Inconvenient: iceberg calving helps ‘carbon sequestration’ and is ‘helping to slow global warming’

From the UNIVERSITY OF SHEFFIELD and the department of “unknown negative feedbacks” comes this interesting study. While there have been numerous claims that warmer Polar temperatures (due to posited global warming effects) will cause more iceberg calving, I’m sure it will come as quite a shock to those same folks when they discover that there’s…

Claim: Melting sea ice increases Arctic precipitation, complicates climate predictions

From DARTMOUTH COLLEGE and the “Reports of the demise of Arctic Sea Ice are greatly exaggerated” department HANOVER, N.H. – The melting of sea ice will significantly increase Arctic precipitation, creating a climate feedback comparable to doubling global carbon dioxide, a Dartmouth College-led study finds. “The increases of precipitation and changes in the energy balance may…

Micro-critters Rule!

A layman’s musings about ecology, and the possibility that, while man may rule the fate of whooping cranes, far smaller creatures may rule the fate of sea-ice. Guest essay by Caleb Shaw Sometimes, as my mind’s eye wanders over the Arctic Ocean, I am drawn ashore to contemplate wonders of the Tundra. I try to…
