Arctic ice grows darker and less reflective
2013-08-06 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
New Scientist: Arctic ice is losing its reflective sheen. It's common knowledge that each summer, more and more of the ice melts leaving the dark waters of the ocean uncovered a process that accelerates global warming by reducing the amount of solar radiation reflected back into space. Now it turns out that the surviving sea ice is also becoming darker and less reflective. For the first time, a detailed analysis of 30 years of satellite data for the Arctic Ocean has quantified how much the albedo, or reflectivity,...

Bloomberg: Royal Dutch Shell Plc (RDSA)s oil spill plans for drilling in Alaskas Beaufort and Chukchi seas dont violate environmental laws, a federal judge in Anchorage ruled in rejecting a challenge by conservation groups. The U.S. Interior Departments approval process wasnt flawed or based on erroneous assumptions and the approvals dont violate the Endangered Species Act, the Clean Water Act or other environmental laws, U.S. District Judge Ralph Beistline ruled yesterday. Shell halted operations off...

Loss of sea ice affects all Arctic life: Study
2013-08-03 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Canadian Press: A review of the latest research on the Arctic says the accelerating loss of sea ice is kicking the legs out from under the entire northern dinner table with consequences for large animals and tiny plants alike. "We're losing all the things that life depends on," said Ian Stirling, an adjunct professor at the University of Alberta and one of the co-authors of a study published Thursday in the prestigious journal Science. The paper reviews dozens of recent studies on the Arctic in an attempt...
Prolonged Heat Wave Leaves Russian Arctic Vulnerable to Wildfires
2013-08-02 18:31:00| Climate Ark Climate Change & Global Warming Newsfeed
Yale Environment 360: An enduring high-pressure weather system over the Russian Arctic has led to a prolonged heat wave, creating conditions for another surge in wildfires a year after a particularly extreme wildfire season. NASA scientists say that a so-called blocking high system in which rain-bearing systems are blocked from moving west to east has caused temperatures to reach 90 degrees F (32 degrees C) in the northern city of Norlisk, where daily highs in July typically average 61 degrees F (16 degrees C)....
