Darker Arctic boosting global warming
2014-02-17 22:52:00| Climate Ark Climate Change & Global Warming Newsfeed
Associated Press: The Arctic isn't nearly as bright and white as it used to be because of more ice melting in the ocean, and that's turning out to be a global problem, a new study says. With more dark, open water in the summer, less of the sun's heat is reflected back into space. So the entire Earth is absorbing more heat than expected, according to a study published Monday in the Proceedings of the National Academy of Sciences. Melting Arctic ice called economic time bomb That extra absorbed energy is so...

Global Warming Pushes Native Plants to New Habitats Leaving Dependent Species at Risk
2014-02-17 21:33:00| Climate Ark Climate Change & Global Warming Newsfeed
Climate News: By 2100, vegetation patterns will be shifting in almost half the land area of the planet, according to new research in the journal Global and Planetary Change. Song Feng of the University of Arkansas in the U.S. and colleagues in Nebraska, China and South Korea have taken a long cool look at what the projected patterns of warming are likely to do to the planets mosaic of climate types. And they predict dramatic changes. Climate type is a century-old idea useful for making sense of geographical...

Warming from Arctic Sea Ice Melting More Dramatic than Thought
2014-02-17 21:25:00| Climate Ark Climate Change & Global Warming Newsfeed
LiveScience: Melting Arctic sea ice has contributed considerably more to warming at the top of the world than previously predicted by climate models, according to a new analysis of 30 years of satellite observations. Sea ice helps cool the Arctic by reflecting incoming solar radiation back into space. Because of its light color, sea ice has what is known as high albedo, which is the percentage of solar radiation a surface reflects back to space. Dark ocean water left behind by melting sea ice, on the other...
Global warming: Warning against abrupt stop geoengineering method

ScienceDaily: As a range of climate change mitigation scenarios are discussed, University of Washington researchers have found that the injection of sulfate particles into the atmosphere to reflect sunlight and curb the effects of global warming could pose a severe threat if not maintained indefinitely and supported by strict reductions in greenhouse gas (GHG) emissions. The new study, published today, 18 February, in IOP Publishing's journal Environmental Research Letters, has highlighted the risks of large...

Bill Nye Scolds GOP Congresswoman On Global Warming
2014-02-16 21:48:00| Climate Ark Climate Change & Global Warming Newsfeed
Time: Bill Nye "The Science Guy" told Rep. Marsha Blackburn (R-Tenn.) to stop questioning the facts behind climate change Sunday morning, as the congresswoman said the "engineer and actor" didn`t know enough about climate science to claim authority. The two sparred over the the most appropriate response to extreme weather events and global warming on NBC`s Meet the Press, and disagreed on the scientific consensus regarding climate change. Rep. Blackburn maintained that there is not consensus in the...
