Global warming: Forest timberline impacts not so clear

Summit Voice: For residents of high-elevation regions, including Colorado -- the impacts of global warming include a potentially radical change in the composition of plant communities. In mountainous areas, the distribution of many species is limited by factors related to elevation, including temperature. With warmer and drier conditions potentially limiting growth at lower elevations, scientists have already documented the treeline creeping upward in some areas, but there are additional factors to consider,...

Global warming not significant in 2012 drought: Feds
2013-04-12 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Climate Central: The extreme 2012 Central Great Plains drought was more intense than the Dust Bowl era droughts of the 1930s, according to a new federal assessment of the origins and predictability of the drought, released on Thursday. The team of 19 atmospheric scientists, led by the National Oceanic and Atmospheric Administration (NOAA), found that global warming may have played a relatively small contributing role by helping to make the drought slightly warmer, and hence drier, than it otherwise might have been....

Global warming not a big factor in 2012 drought
2013-04-12 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Summit County Voice: Last summer`s crippling Great Plains drought can`t definitively be linked with global warming, according to a team of federal scientists from various agencies. In a new report issued this week, the researchers said the drought was probably caused by a confluence of natural climate variations that might only come together in a similar constellation once a century. Cyclical variations in ocean temperatures -- especially the combination of a cooler-than-average Pacific Ocean and a warm phase of the...

USDA Climate Head: Global Warming To Bring More 'Miserable Days'
2013-04-12 10:00:00| Climate Ark Climate Change & Global Warming Newsfeed
U.S. News and World Report: The director of the United States Department of Agriculture's Climate Change Program said Wednesday that global warming will cause an increase in the number of "miserable days" over the next several years. William Hohenstein said that the "misery index," a measure of temperature and humidity, will continue to get higher in many parts of the country, especially the southwest. He said the number of days with temperatures above100 degrees will increase. With it, farmers might face increasingly difficult...
Global warming: time to rein back on doom and gloom?
2013-04-05 21:26:00| Climate Ark Climate Change & Global Warming Newsfeed
Telegraph: All right, I accept that this Arctic April may seem an incongruous time to address global warming. But there are important, and possibly hopeful, developments in the complex, contentious world of climate science that might finally give us all a sense of spring. For some recent research suggests that climate change might not be as catastrophic as the gloomiest predictions suggest. The research, moreover, comes at a time when many experts are beginning to despair that warming can be prevented from...
