Do NOT miss this: More climate realism from Andy Revkin

On Arctic Ice and Warmth, Past and Future - NYTimes.com

But even as I push for an energy quest that limits climate risk, I’m not worried about the resilience of Arctic ecosystems and not worried about the system tipping into an irreversibly slushy state on time scales relevant to today’s policy debates. This is one reason I don’t go for descriptions of the system being in a “death spiral.”

The main source of my Arctic comfort level — besides what I learned while camped with scientists on the North Pole sea ice — is the growing body of work on past variability of conditions in the Arctic. The latest evidence of substantial past ice variability comes in a study in the current issue of Science. The paper, combining evidence of driftwood accumulation and beach formation in northern Greenland with evidence of past sea-ice extent in parts of Canada, concludes that Arctic sea ice appears to have retreated far more in some spans since the end of the last ice age than it has in recent years.

Michael MacCracken, a veteran climate modeler and chief scientist at the Climate Institute, noted on the Google group on geo-engineering that this new paper adds credence to proposals for an Arctic focus for managing incoming sunlight as a way to limit greenhouse-driven impacts. (Personally, I don’t see this kind of effort going anywhere unless and until climate impacts trend toward worst-case outcomes.)
