“Examination of several proxy records (e.g., sediment cores) of sea ice indicate ice-free or near ice-free summer conditions for at least some time during the period of 15,000 to 5,000 years ago”

The Polar Bears must gave gone extinct (or mated with Grizzlies.)

The high priest of the hotheads is NASA’s James Hansen, who preaches that, unless we dial back to 350ppm, we will lose, within a hundred years’ time, the vast majority of Greenland’s ice, which will raise sea levels about 20 feet. Hansen has testified that he thinks this could happen within a hundred years.

The hothead theory is that the ice on that gigantic island is much less stable than previously thought, and that with a tad more warming, lakes will form in the summer, drain thousands of feet down to the bedrock, and lubricate the flow to the ocean. It quickly melts, submerging a lot of Florida and Manhattan. The Washington Monument becomes an island.

Greenland has 10,000 feet of glacial ice above sea level, which is about 1/4 of the density of the granite underneath it. In order to maintain isostatic equilibrium, the ground underneath the ice sheet must be depressed about 2,500 feet in the center. In other words, the land surface of Greenland must be somewhat bowl shaped.

Additionally, Greenland has large mountain ranges which block the movement of deeper ice. The point being that the ice sheet can not slide off into the ocean as a block – because things don’t slide uphill and they don’t slide through mountain ranges.

Greenland’s glaciers move towards the ocean because snow builds up in the interior (above the mountain tops) and the excess weight causes the ice to flatten and spread outwards.

Hansen is often described by the press as the world’s greatest climatologist.

James Hansen, March 31

Based on sub­sur­face ocean tem­pera­tures, the way these have pro­gres­sed the past sever­al months, and com­parisons with de­velop­ment of prior El Niños, we be­lieve that the sys­tem is mov­ing toward a strong El Niño start­ing this summ­er. It’s not a sure bet, but it is pro­b­able.

The ice is thicker and temperatures are cold.

Over the past several years, the proportion of older, thicker Arctic sea ice has fallen, leaving polar waters dominated by thinner ice that forms in the fall and melts in the summer.

This year the older, thicker ice has increased somewhat over last year

Older ice has been increasing for the last three years. Apparently SA lacks access to the Internet

Climate change negotiations accomplish little in Bangkok
Apr 8, 2011

Bangkok – International negotiations on climate change held this week failed to tackle a host of issues that are pitting developed against developing nations, the chief UN climate change official said Friday.
A session of the UN Framework Convention on Climate Change, which is to wrap up late Friday, has left much to be discussed before a climate change summit planned for the end of the year in Durban, South Africa.
Executive Secretary Christiana Figueres acknowledged that little had been accomplished to further the progress made last year at the climat summit in Cancun, Mexico.
For instance, the talks failed to put agriculture as well as maritime and aviation emissions on this year’s work agenda, she said.
Other unsolved issues included agreements to work on global goals for emissions cuts, reviews of past cuts and the legal structure of a climate regime.
‘All of these big-picture issues did not find space in Cancun, and it is clear after this meeting that they remain on the table,’ Figueres said.
The week-long Bangkok talks to set the agenda for the next session of climate discussions in June in Bonn, Germany, and the Durban meeting were expected to continue late into the night Friday, their final day.
