Humans settled, set fire to Madagascar's forests 1,000 years ago

PhysOrg: Scientists from MIT and the University of Massachusetts at Amherst have found that a widespread and permanent loss of forests in Madagascar that occurred 1,000 years ago was due not to climate change or any natural disaster, but to human settlers who set fire to the forests to make way for grazing cattle. The researchers came to this conclusion after determining the composition of two stalagmites from a cave in northwestern Madagascar. Stalagmites form from water that percolates from the surface,...
Europes Shift to Dark Green Forests Fuels Warming
2016-02-07 16:01:00| Climate Ark Climate Change & Global Warming Newsfeed
Reuters: An expansion of Europe's forests towards dark green conifers has stoked global warming, according to a study at odds with a widespread view that planting more trees helps human efforts to slow rising temperatures. Forest changes have nudged Europe's summer temperatures up by 0.12°C (0.2°F) since 1750, largely because many nations have planted conifers such as pines and spruce whose dark colour traps the sun's heat, the scientists said. Lighter-colored broad-leafed trees, such as oak or birch,...

Cause for hope: Secondary tropical forests put on weight fast
2016-02-05 22:02:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: How fast tropical forests recover after deforestation has major consequences for climate change mitigation. A team including Smithsonian scientists discovered that some secondary tropical forests recover biomass quickly: half of the forests in the study attained 90 percent of old-growth forest levels in 66 years or less. Conservation planners can use their resulting biomass-recovery map for Latin America to prioritize conservation efforts. "Regenerating secondary forests could play a critical...
Recovering tropical forests a sponge for CO2: study
2016-02-05 05:43:00| Climate Ark Climate Change & Global Warming Newsfeed
Agence France-Presse: Tropical forests reclaiming land cleared for agriculture or livestock not only grow quickly, but absorb far more CO2 from the atmosphere than old-growth trees, according to a study released. The research, published in the journal Nature, challenges long-standing assumptions that virgin tropical forests untouched by logging or industry do a better job of sopping up carbon dioxide and, in so doing, slowing the pace of global warming. It is also good news because it means regenerating tropic forests...
