Researchers have confirmed that salmon are spawning in an Arctic Ocean watershed, suggesting that at least some salmon species could be expanding to new territory as climate change reshapes their habitat. The University of Alaska Fairbanks-led project found about 100 chum salmon in the Anaktuvuk and Itkillik rivers on Alaska’s North Slope. Both rivers flow […]
The leader of the nation’s top scientific research organization will visit Utqiaġvik, Alaska, to highlight important research taking place at the northernmost city in the country, in a region of the world that is warming three to four times as fast as the global average. Dr. Asmeret Asefaw Berhe is the first Earth scientist to […]
Most of Earth’s near-surface permafrost could be gone by 2100, an international team of scientists has concluded after comparing current climate trends to the planet’s climate 3 million years ago. The team found that the amount of near-surface permafrost could drop by 93% compared to the preindustrial period of 1850 to 1900. That’s under the […]
The climate-driven advance of beavers into the Arctic tundra is causing the release of more methane — a greenhouse gas — into the atmosphere. Beavers, as everyone knows, like to make dams. Those dams cause flooding, which inundates vegetation and turns Arctic streams and creeks into a series of ponds. Those beaver ponds and surrounding […]
