Arctic Ocean to be ice-free during summers before 2050

Mother Nature Network: By the time today's babies graduate college, there's a very good chance they could celebrate with a cruise across the North Pole. That's according to the latest study on Arctic summer sea ice, the frozen pack that lingers through the Northern Hemisphere summer. In past decades, there's been less summer ice, and it's growing thinner. The research, published online Feb. 21 in the journal Geophysical Research Letters, says major sea ice loss could come within a decade or two, though some ice will...

Study: Arctic Summers Warmest in 600 Years

2013-04-12 21:00:00| Climate Ark Climate Change & Global Warming Newsfeed

Climate Central: The Arctic has seen warmer summers over the past two decades than at any time in the past 600 years, according to a study published this week in the journal Nature. The study uses a sophisticated statistical approach, known as Bayesian modeling, to show that the extremely warm summers in high northern latitudes are evidence of an overall warming trend, rather than just a temporary fluctuation in an otherwise unchanging climate. Thats a crucial distinction: a natural fluctuation might reverse before...

Study: Natural causes, not human activity, behind last summer's Plains drought

2013-04-12 20:44:00| Climate Ark Climate Change & Global Warming Newsfeed

CNN: Extreme natural events, not man-made climate change, led to last summer's historic drought in the Great Plains, a new federal study said Friday. Drought occurred in six Plains states between last May and August because moist Gulf of Mexico air "failed to stream northward in late spring," and summer storms were few and stingy with rainfall, said a report by the National Oceanic and Atmospheric Administration. "Neither ocean states nor human-induced climate change, factors that can provide long-lead...
