Cold War-era Alaskan tunnel yields clues on climate
2016-03-30 15:08:08| Climate Ark Climate Change & Global Warming Newsfeed
ClimateWire: Ten miles north of Fairbanks, along a man-made valley cleared by industrial gold dredgers in the early 1900s, a small red building at the base of a hill provides a portal to the geologic history of central Alaska. Behind a locked metal door lies the Cold Regions Research and Engineering Laboratory, a 360-foot tunnel that gives scientists hands-on, underground access to frozen permafrost dating from the present to nearly 50,000 years in the past. Operated by the Army Corps of Engineers and the...

A newly discovered Alaskan butterfly may hold clues to climate change
2016-03-26 23:37:00| Climate Ark Climate Change & Global Warming Newsfeed
Boston Globe: Researchers discovered a possible new butterfly species in Alaska and believe it could tell us more about the pace of climate change. The Tanana Arctic, or Oeneis tanana, probably evolved from a rare hybrid when two butterfly species mated before the last ice age, according to a study published this month in the Journal of Research on the Lepidoptera. While the butterfly could help shed light on the North American Arctic's geological history, it can also serve as a sort of canary in the coal...

New Alaskan butterfly: monitor for climate change?
2016-03-19 21:42:00| Climate Ark Climate Change & Global Warming Newsfeed
Christian Science Monitor: A butterfly species, misidentified for more than 60 years, may be the only type of butterfly endemic to Alaska, say scientists. The newly identified Tanana Arctic lives in spruce and aspen forests in the Tanana-Yukon River Basin. Because butterflies react quickly to climate change, the species could help scientists identify alarming changes in the sensitive arctic ecosystem, says Andrew Warren, a lepidopterist (butterfly expert) at the University of Florida in Gainesville. This butterfly has...

Alaskan Yellow Cedar: Saving It, A New Report
2016-01-25 20:03:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World News: As less and less snow has fallen over the West Coast, yellow-cedar forests across Alaska have rapidly declined within the last century. The stately conifers grow up to 78 feet tall and are historically a major part of forests north of the top of California. A new report from the U.S. Forest Service's Pacific Northwest Research Station addresses the threat to them and outlines a climate adaptation strategy designed to help save the iconic trees. "Our report assesses the past, current, and expected...
