Due to warming climate and increasing human exploitation, far northern forests and the tundra beyond are undergoing rapid changes. In northern Alaska, scientists from Columbia University’s Lamont-Doherty Earth Observatory and other institutions are studying the responses of trees at the very edge of their range.
As the American Southwest grows hotter, the risk of severe, long-lasting megadroughts rises, passing 90 percent this century if greenhouse gas emissions continue at their current pace, a new study from scientists at Lamont-Doherty Earth Observatory says. Aggressively reducing emissions can cut that risk.
The sound of a chainsaw rises discordantly above all natural sounds, disrupting the quiet of a warm African winters’ day, a destructive sound at odds with the African wilderness. But it is not a tree that is being felled. It is the horn of a rhino.
