The record fell over three weeks ago (see data). The reason I'm reporting it now is not just because I'm lazy or because the last time I called a maximum, I was heavily traumatized, but because I wanted to give WUWT and other fake skeptic blogs the chance to let their readers know about this new CT global sea ice area record, as they always invoke it to downplay the disappearance of Arctic sea ice. But somehow they're silent. How come, I say, how come?
I don't think combining the measurements of Arctic and Antarctic sea ice cover is particularly useful - it's like combining the weight of overweight and undernourished people and say: see, no hunger! - but it is an interesting statistic, and of course the trend is going down (albeit not as fast as Arctic SIA, due to a small positive trend in Antarctic SIA).
So here's the graph from Piotr Djaków's Pogoda i Klimat website:
And here are the numbers for the 2005-2012 period (in million km2):
- 2005: 22.051
- 2006: 21.776
- 2007: 21.234
- 2008: 22.177
- 2009: 21.003
- 2010: 21.043
- 2011: 20.902 (previous record)
- 2012: 20.650
46 vessels through Northern Sea Route
The 2012 navigation season on the Northern Sea Route is coming to an end. Never before have so many vessels taken the Arctic shortcut between Europe and Asia, and never before has so much cargo been transported along the route.
Although the season is not yet completely over – there are still two Finnish icebreakers in westbound transit from Alaska to Denmark – some remarks on the 2012 season can be made.
There has been a tenfold increase in the number of vessels using NSR during the last two years. This season 46 vessels have sailed the route, compared to 34 in 2011 and only four in 2010.
The total cargo transported on the NSR this year is 1 261 545 tons – a 53 percent increase from 2011, when 820 789 tons was shipped on the route.
25 of the vessels sailed NSR eastbound, starting from Murmansk, Arkhangelsk or Baydaratskaya Bay. 21 sailed in a westbound direction, a report from Rosatomflot reads. The report is given to BarentsObserver by the Centre for High North Logistics, an international knowledge hub on Arctic transport and logistics for businesses.
The BBC also had an article last week (hat-tip to Bas who sent me an e-mail):
Gas tanker attempts first winter Arctic crossing
A large tanker carrying liquified natural gas (LNG) is set to become the first ship of its type to sail across the Arctic.
The carrier, Ob River, left Norway in November and has sailed north of Russia on its way to Japan.
The specially equipped tanker is due to arrive in early December and will shave 20 days off the journey.
The owners say that changing climate conditions and a volatile gas market make the Arctic transit profitable.
