Latest admission from NSIDC on forecasting sea ice extent is a far cry from ‘Arctic death spriral’

Remember the famous claims about the ‘Arctic death spiral‘? It seems their language is a bit more realistically moderated now that they’ve blown a couple of forecasts. Seasonal Arctic summer ice extent still hard to forecast, study says Will next … Continue reading

New study shows Arctic sea ice extent ~6000 years ago was much less than today

This is interesting, somehow the Earth managed to reduce a good portion of the Arctic Ice Cap during the Holocene Climate Optimum from approximately 10,000-6,000 years ago without the help of the industrial revolution, fossil fuels, or automobile emissions. This … Continue reading

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 … Continue reading

Claim: Dramatic thinning of Arctic lake ice cuts winter ice season by 24 days

Arctic lakes have been freezing up later in the year and thawing earlier, creating a winter ice season about 24 days shorter than it was in 1950, a University of Waterloo study has found. But, I don’t think they are … Continue reading

Claim: Arctic warmth unprecedented in 44,000 years

Using radiocarbon dating, new research in Geophysical Research Letters has calculated the age of relic moss samples that have been exposed by modern Arctic warming. Results claim that temperatures in the Arctic are warmer than during any sustained period since … Continue reading

Remember the Arctic cyclone that busted up sea ice in 2012? It seems such storms are more common than previously thought

News media back then seemed to think this was a new thing, and downplayed the role of the cyclone is breaking up sea ice, preferring to attribute it to the omnipotent global warming. Apparently it’s just business as usual for … Continue reading

No pattern found in Northern Hemisphere atmospheric blocking and weather extremes

A new paper in press at GRL (Barnes et al 2014) suggests that the idea of “blocking” patterns being on the increase due to climate change factors such as sea ice have no statistically significant  component. As readers may know, … Continue reading
