Permafrost thaw beneath Arctic lakes poses surprise pollution threat

Permafrost thaw beneath Arctic lakes poses surprise pollution threatThermokarst lakes, formed from thawing permafrost, in Alaska

As the Arctic gets warmer, large quantities of greenhouse gas could be released from the sediment at the bottom of lakes, a source that has previously been overlooked.

The frozen soil of the Arctic has already started to thaw, triggering the release of more methane and carbon dioxide into the atmosphere. This climate feedback is well known, but most modelling only accounts for thawing in the top 3 metres of Arctic soil.

The Tipping Points of Climate Change — and Where We Stand

We’re nearly halfway through the 2020s, dubbed the most decisive decade for action on climate change. Where exactly do things stand? Climate impact scholar Johan Rockström offers the most up-to-date scientific assessment of the state of the planet and explains what must be done to preserve Earth’s resilience to human pressure.

Reporting on Doomsday Scenarios | 60 Minutes Full Episodes

From 2022, Jon Wertheim’s report on “preppers” who are gearing up for extreme catastrophes. From 2008, Scott Pelley’s visit to the “doomsday vault” inside a mountain near the North Pole, built to warehouse backup copies of all the world’s crops. From 2023, Pelley’s interviews with scientists who say the planet is in the midst of a sixth mass extinction with Earth’s wildlife running out of places to live. And also from 2023, Bill Whitaker’s story on virus hunters who are searching for new pathogens to help prevent another pandemic.

Buried deep in an Australian cave, archaeologists have uncovered evidence that an Aboriginal ritual may have been passed down 500 generations and survived 12,000 years, making it the oldest known continuous cultural practice in the world, according to a new study.

‘What if there just is no solution?’ How we are all in denial about the climate crisis

In his new book, Tad DeLay suggests there is no rosy roadmap to go forward – but there are things we can do

You are in denial about the climate crisis. We all are, argues the American scholar Tad DeLay. Right-wing climate deniers are not the only ones with a problem, he says when we speak in early June after the release of his book, Future of Denial. For denial doesn’t only amount to rejecting the evidence, he argues – it also consists of denying our role in the climate crisis; absolving ourselves through “carbon offsets, hybrid cars, local purchases, recycling”. And in this, far more of us are implicated.

Sometimes it is almost impossible not to feel hopeless and broken,” says the climate scientist Ruth Cerezo-Mota. “After all the flooding, fires, and droughts of the last three years worldwide, all related to climate change, and after the fury of Hurricane Otis in Mexico, my country, I really thought governments were ready to listen to the science, to act in the people’s best interest.”

‘We were in disbelief’: Antarctica is behaving in a way we’ve never seen before. Can it recover?

Antarctic sea ice has been disappearing over the last several summers. Now, climate scientists are wondering whether it will ever come back.
