Alaskan Forest Fires Could Make Climate Change Much Worse

2015-10-20 22:41:00| Climate Ark Climate Change & Global Warming Newsfeed

Gizmodo: If humans want to limit global warming, well need to drastically reduce our carbon pollution. We might need to do so even faster than our models suggest, because as scientists are now discovering, theres an additional factor working against us: fire. Last week, we learned that Indonesia is in the midst of a devastating fire season, one thats sending as much carbon skyward as the entire US economy. Indonesia isnt alone -- Western North America is currently recovering from one of the most brutal...

Alaskan boreal forest fires release more carbon than trees can absorb

2015-10-19 21:02:00| Climate Ark Climate Change & Global Warming Newsfeed

ScienceDaily: A new analysis of fire activity in Alaska's Yukon Flats finds that so many forest fires are occurring there that the area has become a net exporter of carbon to the atmosphere. This is worrisome, the researchers say, because arctic and subarctic boreal forests like those of the Yukon Flats contain roughly one-third of Earth's terrestrial carbon stores. The research is reported in the journal Nature Climate Change. Alaska fire records go back only to 1939, and scientists often assume that present-day...

Alaskan Wind Power Capacity Increased 20 Fold since 2007, Report Says

Yale Environment 360: Alaskas wind power capacity increased 20 fold between 2007 and 2014, from 3 megawatts to 60 megawatts, according to an analysis by the U.S. Energy Information Administration. The state, which is known for its vast oil reserves, increased wind power capacity with a blend of utility-scale and distributed, or small-scale, projects. The marked increase is especially notable because Alaska's immense area and sparse population make expanding the grid and adapting it to renewables costly, and the rugged...

Alaskan Greens: Obamas Words, Actions Conflict On Climate Change

2015-08-31 01:29:00| Climate Ark Climate Change & Global Warming Newsfeed

KUCB: President Barack Obama's visit to Alaska this week, aimed at highlighting his push to fight climate change, comes just two weeks after his administration approved drilling for oil in the Arctic Ocean. Some Alaskan environmentalists see a disconnect between the president's rhetoric and his actions on climate change. The Obama administration hopes the Alaska trip--Obama arrives in Anchorage Monday afternoon--will help sell the president's proposals to rein in America's greenhouse gas emissions....
