Arctics Boreal Forests Burning At Unprecedented Rate
2013-07-22 23:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Climate Central: In a sign of how swiftly and extensively climate change is reshaping the Arctic environment, a new study has found that the region's mighty boreal forests -- stands of mighty spruce, fir, and larch trees that serve as the gateway to the Arctic Circle -- have been burning at an unprecedented rate during the past few decades. The study, published Monday in the Proceedings of the National Academy of Sciences, found that the boreal forests have not burned at today's high rates for at least the past 10,000...

Canada needs to up conservation game, preserving half of boreal forests: paper
2013-07-22 04:09:00| Climate Ark Climate Change & Global Warming Newsfeed
Windsor Star: A group of top international scientists says Canada needs to dramatically up its conservation game to ensure its vast northern forests remain healthy in the face of increasing industrial pressure. In a paper to be presented today at the International Congress of Conservation Biology in Baltimore, Md., its authors argue that Canada needs to preserve about half of its boreal forest. That's significantly more than the 10 per cent level researchers previously thought was necessary to conserve natural...
In the Greenhouse: Forests Get More Water Efficient as Carbon Dioxide Levels Rise
2013-07-11 04:46:00| Climate Ark Climate Change & Global Warming Newsfeed
Time: The response to climate change has two sides: mitigation and adaptation. Mitigation means reducing greenhouse gases in an effort to slow the pace of warming and lessen its effects. Adaptation means responding to those effects, working to blunt climate change as it unfolds. It`s offense versus defense. Mitigation gets most of the attention because it mostly involves changing the way we use energy, something that we spend trillions of dollars on. Such shifts can have a huge impact on the economy--for...

Tropical Forests Sensitive to Global Warming: A Study
2013-07-08 22:31:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World News: Tropical forests are intensely sensitive to climate change, causing them to produce more flowers in response to only slight increases in temperature, according to a new study conducted by the University of California, Santa Barbara's National Center for Ecological Analysis and Synthesis (NCEAS). Published in the journal Nature Climate Change, the study, which used a new globally gridded satellite dataset, examined how changes in temperature, clouds and rainfall affect the number of flowers tropical...

The Southwests forests may never recover from megafires

Grist: If you doubt that climate change is transforming the American landscape, go to Santa Fe, N.M. Sweltering temperatures there have broken records this summer, and a seemingly permanent orange haze of smoke hangs in the air from multiple wildfires. Take a ride into the mountains and you`ll see one blackened ridge after another where burns in the past few years have ravaged the national forest. Again, this year, fires in New Mexico and neighboring states of Colorado and Arizona are destroying wilderness...
