Peat Fires Choking Southeast Asia Pose New Threat to Global Climate

The Indonesian peat fires that have been choking cities across Southeast Asia are creating more than a local health menace—they’re releasing immense stores of CO2.

Tracking Ice Sheets When They Were Smaller than Today

As global temperatures rise, knowing just how far Greenland’s ice sheet shrank in the past could help scientists predict sea level rise in the future.
