An ocean current called the Atlantic Meridional Overturning Circulation will weaken by 50 percent by 2100. The question is what to do about it.

Soil DNA from Chile to the Antarctic Peninsula ties warmer climates to more plant fungal pathogens, with abundance projected to double by 2100.

An AI trained to use thermal images to detect whale body heat could help warn ships at risk of colliding with the marine mammals.

A new study links the sun's 11-year cycle to accelerated orbital loss, with debris falling faster once sunspot numbers near their cycle peak.
