Cleveland Volcano, Aleutian Islands eruption in 2006. Volcanism is one of the main carbon dioxide sources in the long-term carbon cycle balanced by weathering sinks, which, among others, represent important processes included in Komar and Zeebe’s model.

Among the report’s case studies: Africa’s Kariba Dam, the world’s largest man-made reservoir, impounding 181 km³ of water. Almost $300 million was loaned in 2014 to repair the dam, with completion expected by 2023. The report says “Dams like Kariba will likely continue to operate much longer with recurring investments […]

Bhattacharya How to Identify Heat-Stressed Corals Researchers have found a novel way to identify heat-stressed corals, which could help scientists pinpoint the coral species that need protection […]

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. Lights […]

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 […]

Fishing boats amidst “Arctic sea smoke” near Qingdao, China on January 7th. Arctic sea smoke is a result of frigid air passing over relatively warm water; the phenomenon is rare, even in the Arctic.

Mollusks of a sample from Southern Israel: in red, those belonging to species of Red Sea origin, in blue, those of Mediterranean origin. Native species are very few, whereas tropical ones are dominant, marking the transformation of the ecosystem. Credit: © Paolo Albano Most native species are going locally extinct, […]

ANIMATION While there are efforts to reinforce its beaches and marshes, some of Barataria Bay is slowly slipping away Sandwiched between the Mississippi River and Bayou Lafourche, the Barataria Bay in Louisiana is a latticework of shrinking marsh, swamp, and islands. Few other coastlines in the Mississippi River Delta—or anywhere […]
