Global warming: Study shows Arctic sea ice melt season lengthening five days per decade

Summit Voice: Averaged across the Arctic, the melt season is lengthening by five days each decade, with much of the change coming in the fall, when a warmer ocean simply takes longer to freeze than in the past. The extent of sea ice in the Arctic has been declining for the last four decades, said University College London researcher Julienne Stroeve, part of a research team that studied satellite data to track sea ice trends in the age of global warming. The data confirm that the Arctic Ocean absorbing...
Global Warming Felt to Deepest Reaches of Ocean

Newswise: In the mid-1970s, the first available satellite images of Antarctica during the polar winter revealed a huge ice-free region within the ice pack of the Weddell Sea. This ice-free region, or polynya, stayed open for three full winters before it closed. Subsequent research showed that the opening was maintained as relatively warm waters churned upward from kilometres below the oceans surface and released heat from the oceans deepest reaches. But the polynya -- which was the size of New Zealand --...

Global warming slowdown 'doesn't invalidate' climate change'
2014-02-27 01:16:00| Climate Ark Climate Change & Global Warming Newsfeed
Guardian: The slowdown in rising global surface temperatures is not a sign that climate change is no longer happening, the national science academies of the US and the UK have said. Publishing a guide on the state of climate change science, the National Academy of Sciences and the Royal Society said the short-term slowdown this century did not "invalidate" the long-term trend of rising temperatures caused by man-made climate change. "Despite the decadal slowdown in the rise of average surface temperature,...

Study questions whether global warming hiatus is for real
2014-02-26 11:29:00| Climate Ark Climate Change & Global Warming Newsfeed
CBC: The number of extremely hot days has been increasing steadily globally despite a "pause" in the rise of average surface temperatures over the past 15 years, a new study has found. "This analysis shows that not only is there no pause in the evolution of the warmest daily extremes over land but that they have continued unabated over the observational record," said the paper published Wednesday in Nature Climate Change. "Furthermore, the available evidence suggests that the most 'extreme' extremes...

Heat extremes increase despite global warming hiatus: scientists
2014-02-26 09:51:00| Climate Ark Climate Change & Global Warming Newsfeed
Reuters: Hot weather extremes have increased around the world in the past 15 years despite a slowdown in the overall pace of global warming, a study showed on Wednesday. Heat extremes are among the damaging impacts of climate change as they can raise death rates, especially among the elderly, damage food crops and strain everything from water to energy supplies. "Observational data show a continued increase of hot extremes over land during the so-called global warming hiatus," scientists in Switzerland,...
