The Awful Terrible Horrible Global Sea Ice Crisis

Guest Post by Willis Eschenbach My examination of objects cryospherical continues. In my last post, The Size of Icy Reflections, I showed that a change of 10% in the global sea ice area translates into a global average of a 0.1 watt per square metre (W/m2) change in reflected sunlight. In this post, I’ll look at what…

The Size of Icy Reflections

Guest Post by Willis Eschenbach In my continuing wanderings through the regions cryospherical, I find more side roads than main highways. In my last two posts here and here, I discussed the curious inverse relationship between temperature and ice accumulation rates in Greenland and Antarctica. Wanting to understand the changes in the polar oceans that occur when…

The Ice Was All Between

Guest Post by Willis Eschenbach I do my best to maintain my sense of awe regarding the things I study. I’ve had the good fortune in my life to be a commercial fisherman on the Bering Sea, and to voyage and fish on the edges of the Arctic ice. To me, sea ice, whether fixed…

DMI apologizes for their disappeared sea-ice graph debacle

Earlier this week, I published a post titled: DMI disappears an inconvenient sea ice graph . Some of the usual folks who police any sea ice discussion went ballistic over the post, and in some ugly blog posts of their own, suggested I and others were engaging in Lewandowsky inspired “conspiracy ideation”. While others may have been,…

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…
