Hottest Arctic Hype
By Paul Homewood
There has been a concerted effort in the last few days to run the latest Arctic scare story, such as this one in the Telegraph:
The Arctic shattered heat records in the past year as unusually warm air triggered massive melting of ice and snow and a late fall freeze, US government scientists said on Tuesday.
The grim assessment came in the Arctic Report Card 2016, a peer-reviewed document by 61 scientists around the globe issued by the US National Oceanic and Atmospheric Administration.
The NOAA report covers from October 2015 to September 2016, a period it said the Arctic’s average annual air temperature over land was the highest on record.
The use of the word “heat”, has become prevalent lately, all designed to put slightly warmer weather into a bad light. All I can say to the writer of this article is that, if they really think it is hot in the Arctic, let them go for a swim there.
But how warm has it been up there this year?
Atmospheric temperatures, according to UAH,are the highest since 1979, running at 1.16C above the 1981-2010 mean.
HADCRUT surface data, however, does not suggest any unusual warmth this year. (Figures are up to October 2016).
And looking back through the 20thC, spikes in temperature of this magnitude are not all unusual around the Arctic, as we saw during the 1920s and 30s.
Actual temperatures per GHCN V2 as at 2011.
Meanwhile sea ice extent, despite growing more slowly than usual during the autumn, is now back to the level of recent years.
The Greenland ice sheet has been accumulating at way above normal rates since the summer:
And snow extent in the Northern Hemisphere has also been well above average this autumn, as it has been for most recent years.
Nothing is actually happening that justifies the apocalyptic headlines published by much of the media around the world, instigated in turn by NOAA.
