Yesterday we pointed out how an island shown on a map 50 years ago was cited (because it appears today and was finally given a name) as “proof” of Greenland ice melt. Now some heavy hitters are weighing in saying that the new Times Comprehensive Atlas of the World, has significant portions of its climate change and Greenland section all wrong. The Danish Meteorological Institute is now panning the atlas, and Richard Betts, who wrote sections of the atlas, is now complaining about misrepresentation by the Guardian. Atlasgate anyone?
From DMI (via Google Translate h/t Tom Nelson): Times Atlas represents the ice cap is too small
“There is no scientific evidence that the area of the Greenland ice sheet since 1999 has shrunk by 15% as the latest edition of the ‘Times Atlas shows,” says climate researcher Ruth Mottram, DMI.
In the latest edition of the British ‘Times Atlas’ is the area of Greenland’s ice sheet decreased by 15% during the period from 1999 to 2011. It must reflect the effects of global warming. But there is no scientific evidence for the claim that is overrated and not based on robust measurements.
‘Times Comprehensive Atlas of the World’ was first published in 1899 and is the standard reference atlas in large parts of the world.
The marked difference between the two ‘Times atlas’-map of Greenland for 1999 and 2011 is that the coastline especially on the east side is no longer covered by ice. The true picture is another.

The error may have occurred if katograferne from the ‘Times Atlas have used satellite images of Greenland to assess ice spatial distribution.
“When I look at satellite images of Greenland, it looks real enough dark along the coast, but that does not mean that the ice has disappeared” says climate researcher and continues: “The dark color is caused by dirt, dust and volcanic ash that makes the ice dark especially in Southeast Greenland. “
The area of the ice cap has diminished with the wrong ratios in the ‘Times Atlas, but it does not change that shrinks the ice in Greenland. In the period 2003 to 2008 are missing from 168 to 268 billion tons of ice, equivalent to four to six feet of water evenly over Denmark.
h/t to WUWT reader Peter Sørensen for flagging the DMI story in comments. Looking at that “dirty snow” in the photo above brings me back to the issue of black soot, which willmake the albedo change enough that even a little sun in below freezing temperatures can have an effect.
In the bishop hill comments section about this story.
Richard Betts is really annoyed, he wrote the climate change section for the Atlas.
He says that is not what he wrote, he is going to complain to the editors and the GUARDIAN
Richard Betts, is Head of Climate Impact for, UK Met Office, and an AR4 working gp 1 contributor, and a lead author for IPCC AR5, working group2
He sounds quite annoyed by media misinformation, and was twittering about it as well.
Richard Betts, Met Office & IPCC:
“I’m not happy. I wrote the climate change section for this Atlas and didn’t say any of that Greenland rubbish!
I have contacted the editors.
