Land Disturbances Darken Snow and Increase Melt Rate, Researchers Say
2015-01-08 20:02:00| Climate Ark Climate Change & Global Warming Newsfeed
Yale Environment 360: Land disturbances, such as agricultural practices and development, may have a big impact on snow purity and melt rates, according to a large-scale survey of impurities in North American snow by researchers at the University of Washington. During a nearly 10,000-mile trek across North American snowfields, the researchers were particularly interested in the Bakken oil fields of northwest North Dakota. Before undertaking the study, they predicted that diesel emissions and air pollution associated with...
NRL Researchers Study Solar Disturbances And Their Impact On Satellite Navigation Systems

Climate change is fueling forest disturbances, study shows
2014-08-05 03:06:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: Climate change is already altering the environment. Long-lived ecosystems such as forests are particularly vulnerable to the comparatively rapid changes in the climate system. A new international study published this week in Nature Climate Change shows that damage from wind, bark beetles, and wildfires has increased drastically in Europe's forests in recent years. "Disturbances like windthrow and forest fires are part of the natural dynamics of forest ecosystems, and are not, therefore, a catastrophe...

Climate 'key driver' in European forest disturbances
2014-08-05 01:58:00| Climate Ark Climate Change & Global Warming Newsfeed
BBC: Europe's forests have experienced increased disturbances throughout the 20th Century from wind, bark beetles and wildfires, a study has shown. A team of European-based scientists identified climatic changes as a "key driver behind this increase". However, they added, how the expected continuation of climate change would affect Europe's forests in the future remained unresolved. The findings have been published online by the journal Nature Climate Change. The researchers wrote: "Natural...
