Glaciers melting at runaway pace, new report says

The vast glaciers of western Antarctica are shrinking and losing ice to the sea at a runaway pace and have almost certainly “passed the point of no return,” according to new work by two separate teams of scientists. The likely result: a rise in global sea levels of four feet or more in the coming centuries, says research made public Monday by scientists at the University of Washington, the University of California-Irvine and NASA’s Jet Propulsion Laboratory. “It really is an amazingly distressing situation,” says Pennsylvania State University glaciologist Sridhar Anandakrishnan, who was not affiliated with either study. “This is a huge part of West Antarctica, and it seems to have been kicked over the edge.”

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

Autumn freeze coming 11 days later in some regions

FRISCO — 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 ever more of the sun’s energy in summer, leading to an ever later appearance of sea ice in the autumn. In some regions, autumn freeze-up is occurring up to 11 days per decade later than it used to.
