Next Ice Age delayed by Global Warming

Science
Humans are putting the brakes on the next ice age, according to the most extensive study to date on Arctic climate change.

Previously, researchers had looked at Arctic temperature data that went back just 400 years. (See photos of how climate change is transforming the Arctic.)

That research showed a temperature spike in the 20th century, but it was unclear whether human-caused greenhouse gas emissions or natural variability was the culprit, noted study co-author Gifford Miller of the Institute of Arctic and Alpine Research at the University of Colorado, Boulder.

By looking even farther back in time, Miller and colleagues' newest study reveals that the 20th century's abrupt warming in fact interrupted millennia of steady cooling.


This suggests that the Fallen Angels idea of Pournelle,Niven and Flynn may not be that inaccurate, after all. (In the novel, extreme efforts at stopping global warming results in an Ice Age instead). However, I think we've gone so far into global warming that even if we stopped pumping CO2 into the atmosphere today (impossible, unless we all were transported off the planet en masse), the climate change we have wrought would still take decades, if not a century, to still run.

This report is NOT an excuse and a justification to stop doing anything about global climate change. It DOES give me, though, yet again, another SF novel idea...

Smithsonian Alters Climate Exhibition

Published: May 22, 2007
The Smithsonian Institution toned down an exhibition on Arctic climate change, fearing that it would anger Congress and the Bush administration, a former museum administrator said. The official text of the exhibition was rewritten to minimize and add uncertainty about the relationship between global warming and people, said the former official, Robert Sullivan, who was associate director in charge of exhibitions at the National Museum of Natural History. Officials omitted scientists’ interpretations of some research and let visitors draw their own conclusions from the data, Mr. Sullivan said. In addition, graphs were altered “to show that global warming could go either way,” he said. Museum officials denied that political concerns had influenced the exhibition, saying the changes were made to increase objectivity.
