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.

Trees ‘remember’ times of water abundance and scarcity
Spruce trees that experienced long-term droughts were more resistant to future ones, while pines acclimatized to wet periods were more vulnerable.

Some trees are coping with extreme heat surprisingly well
Rising temperatures could reduce trees' ability to photosynthesize. Scientists are trying to figure out just how close we are to that point.

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.
