Rapid changes in the environment brought on by warming temperatures and increasing ocean acidification are prompting new direction in research, say scientists who addressed the 2020 Alaska Marine Science Symposium in Anchorage, Alaska. “Everything is new,” said Cisco Werner, chief science advisor to NOAA Fisheries, in his presentation to dozens of participants gathered to […]
The common murre is a self-sufficient, resilient bird. Though the seabird must eat about half of its body weight in prey each day, common murres are experts at catching the small “forage fish” they need to survive. Herring, sardines, anchovies and even juvenile salmon are no match for a hungry murre. So when nearly […]
University of Alaska Fairbanks scientists presented their work at the American Geophysical Union’s fall meeting in San Francisco this week. Here are some research highlights from the world’s largest Earth and space science meeting. A decades-old research project on Alaska’s North Slope indicates that deciduous shrubs shift more carbon from the soil to the atmosphere […]
“If this were an annual health check-up, I think we’d have to say that the Arctic is chronically sick and getting worse.” In addition to warning that “the feedback to accelerating climate change may already be underway,” the U.S. government’s latest report on conditions in the Arctic reveals that temperatures in the region are persistently warming, […]
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 […]
Video: Guðfinna Aðalgeirsdóttir, also known as Tolly, a glaciologist and university professor from Iceland, recommends people watch Swedish high-school student Greta Thunberg’s presentation. Youtube Icelanders will soon install a plaque they hope people will read, long after those who bolted it to a mountain are dead. Near a withering glacier, the sign reads: […]
Earth’s global surface temperatures in 2018 were the fourth warmest since 1880, according to independent analyses by NASA and the National Oceanic and Atmospheric Administration (NOAA). Global temperatures in 2018 were 1.5 degrees Fahrenheit (0.83 degrees Celsius) warmer than the 1951 to 1980 mean, according to scientists at NASA’s Goddard Institute for Space Studies […]
Current international climate policies do not take into account full effects on global climate The weather these days is wild and will be wilder still within a century. In part, because the water from melting ice sheets off Greenland and in the Antarctic will cause extreme weather and unpredictable temperatures around the globe. A study […]
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 […]
