Northern forests rev up carbon cycle
2013-08-09 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature: Northern forests are not just surviving but thriving, despite concerns about droughts, wildfires and bark beetles surging as the world warms. Ecosystem productivity is rising at high latitudes, with a roughly 50% increase in the amount of carbon cycling through northern landscapes since the 1950s, according to an analysis of atmospheric carbon dioxide trends published today in Science1. Boreal forests in particular have shown marked increases in carbon uptake during summer. Something quite massive...

Are we losing primary forests in the Congo Basin?
2013-08-08 07:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Environ Research: The researchers assessed primary-forest changes at the national scale and modelled potential changes assuming that population growth, logging activity and maintenance infrastructure will remain the same. The analysis was based on mid-resolution satellite imagery and results of forest cover/change detection assessment of intact forest landscapes an approach that allowed the team to analyse intact and non-intact or degraded primary forests separately. The results show that almost 1% of primary forests...

The Rise of Rubber Takes Toll On Forests of Southwest China
2013-08-01 15:01:00| Climate Ark Climate Change & Global Warming Newsfeed
Yale Environment 360: In the 1960s, when Zhou Fabei moved to Xishuangbanna prefecture, a tropical corner of southwest Chinas Yunnan province, he quickly landed a job building roads for new rubber plantations. The timing of his move from the populous central province of Hunan couldnt have been better for him: Chinas post-revolutionary government had just started slashing forests and promoting rubber cultivation by state-run firms. By the 1980s, the government was offering incentives to the prefectures poor farmers...
The role of Chinas forests in mitigating climate change
2013-07-27 11:57:00| Climate Ark Climate Change & Global Warming Newsfeed
World Agro Forestry: Forest areas in China are rapidly expanding through reforestation and afforestation activities. There has been much discussion in China about opportunities for climate change mitigation through carbon sequestration and through opportunities for producing feedstock for electricity generation and liquid fuels from new forest plantations. There has been less discussion about the role that existing forests could and should play in climate change mitigation. A recent set of studies carried out by an...

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...
