by Alan Longhurst Natural climate variability in the polar regions. If our planet had been designed with comparative high-latitude studies in mind, it couldn’t have been better arranged than it is. The 700N parallel encloses extensive continental regions that were … Continue reading →

A review of the relationship between the solar input to high latitudes and the global ice volume over the past 2.7 million years.

Satellite observations indicate that the average Arctic sea ice extent has generally decreased since the start of the satellite records in October 1978. Is this period long enough to assess whether the current sea level trend is unusual, and to what extent the decline is caused by humans?

We conclude that the observed cooling over central Eurasia was probably due to a sea-ice-independent internally generated circulation pattern ensconced over, and nearby, the Barents–Kara Sea since the 1980s. — McCusker et al.

This year, as every year, there has been much excitement in the media about ‘catastrophic’ melting of Arctic sea-ice, run-away melting, tipping points, death spirals and “ice-free” summers.

Aitken et. al. in Nature newly comports to confirm 2015 fears about instability of the Totten Glacier in Eastern Antarctica. This could ‘suddenly’ raise sea level as much as 4 meters! (Or, based on the abstract, maybe only 0.9 meters in ‘modern scale configuration’, but over 2 meters [2.9-4] in unspecified other configurations).

Arctic sea ice extent has been anomalously low this winter.

A discussion of Section 8.3 of Alan Longhurst’s book Doubt and Certainty in Climate Science.
For context on the topic of the variability of Arctic climate, see these previous blog posts:

The Washington Post has this dramatic headline: Global warming is now slowing down the circulation of the ocean with potentially dire consequences.

I have prepared two new talks on sea ice to present in Nanjing.
But first, some recent context on sea ice.
2014 sea ice minima
The last several years I have written a post on sea ice around the time of the Arctic sea ice minima
