Arctic sea ice "recovers" to its 6th-lowest extent in millennia
2013-09-19 05:58:00| Climate Ark Climate Change & Global Warming Newsfeed
Guardian: As Suzanne Goldenberg reported in The Guardian yesterday, Arctic sea ice appears to have reached its annual minimum extent, at approximately 5.1 million square kilometers. This is the 6th-lowest extent since the satellite record began in 1979. But in fact, scientists have also reconstructed Arctic sea ice extent data much further into the past. For example, Drs. Walsh & Chapman from the University of Illinois have estimated sea ice extent as far back as the year 1870 using a vast array of data...
Global Warming Could Explain Exponential Sea Ice Growth

RedOrbit: In a bit of strange and unprecedented good news, it was recently discovered Antarctic sea ice is growing at record rates. This is definitely odd, of course, because the air and the oceans have been getting warmer in the area. There is now more sea ice in Antarctica than there had been in the 1970s, a data point which University of Washington (UW) researcher Jinlun Zhang wanted to unpack and investigate. According to his National Science Foundation-funded research, global warming might be responsible...
Stronger Winds Behind Mysterious Growth in Antarctic Sea Ice, Study Suggests

Nature World News: Strong westerly winds may be the reason Antarctic sea ice continues to expand in spite of a warming climate, a new study shows. Even as Arctic sea ice is hitting record lows, the Antarctic has been reaching record highs, baffling researchers and fueling arguments posed by global warming skeptics. "The overwhelming evidence is that the Southern Ocean is warming," Jinlun Zhang, an oceanographer at the University of Washington's Applied Physics Laboratory, said in a statement. "Why would sea ice...
The Vital Long View in Tracking Diminishing Arctic Sea Ice

New York Times: With the annual pullback of Arctic Ocean sea ice at an end, its clear that this years retreat is nowhere near the satellite-era record set in 2012, but its also clear that there is still a long-term trajectory toward a largely open-water Arctic in summers in coming decades. The image above is from The Cryosphere Today, a valuable Website maintained by William Chapman and others at the University of Illinois, Urbana-Champaign. The National Snow and Ice Data Center has not quite officially called...
Estimates put Arctic ice melting by 2050

Financial Times: The Arctics summer sea ice is set to nearly vanish in less than 40 years, according to the final draft of a sweeping UN climate change report that sharply revises past estimates of how fast the icy north is melting. A nearly ice-free Arctic Ocean in September before mid-century is likely, says the draft seen by the Financial Times of the first large-scale study in six years by the Intergovernmental Panel on Climate Change. The retreating ice is encouraging for Arctic nations such as Russia,...
