Fires in the Amazon forest may melt sea ice in Antarctica
Satellite data reveal a link between the amount of black carbon in the atmosphere and rates of Antarctic sea ice loss in recent years.

Buying carbon credits to fight climate change? Here’s what to know
Carbon credits sold on the voluntary market are under scrutiny for not offsetting greenhouse gas emissions as claimed.
- Paleontology
Sloths once came in a dizzying array of sizes. Here’s why
A new fossil and DNA analysis traces how dozens of sloth species responded to climate shifts and humans. Just two small tree-dwelling sloths remain today.

An idea to save Mexico’s oyamel forests could help monarch butterflies too
Climate change is putting monarch butterflies’ overwintering forests in Mexico at risk. Could planting new forests solve that problem?

Unearthed ice may be the Arctic’s oldest buried glacier remnant
Thanks to climate change, thawing permafrost in the Canadian Arctic has revealed the buried remnant of a glacier that’s 770,000 years old.

Seafloor amber may hold hints of a tsunami 115 million years ago
Oddly shaped deposits of tree resin point to massive waves that struck northern Japan roughly 115 million years ago and swept a forest into the sea.
