Climate emissions shrinking the stratosphere, scientists reveal

Climate emissions shrinking the stratosphere, scientists reveal

The Guardian reports: Humanity’s enormous emissions of greenhouse gases are shrinking the stratosphere, a new study has revealed. The thickness of the atmospheric layer has contracted by 400 metres since the 1980s, the researchers found, and will thin by about another kilometre by 2080 without major cuts in emissions. The changes have the potential to affect satellite operations, the GPS navigation system and radio communications. The discovery is the latest to show the profound impact of humans on the planet….

It’s time to kick gas

It’s time to kick gas

Bill McKibben writes: We’re used to the idea that CO2—one carbon atom, two oxygen atoms—is a dangerous molecule. Indeed, driving down carbon-dioxide emissions has become the way that many leaders and journalists describe our task. But CH4—one carbon atom combined with four hydrogen atoms, otherwise known as methane—is carbon dioxide’s evil twin. It traps heat roughly eighty times more efficiently than carbon dioxide does, which explains why the fact that it’s spiking in the atmosphere scares scientists so much. Despite…

Fevers are plaguing the oceans — and climate change is making them worse

Fevers are plaguing the oceans — and climate change is making them worse

Nature reports: Ten years ago, dead fish began washing ashore on the beaches of Western Australia. The culprit was a huge swathe of unusually warm water that ravaged kelp forests and scores of commercially important marine creatures, from abalone to scallops to lobster. Over the following weeks, some of Western Australia’s most lucrative fisheries came close to being wiped out. To this day, some of them have not recovered. After the crisis, scientists came together to assess the damage and…

NASA reboots its role in fighting climate change

NASA reboots its role in fighting climate change

Nature reports: NASA is best known for exploring other worlds, whether that’s sending astronauts to the Moon or flying helicopters on Mars. But under US President Joe Biden, the space agency intends to boost its reputation as a major player in studying Earth — especially with an eye towards fighting climate change. “Biden made clear that climate is a priority,” says Waleed Abdalati, director of the Cooperative Institute for Research in Environmental Sciences in Boulder, Colorado. “There’s a clear role…

If we want to save the planet, the future of food is insects

If we want to save the planet, the future of food is insects

Richard Godwin writes: My first attempts at feeding insects to friends and family did not go down well. “What the hell is wrong with you?” asked my wife when I revealed that the tomato and oregano-flavoured cracker bites we had been munching with our G&Ts were made from crickets. “Hang on, I’m vegetarian!” cried our friend – which prompted a slightly testy discussion on whether insects count as meat, how many thousand arthropods equate to one mammal and considering almost…

A climate dystopia in Northern California

A climate dystopia in Northern California

Naomi Klein writes: It’s a ritual that has been repeated many times over the coldest months of Northern California’s winter. The Chico police arrive between 9 a.m. and noon on a Thursday, perhaps in the hopes of catching people when they are home. Home, in this case, being flimsy tents, draped in tarps, many of them strung up between pine trees, secured to fences, or hidden beneath highway overpasses. The cops read out orders and sometimes hand out flyers: You…

China’s greenhouse gas emissions now exceed all the developed world’s combined

China’s greenhouse gas emissions now exceed all the developed world’s combined

Bloomberg reports: China now accounts for more greenhouse gas emissions than all of the world’s developed nations combined, according to new research from Rhodium Group. China’s emissions of six heat-trapping gases, including carbon dioxide, methane and nitrous oxide, rose to 14.09 billion tons of CO2 equivalent in 2019, edging out the total of Organization for Economic Cooperation and Development members by about 30 million tons, according to the New York-based climate research group. The massive scale of China’s emissions highlights…

Brazilian Amazon released more carbon than it absorbed over past 10 years

Brazilian Amazon released more carbon than it absorbed over past 10 years

AFP reports: The Brazilian Amazon released nearly 20% more carbon dioxide into the atmosphere over the past decade than it absorbed, according to a startling report that shows humanity can no longer depend on the world’s largest tropical forest to help absorb manmade carbon pollution. From 2010 through 2019, Brazil’s Amazon basin gave off 16.6bn tonnes of CO2, while drawing down only 13.9bn tonnes, researchers reported Thursday in the journal Nature Climate Change. The study looked at the volume of…

Banks produce 700 times more greenhouse gas emissions from loans than offices

Banks produce 700 times more greenhouse gas emissions from loans than offices

Bloomberg reports: It’s through their loan books and investment portfolios that banks and asset managers make their biggest contribution to climate change. The greenhouse gas emissions associated with financial institutions’ investing, lending and underwriting activities are more than 700 times higher, on average, than their direct emissions, according to a report published Wednesday by climate nonprofit CDP. While banks generate emissions from heating their buildings and flying executives to meetings — when pandemic restrictions allow — “almost all climate-related impacts…

Halting the vast release of methane is critical for climate, UN says

Halting the vast release of methane is critical for climate, UN says

The New York Times reports: A landmark United Nations report is expected to declare that reducing emissions of methane, the main component of natural gas, will need to play a far more vital role in warding off the worst effects of climate change. The global methane assessment, compiled by an international team of scientists, reflects a growing recognition that the world needs to start reining in planet-warming emissions more rapidly, and that abating methane, a particularly potent greenhouse gas, will…

White House dances around a big contributor to climate change: Agriculture

White House dances around a big contributor to climate change: Agriculture

Politico reports: President Joe Biden needs the help of the powerful farm industry to reach his sky-high climate goals. But his plans for cutting agricultural emissions might not have enough teeth to take a big bite out of global warming. Biden on Thursday pledged a drastic reduction in U.S. greenhouse gas emissions by 2030. But the White House hasn’t set any specific targets yet for agriculture, which accounts for 10 percent of all U.S. emissions, according to the EPA. Those…

As extreme weather increases, climate misinformation makes tactical shift

As extreme weather increases, climate misinformation makes tactical shift

The Associated Press reports: Climate scientists have warned for years that a warming planet would cause more extreme storms, like the one that walloped Texas in February, knocking out power and leaving millions in a deep freeze. Yet as the snow fell and the wind howled, some looked for other explanations for the storm and its resulting power outages. The conservative website The Gateway Pundit made the false claim that President Joe Biden’s energy policies somehow prevented Texas plants from…

We are living in a climate emergency, and we’re going to say so

We are living in a climate emergency, and we’re going to say so

Mark Fischetti writes: An emergency is a serious situation that requires immediate action. When someone calls 911 because they can’t breathe, that’s an emergency. When someone stumbles on the sidewalk because their chest is pounding and their lips are turning blue, that’s an emergency. Both people require help right away. Multiply those individuals by millions of people who have similar symptoms, and it constitutes the biggest global health emergency in a century: the COVID-19 pandemic. Now consider the following scenarios:…
