What the end-Triassic mass extinction tells us about our planet’s current condition

What the end-Triassic mass extinction tells us about our planet’s current condition

Ars Technica reports: The end-Triassic extinction, which happened 201 million years ago, was Earth’s third most severe extinction event since the dawn of animal life. Like today, CO2 rise and global warming were present, but the similarities don’t end there. As with today, it was a time of wildfires, deforestation, downpours, erosion, ocean acidification, marine dead zones, vanishing coral reefs, sea-level rise, and even insect plagues. There was also pollution by mercury, sulfur dioxide, halocarbons, and methane—and possibly even a…

Atlanta shooting part of alarming U.S. crackdown on environmental defenders

Atlanta shooting part of alarming U.S. crackdown on environmental defenders

The Guardian reports: The shooting of Manuel Esteban Paez Terán, believed to be the first environmental defender killed in the US, is the culmination of a dangerous escalation in the criminalization and repression of those who seek to protect natural resources in America, campaigners have warned. The death of the 26-year-old, who was also known as “Tortuguita” or “Little Turtle,” in a forest on the fringes of Atlanta was the sort of deadly act “people who have been paying attention…

Melting Alaska wants to drill more oil

Melting Alaska wants to drill more oil

Bill McKibben writes: If you wanted an example of the reason we’re still losing the fight to slow the earth’s heating, the proposed Willow oil project in Alaska should suffice. This should be the no-brainer of all time. The ConocoPhillips plan for a massive new oil field development flies in the face of all climate science and reason. It would be producing huge quantities of oil for at least the next three decades—long past the point when scientists say we…

Microplastics are filling the skies. Will they affect the climate?

Microplastics are filling the skies. Will they affect the climate?

Nicola Jones writes: Plastic has become an obvious pollutant over recent decades, choking turtles and seabirds, clogging up our landfills and waterways. But in just the past few years, a less-obvious problem has emerged. Researchers are starting to get concerned about how tiny bits of plastic in the air, lofted into the skies from seafoam bubbles or spinning tires on the highway, might potentially change our future climate. “Here’s something that people just didn’t think about — another aspect of…

Native seed banks in the U.S. have insufficient supplies to mitigate the effects of climate change

Native seed banks in the U.S. have insufficient supplies to mitigate the effects of climate change

NPR reports: In the wake of wildfires, floods and droughts, restoring damaged landscapes and habitats requires native seeds. The U.S. doesn’t have enough, according to a report released Thursday. “Time is of the essence to bank the seeds and the genetic diversity our lands hold,” the National Academies of Sciences, Engineering and Medicine (NASEM) report said. As climate change worsens extreme weather events, the damage left behind by those events will become more severe. That, in turn, will create greater…

Elephants, the gardeners of Africa’s rainforests, play a vital role in promoting carbon retention

Elephants, the gardeners of Africa’s rainforests, play a vital role in promoting carbon retention

Anthropocene magazine reports: Elephants been called a lot of things: the world’s largest land creatures, imperiled, majestic, charismatic. Now scientists have a few more terms for describing them: foresters and climate champions. In the jungles of equatorial Africa, scientists report that forest elephants play an important role in shaping the forest around them as they vacuum up as much as 200 kilograms worth of plants every day. Their appetites influence not just what trees survive but how much carbon the…

Could independents upend U.S. climate politics?

Could independents upend U.S. climate politics?

Alexander Burns writes: A small band of political strategists gathered last September in a restaurant near Dupont Circle to meet a visitor from the other side of the world. Everyone at the table was immersed in the battle against climate change; nearly all had been involved in passing the Inflation Reduction Act, the clean-energy law Democrats enacted over the summer. Their guest was Byron Fay, an Australian operative who had arrived in Washington with an exotic political scheme in mind….

How wind, sun and water can power the world

How wind, sun and water can power the world

The Guardian reports: “Combustion is the problem – when you’re continuing to burn something, that’s not solving the problem,” says Prof Mark Jacobson. The Stanford University academic has a compelling pitch: the world can rapidly get 100% of its energy from renewable sources with, as the title of his new book says, “no miracles needed”. Wind, water and solar can provide plentiful and cheap power, he argues, ending the carbon emissions driving the climate crisis, slashing deadly air pollution and…

Changing the language of climate change

Changing the language of climate change

Scientific American reports: Climate change is already disrupting the lives of billions of people. What was once considered a problem for the future is raging all around us right now. This reality has helped convince a majority of the public that we must act to limit the suffering. In an August 2022 survey by the Pew Research Center, 71 percent of Americans said they had experienced at least one heat wave, flood, drought or wildfire in the past year. Among…

An ancient farming technique could stabilize crop yields under changing conditions

An ancient farming technique could stabilize crop yields under changing conditions

Science Alert reports: As climates around the world grow harsher and increasingly unpredictable, concerns are increasing over our world’s food security. Already, yields of staple crops like maize and wheat are dropping in low-latitude tropical regions and in dry and drying regions such as African drylands and parts of the Mediterranean. Wealthy countries are far from immune. Australia experienced almost a 30 percent crop yield decline between 1990 and 2015 due to reduced rainfall. While studying food diversity in 2011,…

Forests managed by Indigenous peoples are some of the Amazon’s last remaining carbon sinks

Forests managed by Indigenous peoples are some of the Amazon’s last remaining carbon sinks

Inside Climate News reports: Forests managed by Indigenous peoples and other local communities in the Amazon region draw vast amounts of planet-warming carbon dioxide out of the atmosphere while the rest of the rainforest has become a net source of the greenhouse gas, a new report has found. The discrepancy results from differences in deforestation rates between the two types of land. The study from the World Resources Institute, a nonprofit global research organization focused on solving environmental challenges, adds…

Warning of unprecedented heatwaves as El Niño set to return in 2023

Warning of unprecedented heatwaves as El Niño set to return in 2023

The Guardian reports: The return of the El Niño climate phenomenon later this year will cause global temperatures to rise “off the chart” and deliver unprecedented heatwaves, scientists have warned. Early forecasts suggest El Niño will return later in 2023, exacerbating extreme weather around the globe and making it “very likely” the world will exceed 1.5C of warming. The hottest year in recorded history, 2016, was driven by a major El Niño. It is part of a natural oscillation driven…

Europe is winning the energy war with Putin, but food prices are likely to rise

Europe is winning the energy war with Putin, but food prices are likely to rise

Politico reports: Halfway through the first winter of Europe’s energy war with Russia, only one side is winning. When Vladimir Putin warned in September that Europeans would “freeze” if the West stuck to its energy sanctions against Russia, Moscow’s fossil fuel blackmail appeared to be going exactly to plan. European wholesale gas prices were north of €200 per megawatt hour, around 10 times higher than they had been for most of 2021. Plans were drawn up to cut gas demand…

Exxon knew: Its scientists predicted global warming, even as company cast doubts, study finds

The New York Times reports: In the late 1970s, scientists at Exxon fitted one of the company’s supertankers with state-of-the-art equipment to measure carbon dioxide in the ocean and in the air, an early example of substantial research the oil giant conducted into the science of climate change. A new study published Thursday in the journal Science found that over the next decades, Exxon’s scientists made remarkably accurate projections of just how much burning fossil fuels would warm the planet….
