Why East Antarctica is a ‘sleeping giant’ of sea level rise

Why East Antarctica is a ‘sleeping giant’ of sea level rise

BBC Future reports: Jan Lieser had just started going through the dozens of satellite images he looks at every day when he realised something was missing. As a glaciologist at the University of Tasmania’s Institute for Marine and Antarctic Studies, he knew the shape of every ice shelf sticking out from the coast of East Antarctica. And on 17 March 2022, there was a gap where most of the Conger glacier’s ice shelf had broken off into an iceberg the…

As bank failures dominate news, Biden administration approves huge Alaska oil project

As bank failures dominate news, Biden administration approves huge Alaska oil project

The New York Times reports: The Biden administration gave formal approval Monday for a huge oil drilling project in Alaska known as Willow, despite widespread opposition because of its likely environmental and climate impacts. The president is also expected to announce sweeping restrictions on offshore oil leasing in the Arctic Ocean and across Alaska’s North Slope in an apparent effort to temper criticism over the Willow decision and, as one administration official put it, to form a “firewall” to limit…

Climate is changing too quickly for the Sierra Nevada’s ‘zombie forests’

Climate is changing too quickly for the Sierra Nevada’s ‘zombie forests’

NPR reports: Some of the tall, stately trees that have grown up in California’s Sierra Nevada are no longer compatible with the climate they live in, new research has shown. Hotter, drier conditions driven by climate change in the mountain range have made certain regions once hospitable to conifers — such as sequoia, ponderosa pine and Douglas fir — an environmental mismatch for the cone-bearing trees. “They were exactly where we expected them to be, kind of along the lower-elevation,…

How single-celled yeasts are doing the work of 1,500-pound cows

How single-celled yeasts are doing the work of 1,500-pound cows

The Washington Post reports: The first course was a celery root soup lush with whole milk. The last was a spice cake topped with maple cream cheese frosting served with a side of ice cream. And then a latte with its fat cap of glossy foam. In all, a delicious lunch. Maybe a little heavy on the dairy. Only this dairy was different. It was not the product of a cow or soybean or nut. The main ingredient of this…

Does President Biden mean what he says on climate?

Does President Biden mean what he says on climate?

Abigail Dillen writes: In his recent State of the Union address, President Biden acknowledged the “existential threat” posed by climate change, citing an obligation to our children and grandchildren to confront it. Now, his administration is about to test its fidelity to that obligation. It will soon decide whether to approve a major drilling project in Alaska that could pump 280 million tons of greenhouse gases into the atmosphere, derailing the administration’s ability to meet its own climate commitments. The Biden administration has set the most…

White House denies reports that Alaska oil drilling project has been approved

White House denies reports that Alaska oil drilling project has been approved

The Guardian reports: The Biden administration has denied reports that it has authorized a key oil drilling project on Alaska’s north slope, a highly contentious project that environmentalists argue would damage a pristine wilderness and gut White House commitments to combat climate crisis. Late Friday, Bloomberg was first to report citing anonymous sources that senior Biden advisers had signed off on the project and formal approval would be made public by the Interior Department next week. The decision to authorize…

The creeping threat of the Great Atlantic Sargassum Belt

The creeping threat of the Great Atlantic Sargassum Belt

The Guardian reports: Seaweed has been having a moment. Eco-influencers and columnists rave about its benefits, in everything from beauty products to biofuels. Jamie Oliver has embraced it as a recipe ingredient; Victoria Beckham uses it to keep off the pounds. And they’re right: seaweed is packed with nutrition, it sucks up carbon and is an amazingly versatile addition to the green economy. But one type of seaweed is not a benign force. Vast fields of sargassum, a brown seaweed,…

How wildfires deplete the Earth’s ozone layer

How wildfires deplete the Earth’s ozone layer

Carolyn Gramling writes: Towering clouds of smoke sent into the stratosphere by ferocious wildfires can eat away at Earth’s ozone layer thanks to a potent mix of smoke, atmospheric chemistry and ultraviolet light, a new study finds. During late 2019 and early 2020, Australia’s skies turned black, darkened by thick columns of wildfire smoke that reached into the stratosphere. In the aftermath, satellite data revealed that the smoke was somehow reacting with atmospheric molecules to eat away at Earth’s ozone…

Biden admin paradox: Boost oil — and cut CO2?

Biden admin paradox: Boost oil — and cut CO2?

E&E News reports: The Biden administration’s seemingly contradictory energy and climate strategy was on full display here Wednesday: Try to pivot away from fossil fuels, but promote them for now. Energy Secretary Jennifer Granholm faced that paradox as she addressed energy leaders and insiders gathered in a hotel ballroom, praising the uptick in U.S. oil and gas exports during Russia’s war in Ukraine while touting a clean energy shift. “Europe is poised to reach the spring without major outages or…

1,000 super-emitting methane leaks risk triggering climate tipping points

1,000 super-emitting methane leaks risk triggering climate tipping points

The Guardian reports: More than 1,000 “super-emitter” sites gushed the potent greenhouse gas methane into the global atmosphere in 2022, the Guardian can reveal, mostly from oil and gas facilities. The worst single leak spewed the pollution at a rate equivalent to 67m running cars. Separate data also reveals 55 “methane bombs” around the world – fossil fuel extraction sites where gas leaks alone from future production would release levels of methane equivalent to 30 years of all US greenhouse…

Climate impacts have made human-wildlife conflicts a global problem

Climate impacts have made human-wildlife conflicts a global problem

Inside Climate News reports: Climate change is driving more conflicts between humans and wildlife, as expanding development, deepening drought and quickly changing ecosystems force animals and people into new territories where they’re more likely to encounter each other, a new study says. Experts have long called for a concerted effort to address these human-wildlife clashes, which can lead to property damage, as well as injuries and death for both humans and animals. In fact, human-wildlife conflicts are already the leading…

Solar geoengineering should be regulated, UN report says

Solar geoengineering should be regulated, UN report says

E&E News reports: A panel of climate experts convened by the United Nations is calling for international regulations to extend into the stratosphere. The recommendation — detailed in a report released Monday — could help manage the risks associated with spraying sunlight-reflecting aerosols dozens of miles above the Earth’s surface. Such stratospheric aerosol injection is largely untested and potentially harmful, but it’s attracting attention as an emergency measure to avoid catastrophic climate change. “This group unanimously suggests [stratospheric aerosol injection]…

Ants aren’t adapting to warmer temperatures

Ants aren’t adapting to warmer temperatures

Eos reports: Ants are a bedrock of forest ecosystems, and they might not be adjusting well to warming temperatures. In newly published research, scientists found that foraging ants preferred to gather food placed at specific temperatures but did not avoid food that was too hot or too cold. Long-term exposure to these hot, but sublethal, temperatures could be changing the ants’ food and energy usage, harming colonies and broader forest ecosystems. Hotter temperatures force ants to use more energy to…

Warming seas are carving into glacier that could trigger major sea level rise

Warming seas are carving into glacier that could trigger major sea level rise

The Washington Post reports: Rapidly warming oceans are cutting into the underside of the Earth’s widest glacier, startling new data and images show, leaving the ice more prone to fracturing and ultimately heightening the risk for major sea level rise. Using an underwater robot at Thwaites Glacier, researchers have determined that warm water is getting channeled into crevasses in what the researchers called “terraces” — essentially, upside-down trenches — and carving out gaps under the ice. As the ice then…
