Atmospheric concentrations of CO2 are set to pass 400 ppm, far faster than scientists would have predicted. That shows how difficult it’s been to reduce carbon emissions—and points the way towards dangerous warming in the future
Last year was the hottest ever for the continental U.S. — and it wasn’t even close. Just in case you needed more evidence that the climate really is changing
A new study shows that temperatures in West Antarctica—which has enough ice to raise sea levels by 10 ft.—are rising nearly twice as fast as scientists had believed.
When people have personal experience with climate change, they tend to become believers—unless they were already skeptics. Will extreme weather events like Sandy be enough to change the equation on climate change belief?
The rate of polar ice-sheet melting is key to calculating how fast sea levels are rising. Now, scientists have a new analysis of polar ice loss in Greenland and Antarctica—and the numbers aren’t good for the planet.
A familiar modern problem may have wiped out a grand ancient culture
I’ve been fortunate enough to travel around the world as TIME’s environment correspondent: to rainforests, Himalayan mountains, coral reefs. But far and away the most singular spot I ever visited was the far north of Greenland. I …
When you mess with the Amazon rainforest you mess with a lot of things — 2.5 million species of insects, 40,000 species of plants, 1,300 species of birds, and those are only the known ones. The 1.4 billion of acres of thriving, …
