Arctic sea ice could disappear completely through September each summer if average global temperatures increase by as little as 2 degrees, according to a new study by the University of Cincinnati. The study by an international team of researchers was published in Nature Communications. “The target is the sensitivity of sea ice to temperature,” said Won […]
Climate Crisis Sends Stream Temperatures Off the Charts HOMER, AK— As Alaskans suffer through the smoke, haze and danger of a record-breaking heat wave, Alaska’s salmon are suffering too. On July 7th, stream temperatures topped 81.7 oF (27.6 oC) in the Deshka River, a major salmon stream on the west side of Cook Inlet […]
A new paper shows that air temperature is the “smoking gun” behind climate change in the Arctic, according to John Walsh, chief scientist for the University of Alaska Fairbanks International Arctic Research Center. Several UAF researchers are co-authors on the paper, which says that “increasing air temperatures and precipitation are drivers of major changes […]
New NASA research has found that increases in the rate at which Arctic sea ice grows in the winter may have partially slowed down the decline of the Arctic sea ice cover. As temperatures in the Arctic have warmed at double the pace of the rest of the planet, the expanse of frozen seawater that […]
[dropcap]P[/dropcap]alo Alto, CA– New research, led by former Carnegie postdoctoral fellow Summer Praetorius, shows that changes in the heat flow of the northern Pacific Ocean may have a larger effect on the Arctic climate than previously thought. The findings are published in the August 7, 2018, issue of Nature Communications. The Arctic is experiencing larger […]
When the Chicxulub asteroid smashed into Earth 65 million years ago, the event drove an abrupt and long-lasting era of global warming, a new study reports. The results , published in the May 25 issue of Science, suggest that the asteroid impact caused a rapid temperature increase of 5 degrees Celsius (roughly 9 degrees Fahrenheit) that endured for […]
Researchers are curious to see if they will come across a “cold pool” during this year’s annual Southeastern Bering Sea Shelf Bottom Trawl Survey given the unusually warm winter and the limited sea ice coverage in 2017/2018. They suspect they might not, and that would be a first. The “cold pool” is a large mass […]
Two things happened on top of the world this week. In Utqiagvik (formerly Barrow), on Jan. 22 the sun topped the horizon for the first time since mid-November. The day before that, Jan. 21, was the first time since Halloween the town’s thermometers recorded a below-normal daily average air temperature. The returning daylight for the […]
The Arctic is warming twice as fast as anywhere else on Earth, which is already affecting the nearly 4 million people living in the region, the fish and wildlife they depend on for food, and their environment. The changes have ramifications far beyond the Arctic to global economies, weather, climate, sea levels, trade and national […]
