New research suggests that West Antarctica has warmed much more than scientists have thought over the last half century, an ominous finding given that the huge ice sheet there may be vulnerable to long-term collapse, with potentially drastic effects on sea level.
A paper released Sunday by the journal Nature Geoscience found that the temperature at a research station in the middle of West Antarctica has warmed by 4.4 degrees Fahrenheit since 1958. That is roughly twice as much as scientists previously thought and three times the overall rate of global warming, making central West Antarctica one of the fastest-warming regions on earth.
“The surprises keep coming,” said Andrew J. Monaghan, a scientist at the National Center for Atmospheric Research in Boulder, Colo., who took part in the study. “When you see this type of warming, I think it’s alarming.”

Much of the warming discovered in the new paper happened in the 1980s, around the same time the planet was beginning to warm briskly. More recently, Dr. Bromwich said, the weather in West Antarctica seems to have become somewhat erratic. In the summer of 2005, the interior of West Antarctica warmed enough for the ice to undergo several days of surface melting.
Dr. Bromwich is worried that this could eventually become routine, perhaps accelerating the decay of the West Antarctic ice sheet, but the warming is not fast enough for that to happen right away. “We’re talking decades into the future, I think,” Dr. Bromwich said.

West Antarctica Warming Faster Than Thought, Study Finds

Every single prediction has underestimated the effects altering our atmosphere will have.

Be prepared to take care of yourselves and your family in the decades to come. The sheer magnitude of resouces that will need to be brought to bear to fix the atmosphere, and the changes in lifestyle it will require of all of us is mind boggling. There will be nothing left over to rescue us from simple disasters.
