The Times Comprehensive Atlas of the World publishers are reviewing the latest edition, because of questions over whether its depiction of Greenland is accurate.

HarperCollins has already apologised for wrongly claiming that 15 per cent of Greenland’s ice – the equivalent of the UK and Ireland – had melted since 1999.

Scientists said there were glaciers where the atlas showed ice-free conditions and new land and that the change in the size of Greenland’s ice shelf was actually far smaller.

HarperCollins will produce another map of Greenland, which “reflects all the latest data”.

But the publisher said there was “no clarity” in the scientific and cartographic community on the country’s ice cover.

The company made a statement that said: “On reflection and in discussion with the scientific community, the current map does not make the explanation of this topic as clear as it should be.

“We are now urgently reviewing the depiction of ice in the atlas against all the current research and data available, and will work with the scientific community to produce a map of Greenland which reflects all the latest data.

“We will then create an insert for the current atlas showing this map and also give an explanation of the situation and how we have mapped it.

“Any material generated as a result of this activity will also be made available online and incorporated into the atlas.'

Dr Poul Christoffersen, a glaciologist at the Scott Polar Research Institute at the University of Cambridge, said: 'We compared recent satellite images of Greenland with the new map and found that there are in fact still numerous glaciers and permanent ice cover where the new Times atlas shows ice-free conditions and the emergence of new lands.

“Furthermore, the low-lying fringe of the main ice sheet appears to be shown as land, not ice. We concluded that a sizeable portion of the area mapped as ice-free in the atlas is clearly still ice-covered.”
He said Greenland’s ice sheet was losing ice volume at a rate of around 0.1 per cent over 12 years.
