In a recent paper, scientists wrote that a small population of polar bears living off Greenland and Arctic Canada increased by 1.6 times when they compared the numbers from the 1990s to 2013 and 2014. They concluded that lighter sea ice might have benefitted the animals. That’s because sunshine penetrates thinner ice better, which stimulates […]
JUNEAU, Alaska — The size of Alaska’s population remained essentially unchanged from July 2021 to July 2022, based on population estimates released today by the Alaska Department of Labor and Workforce Development. The state grew by an estimated 451 people — 0.06 percent — the second consecutive year of small increase. Despite slight overall growth, […]
The regrowth of Amazonian forests following deforestation can happen much slower than previously thought, a new study shows. The findings could have significant impacts for climate change predictions as the ability of secondary forests to soak up carbon from the atmosphere may have been over-estimated. The study, which monitored forest regrowth over two decades, […]
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 […]
