Tim Flannery mentioned this at the IAI Conference.
He said the Arctic sea ice has not even frozen this year (winter) according to Norwegian fly-overs..
He also said the Greenland ice sheet is moving, setting of many earthquakes (Richter 5-5.5)

One report noted there was less Arctic sea ice in April than had ever been recorded that month since satellite imagery of the northern ocean began in 1979. Another found that the melting of the Arctic ice cap is proceeding faster than anyone expected.
That second finding -- announced jointly by scientists at the National Snow and Ice Data Center and the National Center for Atmospheric Research -- concludes that all the summer Arctic sea ice should disappear "about 30 years" sooner than mainstream climate models earlier predicted.
The Intergovernmental Panel on Climate Change, widely regarded as the gold standard for such projections, had estimated that summer sea ice in the Arctic probably declined at a rate of 2.5 percent a decade from 1953 to 2006. At that rate, the IPCC said, the summer ice cap would disappear sometime between 2050 and next century.
That estimate reflected the average of 18 separate IPCC climate scenarios, the most pessimistic of which placed the rate of ice shrinkage at 5.4 percent a decade.
But newly available data, "blending early aircraft and ship reports with more recent satellite measurements," show that the September ice actually declined at a rate of about 7.8 percent per decade from 1953 to 2006, the ice data center reported in a press statement.
"Because of this disparity, the shrinking of summertime ice is about 30 years ahead of the climate model projections," said NSIDC scientist and co-author Ted Scambos.
