Some surprises in polar bear sea ice habitat at mid-October 2020

Arctic sea ice has been growing steadily since the minimum extent was reached a month ago, with shorefast ice now developing along the Russian and Alaskan coastlines as ice cover expands in the Central Canadian Arctic. So while it’s true that the main pack of Arctic ice is far from the Russian shoreline, rapidly developing shorefast ice will allow bears to begin hunting seals long before ice in the central Arctic Basin reaches the Siberian shore, as they do in Western and Southern Hudson Bay every fall.

A Geological Perspective of Polar Bears

Guest “geological perspective” by David Middleton A Popular Narrative Polar bears (Ursus maritimus) are the poster child for the impacts of climate change on species, and justifiably so. To date, global warming has been most pronounced in the Arctic, and this trend is projected to continue. There are suggestions that before mid-century we could have…

‘Arctic sea ice continues its downward spiral’… Warmunists keep using that word. I do not think it means what they think it means.

Guest drive-by by David Middleton NEWS 27 SEPTEMBER 2018 Arctic sea ice continues its downward spiral At 4.6 million square kilometres in coverage, this year’s sea ice minimum is the sixth lowest on record. Arctic sea-ice cover following this summer’s melt was the sixth lowest on record, the US National Snow and Ice Data Center…

How Much Sunlight Actually Enters The System?

Guest Post by Willis Eschenbach There’s a new study in PNAS, entitled “Observational determination of albedo decrease caused by vanishing Arctic sea ice” by Pistone et al. Let me start by registering a huge protest against the title. The sea ice is varying, it isn’t “vanishing”, that’s just alarmist rhetoric that has no place in…

New PNAS paper claims Arctic planetary albedo dropped significantly, yet recent CERES data shows no significant change

From PNAS: Direct satellite observation reveals that the Arctic planetary albedo, a measure of reflectiveness, decreased from 0.52 to 0.48 between 1979 and 2011, a change in albedo that corresponds to a climate forcing 25% as large as that due to changes in atmospheric carbon dioxide concentrations over the same time period, according to this…
