The headline is a quote by Dr. Judith Curry from a David Rose article in the Sunday Mail: Stunning satellite images show summer ice cap is thicker and covers 1.7million square kilometres MORE than 2 years ago…despite Al Gore’s prediction it would be ICE-FREE by now.
The speech by former US Vice-President Al Gore was apocalyptic. ‘The North Polar ice cap is falling off a cliff,’ he said. ‘It could be completely gone in summer in as little as seven years. Seven years from now.’
Those comments came in 2007 as Mr Gore accepted the Nobel Peace Prize for his campaigning on climate change.
But seven years after his warning, The Mail on Sunday can reveal that, far from vanishing, the Arctic ice cap has expanded for the second year in succession – with a surge, depending on how you measure it, of between 43 and 63 per cent since 2012.
To put it another way, an area the size of Alaska, America’s biggest state, was open water two years ago, but is again now covered by ice.
The most widely used measurements of Arctic ice extent are the daily satellite readings issued by the US National Snow and Ice Data Center, which is co-funded by Nasa. These reveal that – while the long-term trend still shows a decline – last Monday, August 25, the area of the Arctic Ocean with at least 15 per cent ice cover was 5.62 million square kilometres.
This was the highest level recorded on that date since 2006 (see graph, right), and represents an increase of 1.71 million square kilometres over the past two years – an impressive 43 per cent.
Other figures from the Danish Meteorological Institute suggest that the growth has been even more dramatic. Using a different measure, the area with at least 30 per cent ice cover, these reveal a 63 per cent rise – from 2.7 million to 4.4 million square kilometres.
The satellite images published here are taken from a further authoritative source, the University of Illinois’s Cryosphere project.
They show that as well as becoming more extensive, the ice has grown more concentrated, with the purple areas – denoting regions where the ice pack is most dense – increasing markedly.
Crucially, the ice is also thicker, and therefore more resilient to future melting. Professor Andrew Shepherd, of Leeds University, an expert in climate satellite monitoring, said yesterday: ‘It is clear from the measurements we have collected that the Arctic sea ice has experienced a significant recovery in thickness over the past year.

Indeed, and the way things are going, it looks like WUWT (and Wang) will be closer to the final September Average for Sea Ice than any of the other forecast players in the ARCUS Sea Ice prediction Network:
