They say that sea level rise rates are underestimated.
THE Greenland ice sheet melted at the fastest rate since 1958 last year while Arctic sea ice shrank to the third-smallest area on record, an Obama administration report on global climate reveals.
‘This report makes one thing very clear: global warming isn’t coming, it’s already here,” Democrat Representative Edward Markey of the House Natural Resources Committee, said. ”The slow boil of the Earth is now rolling, and now we need to find ways to turn down the heat, and fast.” The Greenland ice sheet melted at the fastest rate in 53 years, with the melt area about 8 per cent larger than the record set in 2007, according to the report.
”We’re continuing to closely track these indicators because it’s quite clear that the climate of the past can’t be assumed to represent the climate of the future,” Thomas Karl, director of NOAA’s National Climatic Data Centre in Asheville, North Carolina, said.
In March, an American National Aeronautics and Space Administration-funded study said ice losses in Greenland and Antarctica were accelerating, suggesting the United Nations’ estimates for sea-level rise are too conservative. A UN panel on climate change predicted in 2007 that global sea levels would rise by 18 to 59 centimetres this century.
I’ll bite.. where’s the ice melting to? Evaporating straight into the atmosphere? Underground?
They can “estimate” sea-level changes all they want.. observations trump them every time… which means back to the “estimation” drawing board.
And yet, the warmest year records seem OLD … 191x, 192x,193x
1929 seems to have been the warmest year ever.

Among those records that go back that far … 1929 is it.

“A paper published last month in the journal Climate of the Past illustrates three different temperature reconstructions of southwest Greenland, which show temperatures were higher than the present in the 1930’s, 1940’s, 1700’s, and multiple other times over the past 700 years when CO2 levels were extremely safe”
From Aunty ‘the Age’, more truth in reporting (not).
I notice today that the Russian ‘Drifting station NP-38’ is still drifting – s.s.temp 1.6degC (it is after all just past Mid summer) and is above 82deg lat. N. Hemisphere – Arctic.
And down in the balmy south (Antarctica) the sea ice has nearly completely surrounded the southern continent.
McMurdo Base (US) at edge of Ross ice shelf, temp -25degC, Wind chill -31degC today.
Amundsen-Scott base at South Pole, temp -68.1degC. Wind chill -84.6degC today.
Amundsen-Scott has at least 2 miles of ice beneath, the Icecube Neutron Telescope is 1.5kms – 2.5kms beneath the ice surface, completed recently at around $78million dollars plus ongoing costs.
Antarctica isn’t going anywhere soon.
Artic ice whether it melts or not has zero effect on sea level as its floating. Solids displace their mass in a fluid.
Ed Markey is a brainless boob. Sorry for the ad hominem but truth is truth.
