_of_Summer_Monsoon_Extreme_Precipitation_Events_over_West_Africa_in_CMIP6_Simulations" target="_blank">studies changing weather</a> 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.</p><p>"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."<span></span></p><p>Climate scientist Ruth Mottram studies the <a href="https://www.researchgate.net/publication/347619694_Higher_mass_loss_over_Greenland_and_Antarctic_ice_sheets_projected_in_CMIP6_than_CMIP5_by_high_resolution_regional_downscaling_EC-Earth" target="_blank">Greenland and Antarctic ice sheets</a> and sea level rise for the Danish Meteorological Institute, but it's not the science that worries her.</p><p>"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."</p><p>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.</p><p>"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.</p>
<h2>Protecting the Vulnerable<br></h2><p>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.</p><p>"We should remember that there are still some people living in the Arctic," he said. Around <a href="https://nsidc.org/cryosphere/arctic-meteorology/arctic-people.html" target="_blank" rel="noopener noreferrer">4 million people</a> in fact who would have to deal with the real-life consequences of solid ground <a href="https://www.nature.com/articles/s41467-018-07557-4" target="_blank" rel="noopener noreferrer">thawing beneath their feet and houses</a>. "Changes in these local or regional kind of climates and environments, they impact these people and some of these impacts could be very severe."</p><p>Closer to the planet's other pole, Carolina Vera fears that existing inequalities will only be <a href="https://www.dw.com/en/climate-change-hit-poorest-countries-hardest-in-2019/a-56334708" target="_blank">exacerbated by climate change</a>.</p><p>"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 <a href="https://www.nature.com/articles/d41586-018-06856-6" target="_blank">incorporate local knowledge and data collection into studies</a>, involving communities that are balancing the problems of deforestation with their need to farm.</p>
<h2>Heat and New Extremes</h2><p>Perhaps not surprisingly, <a href="https://www.dw.com/en/climate-change-hottest-november-ever/a-55842640" target="_blank" rel="noopener noreferrer">global heating</a> is a key concern for many researchers, like Dim Coumou, who studies extreme weather at Vrije Universiteit Amsterdam.</p><p>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 <a href="https://www.dw.com/en/pakistan-climate-migration-crisis/a-56126512" target="_blank" rel="noopener noreferrer">mass migration</a>.</p><p>But it's not just the tropics.</p><p>Closely related to heat is the increase in extreme weather brought on by a warming climate. Coumou and his colleagues' research shows how <a href="https://journals.ametsoc.org/view/journals/clim/aop/JCLI-D-20-0311.1/JCLI-D-20-0311.1.xml" target="_blank" rel="noopener noreferrer">changes to the jet stream will lead to more extreme weather in Europe</a>, including floods and droughts.</p><p>This increase in <a href="https://www.dw.com/en/climate-storms-cyclones-hurricanes-typhoons-explained/a-55521226" target="_blank">extreme weather</a> is climate scientist Abubakr Salih Babiker's biggest climate concern.</p><p>"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.

Despite the difficulties associated with the Covid-19 pandemic, the world added a record amount of new renewable energy capacity in 2020, according to data released Monday by the International Renewable Energy Agency.
<p>IRENA's annual <a href="https://www.irena.org/publications/2021/March/Renewable-Capacity-Statistics-2021" target="_blank">Renewable Capacity Statistics 2021</a> shows that global renewable energy capacity grew by more than 260 gigawatts (GW) last year, beating the previous record set in 2019 by nearly 50%. Last year marked the second consecutive year in which clean energy's share of all new generating capacity increased substantially, with renewables accounting for over 80% of all new electricity capacity added in 2020.</p><p>Total fossil fuel additions, by contrast, fell by more than 6% last year—from 64 GW worth of new electricity capacity in 2019 to 60 GW in 2020.</p><p>"These numbers tell a remarkable story of resilience and hope. Despite the challenges and the uncertainty of 2020, renewable energy emerged as a source of undeniable optimism for a better, more equitable, resilient, clean, and just future," IRENA Director-General Francesco La Camera said in a statement.</p><p>"The great reset," as La Camera called the coronavirus-driven economic slowdown, "offered a moment of reflection and chance to align our trajectory with the path to inclusive prosperity, and there are signs we are grasping it."</p>

<p>While La Camera described the widespread adoption of renewable energy sources as an "unstoppable" trend, he also emphasized that "there is a huge amount to be done."</p><p>Notwithstanding recent momentum in favor of clean energy, La Camera said that in order to limit global temperature rise to 1.5ºC, "significant planned energy investments must be redirected to support the transition if we are to achieve 2050 goals" of net zero greenhouse gas (GHG) emissions, as outlined last month in IRENA's<a href="https://irena.org/publications/2021/March/World-Energy-Transitions-Outlook" target="_blank"> World Energy Transition Outlook</a>.</p><p>La Camera's words of caution about the inadequate pace of the global energy transformation echoes a recent warning by Fatih Bitrol, executive director of the International Energy Agency, who <a href="https://www.commondreams.org/news/2021/04/01/people-worldwide-said-build-back-better-iea-chief-says-just-opposite-happening" target="_blank" rel="noopener noreferrer">said</a> last week that even though the world's biggest economies have pledged to achieve net zero GHG emissions by mid-century, few have implemented the policies necessary to realize that objective.</p><p>Regarding the worldwide expansion of renewable energy capacity in 2020, La Camera stressed that "in this critical decade of action, the international community must look to this trend as a source of inspiration to go further."</p>
