Climate change causing US wildfire season to last longer, Congress told

Guardian: America's wildfire season lasts two months longer than it did 40 years ago and burns up twice as much land as it did in those earlier days because of the hotter, drier conditions produced by climate change, the country's forest service chief told Congress on Tuesday. But the forest service was forced to make sharp cuts to fire prevention programmes, and reduce the numbers of fire-fighters and engines because of budget pressures, Thomas Tidwell, the chief of the United States Forest Service, told...

Drought, climate change and forest practices elevate Utah wildfire risk

Salt Lake Tribune: So is the hazard created by modern forest management, said Michael Jenkins, associate professor in USUs Quinney College of Natural Resources. Aggressive management has been "essentially eliminated," and dry forest undergrowth has built up, turning parts of Utah into tinderboxes, he said. "Forests today are in a much different state than they were 200 years ago when fires were more common," Jenkins said. "We have suppressed fires for 100 years, which has allowed fuels to build up, trees to get...

Climate change may increase the risk of severe thunderstorms
2013-06-04 17:15:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: Analysis has suggested that changes in the atmosphere will lead to more frequent conditions favorable for severe thunderstorms. According to recent studies there will be more damaging winds related to thunderstorms. The number of tornadoes and large hail is expected to remain at the same level as today. Climate model simulations suggest that on average, as the surface temperature and moisture increases the conditions for thunderstorms becomes more frequent. Climate change decreases temperature...

Climate change threatens 82% of native California fish
2013-06-01 16:01:00| Climate Ark Climate Change & Global Warming Newsfeed
USA Today: Four of five native fish in California, including salmon and steelhead trout, likely will be driven to or near extinction within 100 years if climate change continues on its current path, a new study predicts. Of 121 native fish species, 82% will plummet in number or disappear because they need cool, flowing water yet climate change is boosting temperatures and lessening stream flow, according to scientists at the University of California-Davis' Center for Watershed Science. In contrast, only 19%...

Study: Climate change a death knell for most Californian fish
2013-06-01 00:49:00| Climate Ark Climate Change & Global Warming Newsfeed
Grist: Cold-water-loving fish will find California`s rivers and streams to be increasingly inhospitable - and deadly. A study published in the online journal PLOS ONE finds that rising water temperatures may drive many of the state`s native species extinct, while helping invasive fish flourish. From the study: Most native fishes will suffer population declines and become more restricted in their distributions; some will likely be driven to extinction. Fishes requiring cold water [less than 72 degrees]...
