Why is the boreal forest breathing CO2 more deeply?
2013-08-09 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Scientific American: The boreal forest seems to like the higher levels of carbon dioxide that result from fossil-fuel burning. All that carbon appears to be enabling growth rates not seen in human history for the northernmost forest, according to a new study. "Boreal forests are more active than 50 years ago," says geochemist Heather Graven of the Scripps Institution of Oceanography, lead author of the new analysis, published online August 8 in Science. She and her colleagues documented a dramatic uptick in the flow...

Global Warming Linked with Frequent Fires in Alaska's Boreal Forests
2013-07-23 15:02:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World News: A new study from the University of Illinois has shown that Yukon Flats of interior Alaska, one of the most flammable regions of the world, is seeing more frequent and severe fires now than it had in the past 10,000 years. Researchers attribute this increase to global warming. Recently, large wildfires in Alaska have charred more than half a million acres at a time, The Los Angeles Times reported. Another recent study had found that wildfires may drive up global warming by releasing more carbon-containing...

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...
