3 Antarctic glaciers show rapidly accelerated ice loss from ocean warming
SAN FRANCISCO — Several Antarctic glaciers are undergoing dramatic acceleration and ice loss. Hektoria Glacier, the worst affected, has quadrupled its sliding speed and lost 25 kilometers of ice off its front in just 16 months, scientists say. The rapid retreat “is really unheard of,” says Mathieu Morlighem, a glaciologist at Dartmouth College who was…
Paris climate goal of less than 2°C of warming is within our grasp
WHEN the 2015 Paris Agreement anchored the goal to keep global warming “well below 2°C“, most people I spoke with at the time thought it was dead on arrival. I was at the COP21 summit in France and, despite the can-do spirit, many people felt achieving this was effectively impossible. Conventional wisdom says we are…
How will we actually know when we pass 1.5°C of warming?
It looks likely that the world will pass 1.5°C of warming in the 2030s, but current climate definitions would only make this failure official 10 years later, which could waste time in bringing temperatures back down Source link
World predicted to break 1.5°C warming limit for first time in 2024
A fire in Tenterfield, New South Wales, Australia, on 1 November – a potential result of extreme weather brought about by climate change Australian Associated Press/Alamy Next year could be the first where the average global surface temperature is more than 1.5°C warmer than the pre-industrial era, according to a forecast by the UK’s Met…
Ancient climate analysis suggests CO2 causes more warming than thought
Illustration of Earth 65 million years ago, when CO2 levels were much higher than those of today CHRIS BUTLER/SCIENCE PHOTO LIBRARY It is possibly the toughest question in climate science: how much warming does carbon dioxide cause? A new analysis of 66 million years of Earth’s climate history suggests the planet is much more sensitive…
