Climate news that has caught our attention.
At Least 85% of the World’s Population Lives in Areas Affected by Climate Change. The Washington Post (paywall) has details: “At least 85 percent of the global population has experienced weather events made worse by climate change, according to research published Monday in the journal Nature Climate Change. After using machine learning to analyze and map more than 100,000 studies of events that could be linked to global warming, researchers paired the analysis with a well-established data set of temperature and precipitation shifts caused by fossil fuel use and other sources of carbon emissions. These combined findings — which focused on events such as crop failures, floods and heat waves — allowed scientists to make a solid link between escalating extremes and human activities. They concluded that global warming has affected 80 percent of the world’s land area…”
Deadly Heat is Baking Cities. Here’s How to Cool Them Down. WIRED.com (paywall) takes a look at the leading weather-related cause of death in the US: “…As global temperatures rapidly climb, scientists, governments, and activists are scrambling for ways to counter the heat island effect. According to the World Health Organization, the number of people exposed to heat waves jumped by 125 million between 2000 and 2016. Extreme heat kills more Americans than any other natural disaster, and is especially dangerous for folks with preexisting conditions like asthma. By 2050, seven in 10 people will live in cities, says the World Bank. That will be a whole lot of sweltering humans. “I really see cities as kind of a canary in the coal mine type of situation, where you have a little bit of a harbinger of what the rest of the planet could be experiencing,” says Portland State University climate adaptation scientist Vivek Shandas, who has studied the heat island effect in over 50 US cities...”
Climate Scientists Created a SWAT Team for Weather Disasters. Bloomberg Green has the story; here’s an excerpt: “When weather disaster strikes, observers near and far ask the same question: Climate change—is it or isn’t it? The simplest answer, yes, lacks specificity. All weather is a joint human-nature venture, because we’ve made the atmosphere hotter than it’s been in 125,000 years. Disasters are nothing new. Assigning blame for them is. A breakthrough out of the U.K. is providing better, more nuanced answers faster with powerful implications for citizens, first responders, and the media. Friederike Otto is at the heart of it. Otto is a climate scientist at Imperial College London and co-leader of World Weather Attribution, a research collaboration that quickly analyzes if or how climate change has made extreme weather somehow worse—more intense, more likely, or deadlier. It’s a small, nimble, and—because of a current lack of funding—mostly volunteer effort assembled to bust science out of the academic quad and let a curious public know when climate change affects them in the most direct and personal way...”
Picturing Our Future. How will steadily rising seas impact coastal cities and future development and conservation efforts. Climate Central takes a look with an amazing series that pictures how encroaching water will impact major metropolitan areas around the world: “About 50 major cities around the world are at risk of losing most of their developed areas to unremitting sea level rise over the next century and beyond. New research from Climate Central scientists, in collaboration with others from Princeton University and the Potsdam Institute for Climate Impact Research in Germany, shows that nations will need to mount globally unprecedented defenses to protect populations in these areas under the 3°C emissions pathway. The peer-reviewed research has enabled Climate Central to develop Picturing Our Future, a collection of powerful visual tools to communicate the future risks of warming and to show what we can save...”
Major Climate Action at Stake in Fight Over Twin Bills Pending in Congress. Here is an excerpt from an analysis at The New York Times (paywall): “…Mr. Biden’s plan to try to fortify the United States against extreme weather — and cut the carbon dioxide emissions that are heating the Earth and fueling disasters — is embedded in two pieces of legislation pending on Capitol Hill. The future of both bills remains in question, with tension between moderate and progressive Democrats over the size and scope of many details. Together, they contain what would be the most significant climate action ever taken by the United States. Because Democrats could lose control of Congress after 2022 and Republicans have shown little interest in climate legislation, it could be years before another opportunity arises — a delay that scientists say the planet cannot afford. The climate provisions are designed to quickly transform energy and transportation, the country’s two largest sources of greenhouse gases, from systems that now mostly burn gas, oil and coal to sectors that run increasingly on clean energy from the sun, wind and nuclear power…”
Fossil Fuel Industry Gets Subsides of $11 Million a Minute, IMF Finds. The Guardian reports: “The fossil fuel industry benefits from subsidies of $11m every minute, according to analysis by the International Monetary Fund. The IMF found the production and burning of coal, oil and gas was subsidized by $5.9tn in 2020, with not a single country pricing all its fuels sufficiently to reflect their full supply and environmental costs. Experts said the subsidies were “adding fuel to the fire” of the climate crisis, at a time when rapid reductions in carbon emissions were urgently needed. Explicit subsidies that cut fuel prices accounted for 8% of the total and tax breaks another 6%. The biggest factors were failing to make polluters pay for the deaths and poor health caused by air pollution (42%) and for the heatwaves and other impacts of global heating (29%).
Extreme Heat is One of the Deadliest Consequences of Climate Change. Here’s a clip from an analysis at The Los Angeles Times: “…Extreme heat is one of the deadliest consequences of global warming. But in a state that prides itself as a climate leader, California chronically undercounts the death toll and has failed to address the growing threat of heat-related illness and death, according to a Los Angeles Times investigation. Between 2010 and 2019, the hottest decade on record, California’s official data from death certificates attributed 599 deaths to heat exposure. But a Times analysis found that the true toll is probably six times higher. An examination of mortality data from this period shows that thousands more people died on extremely hot days than would have been typical during milder weather. All told, the analysis estimates that extreme heat caused about 3,900 deaths…”
Increasing Heat and Rainfall Extremes Now Far Outside the Historical Climate. Here’s a summary of new research at NPJ Climate and Atmospheric Science: “Over the last decade, the world warmed by 0.25 °C, in-line with the roughly linear trend since the 1970s. Here we present updated analyses showing that this seemingly small shift has led to the emergence of heat extremes that would be virtually impossible without anthropogenic global warming. Also, record rainfall extremes have continued to increase worldwide and, on average, 1 in 4 rainfall records in the last decade can be attributed to climate change. Tropical regions, comprised of vulnerable countries that typically contributed least to anthropogenic climate change, continue to see the strongest increase in extremes…”
6 Aspects of American Life Threatened by Climate Change. The New York Times (paywall) has perspective: “Less food. More traffic accidents. Extreme weather hitting nuclear waste sites. Migrants rushing toward the United States, fleeing even worse calamity in their own countries. Those scenarios, once the stuff of dystopian fiction, are now driving American policymaking. Under orders from President Biden, top officials at every government agency have spent months considering the top climate threats their agencies face, and how to cope with them. On Thursday, the White House offered a first look at the results, releasing the climate-adaptation plans of 23 agencies, including the departments of Energy, Defense, Agriculture, Homeland Security, Transportation and Commerce. The plans reveal the dangers posed by a warming planet to every aspect of American life, and the difficulty of coping with those threats...”
Google, YouTube to Prohibit Ads and Monetization on Climate Denial Content. Axios explains: “Google and YouTube on Thursday announced a new policy that prohibits climate deniers from being able to monetize their content on its platforms via ads or creator payments. It’s one of the most aggressive measures any major tech platform has taken to combat climate change misinformation. Google advertisers and publishers, as well as YouTube creators, will be prohibited from making ad revenue off content that contradicts “well-established scientific consensus around the existence and causes of climate change,” the company’s ads team said in a statement. “This includes content referring to climate change as a hoax or a scam, claims denying that long-term trends show the global climate is warming, and claims denying that greenhouse gas emissions or human activity contribute to climate change…”
Climate Journalism is Coming of Age. The Nation has details: “It’s taken too long, but the mainstream media—finally and haltingly—seems to be realizing that the climate crisis is a story that can no longer be ignored. Until a couple years ago, many of the world’s most influential news organizations, especially in the United States, relegated the climate story to the fringe. What we have called “climate silence” prevailed. How far we have come. Today, it’s not unusual to see a climate story every day or two on the front page of The Washington Post or The New York Times, where Sarah Kaplan, Somini Sengupta, and Hiroko Tabuchi, among others, do exceptional reporting. TV networks, long the laggards in climate reporting, are also joining in, especially in their morning newscasts, where weather experts Al Roker at NBC, Jeff Berardelli at CBS, and Ginger Zee at ABC talk often about what they don’t hesitate to call “the climate crisis” or even “the climate emergency.” CNN, NPR, the Los Angeles Times, and other major outlets are hiring reporters, editors, producers, and more to staff new or expanding climate units…”
The (Very Slow) Race to Move Forests in Time to Save Them. WIRED.com collaborated with Mother Jones on this story – here’s an excerpt: “…The future of forests is a grim one—too grim for some of us to bear. By 2030, 75 percent of redwoods will disappear from some of their coastal California habitats. In some climate scenarios, almost none of the namesake species in Joshua Tree National Park will exist. Sea level change is creating ghost forests all along the Eastern Seaboard—already, less than a third of New Jersey’s Atlantic white cedar habitat remains. Like humans, forests have always migrated for their survival, with new trees growing in more hospitable directions and older trees dying where they are no longer best suited to live. The problem now is that they simply can’t move fast enough. The average forest migrates at a rate of roughly 1,640 feet each year, but to outrun climate change, it must move approximately 9,800 to 16,000 feet—up to 10 times as fast...”
