Coping With Climate Stress in Antarctica

Wed, 17 Jan 2018 14:42:00 EST

Some Antarctic fish living in the planet’s coldest waters are able to cope with the stress of rising carbon dioxide levels in the ocean. They can even tolerate slightly warmer waters. But they can’t deal with both stressors at the same time, according to a study from the University of California, Davis.(image)



NASA IMERG Reveals Rainfall Rates of Tropical Cyclone Berguitta

Wed, 17 Jan 2018 15:27:00 EST

Heavy rain surrounded Tropical Cyclone Berguitta as it continued to move toward the island of Mauritius in the Southern Indian Ocean. NASA calculated the rate in which rain was falling within the hurricane-strength storm in the Southern Indian Ocean.(image)



Weather anomalies accelerate the melting of sea ice

Tue, 16 Jan 2018 10:16:00 EST

ETH researchers reveal why Arctic sea ice began to melt in the middle of winter two years ago – and that the increased melting of ice in summer is linked to recurring periods of fair weather.(image)



Warming Signs: How Diminished Snow Cover Puts Species in Peril

Tue, 16 Jan 2018 09:18:00 EST

The wolverine is highly adapted to life in a snowy world. It has thick fur and snowshoe-like feet, and it dens high in the mountains as a way to avoid predators that aren’t as nimble in deep snow and to provide its kits with insulation from the bitter high-elevation cold.(image)



Jet Stream Changes Since 1960s Linked to More Extreme Weather

Mon, 15 Jan 2018 10:26:00 EST

Increased fluctuations in the path of the North Atlantic jet stream since the 1960s coincide with more extreme weather events in Europe such as heat waves, droughts, wildfires and flooding, reports a University of Arizona-led team.The research is the first reconstruction of historical changes in the North Atlantic jet stream prior to the 20th century. By studying tree rings from trees in the British Isles and the northeastern Mediterranean, the team teased out those regions' late-summer weather going back almost 300 years — to 1725.(image)



Lanternfish reveal how ocean warming impacts the twilight zone
