2021’s climate disasters revealed an east-west weather divide

2021’s climate disasters revealed an east-west weather divide

Wildfires that swept through Sequoia National Forest in California in September 2021 were so severe they killed ancient trees that had adapted to survive fires. AP Photo/Noah Berger By Shuang-Ye Wu, University of Dayton Alongside a lingering global pandemic, the year 2021 was filled with climate disasters, some so intense they surprised even the scientists who study them. Extreme rainstorms turned to raging flash floods that swept through mountain towns in Europe, killing over 200 people. Across Asia, excessive rainfall…

How will our warming climate stabilize? Scientists look to the distant past

How will our warming climate stabilize? Scientists look to the distant past

Ars Technica reports: Thanks to unbridled greenhouse gas emissions, our planet is stitching together a climate version of Dr. Frankenstein’s monster. We still have ice from the warmer parts of the Pleistocene even as our temperature approaches the warmer Pliocene levels of 3 million years ago. Meanwhile, our CO2 level is between the Pliocene and the Miocene of 10 million years ago, and we risk an Eocene hothouse not seen in 40 million years. At some point, this unnatural fusion…

Behind Manchin’s opposition, a long history of fighting measures for tackling climate change

Behind Manchin’s opposition, a long history of fighting measures for tackling climate change

The New York Times reports: Senator Joe Manchin III on Monday cited a litany of issues that drove him to oppose President Biden’s $2 trillion Build Back Better bill, from Democrats’ refusal to attach work requirements to social benefits to their failure to raise tax rates on the rich. But left almost unsaid was the issue that has always propelled his political career as a Democratic maverick: climate change. The version of the bill that passed the House last month…

Coal in America: A legacy of environmental catastrophe

Coal in America: A legacy of environmental catastrophe

James Bruggers writes: Along the winding, two lane road that leads to Tracy Neece’s mountain in Floyd County, Kentucky, there’s no hint of the huge scars in the hills beyond the oaks and the pines. Green forests cover steep slopes on each side of the road, which turns from blacktop to dusty gravel. Modest homes are nestled into the bottomlands along a creek with gardens that grow corn and zucchini under a hot summer sun. The first sign of the…

A relentless assault on the Amazon rainforest poses a threat to the planet

A relentless assault on the Amazon rainforest poses a threat to the planet

Georgina Gustin writes: The Amazon is enveloping and lush, a place of stupefying richness. But a powerful web of extractive forces is also at work here. Every day, thousands of miners, loggers, farmers and ranchers burn or cut roughly 10,000 acres of forest, working to satisfy a growing demand for the resources it contains. They are tiny cogs in a sprawling global machine that has destroyed nearly one-fifth of the Brazilian rainforest—an area about the size of California—over the last…

Global warming can set the stage for deadly tornadoes

Global warming can set the stage for deadly tornadoes

Inside Climate News reports: Adding a grim exclamation point to a year of deadly climate extremes, the early December tornadoes that killed at least 90 people in the Southeast were some of the most intense storms on record so late in the year. The storms fired up in Arkansas the night of Dec. 10, during weather far too hot and humid for the season, and raced across Missouri, Illinois, Tennessee and Kentucky on Dec. 11. It will take weeks of…

2021 Arctic Report Card reveals a (human) story of cascading disruptions, extreme events and global connections

2021 Arctic Report Card reveals a (human) story of cascading disruptions, extreme events and global connections

Community members from Utqiagvik, Alaska, look to open water from the edge of shorefast sea ice. Matthew Druckenmiller By Matthew Druckenmiller, University of Colorado Boulder; Rick Thoman, University of Alaska Fairbanks, and Twila Moon, University of Colorado Boulder The Arctic has long been portrayed as a distant end-of-the-Earth place, disconnected from everyday common experience. But as the planet rapidly warms, what happens in this icy region, where temperatures are rising twice as fast as the rest of the globe, increasingly…

New York City’s gas ban takes fight against climate change to the kitchen

New York City’s gas ban takes fight against climate change to the kitchen

The New York Times reports: New York City is set to ban gas-powered stoves, space heaters and water boilers in all new buildings, a move that would significantly affect real estate development and construction in the nation’s largest city and could influence how cities around the world seek to reduce the burning of fossil fuels, which drives climate change. The City Council is expected on Wednesday to approve a bill banning gas hookups in new buildings — effectively requiring all-electric…

Antarctica’s Thwaites Glacier ice shelf could collapse within five years

Antarctica’s Thwaites Glacier ice shelf could collapse within five years

Science News reports: The demise of a West Antarctic glacier poses the world’s biggest threat to raise sea levels before 2100 — and an ice shelf that’s holding it back from the sea could collapse within three to five years, scientists reported December 13 at the American Geophysical Union’s fall meeting in New Orleans. Thwaites Glacier is “one of the largest, highest glaciers in Antarctica — it’s huge,” Ted Scambos, a glaciologist at the Boulder, Colo.–based Cooperative Institute for Research…

When did scientists first warn humanity about climate change?

When did scientists first warn humanity about climate change?

Live Science reports: Climate change warnings are coming thick and fast from scientists; thousands have signed a paper stating that ignoring climate change would yield “untold suffering” for humanity, and more than 99% of scientific papers agree that humans are the cause. But climate change wasn’t always on everyone’s radar. So when did humans first become aware of climate change and the dangers it poses? Scientists first began to worry about climate change toward the end of the 1950s, Spencer…

A PR giant is caught between climate pledges and fossil fuel clients

A PR giant is caught between climate pledges and fossil fuel clients

The New York Times reports: After last month’s United Nations-sponsored environmental conference in Glasgow, the public relations giant Edelman praised the participants for reaching “a new level of international consensus that climate change is an existential threat to humanity.” In a statement posted on its website, Edelman also called for “more scrutiny on corporate climate lobbying efforts” and argued that many of the pledges that resulted from the conference “fall far short of what is necessary to avert global climate…

How the oil and gas industry rigs the system to keep winning

How the oil and gas industry rigs the system to keep winning

Naomi Oreskes and Jeff Nesbit write: Despite countless investigations, lawsuits, social shaming, and regulations dating back decades, the oil and gas industry remains formidable. After all, it has made consuming its products seem like a human necessity. It has confused the public about climate science, bought the eternal gratitude of one of America’s two main political parties, and repeatedly out-maneuvered regulatory efforts. And it has done all this in part by thinking ahead and then acting ruthlessly. While the rest…

Carbon inheritance

Carbon inheritance

James Balog writes: Do any of us really have a right to be angry or frustrated about the climate- and-energy crisis without considering how we ourselves have contributed to it? Honestly? Truly? With eyes wide open? I don’t think so. We all play a role in producing the problem. No one inhabits a righteous, pure-and-holy aerie above the human condition. Not me, not you, not anybody. We all drive our chariots of carbon fire. We all rely on carbon fuels…

A billion shellfish and other marine animals baked to death

Julia Rosen writes: During this summer’s stifling heat wave, Robin Fales patrolled the same sweep of shore on Washington’s San Juan Island every day at low tide. The stench of rotting sea life grew as temperatures edged toward triple digits—roughly 30 degrees above average—and Fales watched the beds of kelp she studies wilt and fade. “They were bleaching more than I had ever seen,” recalls Fales, a Ph.D. candidate and marine ecologist at the University of Washington. She didn’t know…

Snow may vanish for years at a time in Mountain West with climate warming

Snow may vanish for years at a time in Mountain West with climate warming

The Washington Post reports: A new study provides a glimpse into the future of Western U.S. snow and the picture is far from rosy: In about 35 to 60 years, mountainous states are projected to be nearly snowless for years at a time if greenhouse gas emissions continue unchecked and climate change does not slow. Due to rising temperatures, the region has already lost 20 percent of its snowpack since the 1950s. That’s enough water to fill Lake Mead, the…
