A Geological Perspective on Arctic Sea Ice Extent (AKA PIP25: “Miracle on Ice”)

Guest review article by David Middleton We’re often bombarded with headlines line this: 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. The problem with headlines like this is the fact that the “record” only dates back to 1979.…

‘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…
