The global study examined hourly records of temperature, cloud cover, specific humidity, and precipitation. (One of the Expedition 40 crew members aboard the International Space Station photographed this nighttime image showing city lights in at least half a dozen southern states from some 225 miles above the home planet.

Oxygen levels in the ancient oceans were surprisingly resilient to climate change, new research suggests. Scientists used geological samples to estimate ocean oxygen during a period of global warming 56 million years ago — and found “limited expansion” of seafloor anoxia (absence of oxygen). Global warming — both past and […]
