Al Gore's Admits His Ice Cap Predictions Were Bogus

Former Vice President Al Gore made a startling announcement at the UN Climate Conference today:
New computer modeling suggests the Arctic Ocean may be nearly ice-free in the summertime as early as 2014, Al Gore said Monday at the U.N. climate conference. This new projection, following several years of dramatic retreat by polar sea ice, suggests that the ice cap may nearly vanish in the summer much sooner than the year 2030, as was forecast by a U.S. government agency eight months ago. "It is hard to capture the astonishment that the experts in the science of ice felt when they saw this," said former U.S. Vice President Gore, who joined Scandinavian officials and scientists to brief journalists and delegates. It was Gore's first appearance at the two-week conference.
There was one thing that Gore left out of his stunning statement, it was wrong !! So says the scientist who gave Gore the numbers. And while the Press is still reporting on Gore's stunning numbers, Gore's office admitted that the percentage he quoted in his speech was from an old, ballpark figure.
In his speech, Mr Gore told the conference: “These figures are fresh. Some of the models suggest to Dr [Wieslav] Maslowski that there is a 75 per cent chance that the entire north polar ice cap, during the summer months, could be completely ice-free within five to seven years.
However, the climatologist whose work Mr Gore was relying upon dropped the former Vice-President in the water with an icy blast.

“It’s unclear to me how this figure was arrived at,” Dr Maslowski said. “I would never try to estimate likelihood at anything as exact as this.”

Mr Gore’s office later admitted that the 75 per cent figure was one used by Dr Maslowksi as a “ballpark figure” several years ago in a conversation with Mr Gore.

Gore's "snafu" just adds more doubt on the conference coming soon after the  hacked e-mails from the University of East Anglia’s Climate Research Unit, suggests that scientists had manipulated data to strengthen their argument that human activities were causing global warming.

Mr Gore is not the only titan of the world stage finding Copenhagen to be a tricky deal.

World leaders — with Gordon Brown arriving tonight in the vanguard — are facing the humiliating prospect of having little of substance to sign on Friday, when they are supposed to be clinching an historic deal.

Meanwhile, five hours of negotiating time were lost yesterday when developing countries walked out in protest over the lack of progress on their demand for legally binding emissions targets from rich nations. The move underlined the distrust between rich and poor countries over the proposed legal framework for the deal.

Last night key elements of the proposed deal were unravelling. British officials said they were no longer confident that it would contain specific commitments from individual countries on payments to a global fund to help poor nations to adapt to climate change while the draft text on protecting rainforests has also been weakened.

Even the long-term target of ending net deforestation by 2030 has been placed in square brackets, meaning that the date could be deferred. An international monitoring system to identify illegal logging is now described in the text as optional, where before it was compulsory. Negotiators are also unable to agree on a date for a global peak in greenhouse emissions.

Gore's speech was roundly criticised by upset members of the climate science community. “This is an exaggeration that opens the science up to criticism from sceptics,” said Professor Jim Overland, a leading oceanographer at the US NOAA. “You really don’t need to exaggerate the changes in the Arctic.”

Others said that, even if quoted correctly, Dr Maslowski’s six-year projection for near-ice-free conditions is at the extreme end of the scale. Most climate scientists agree that a 20 to 30-year timescale is more likely for the near-disappearance of sea ice.

“Maslowski’s work is very well respected, but he’s a bit out on a limb,” said Professor Peter Wadhams, a specialist in ocean physics at the University of Cambridge.

Dr Maslowki, who works at the US Naval Postgraduate School in California, said that his latest results give a six-year projection for the melting of 80 per cent of the ice, but he said he expects some ice to remain beyond 2020.

He added: “I was very explicit that we were talking about near-ice-free conditions and not completely ice-free conditions in the northern ocean. I would never try to estimate likelihood at anything as exact as this,” he said. “It’s unclear to me how this figure was arrived at, based on the information I provided to Al Gore’s office.”

Richard Lindzen, a climate scientist at the Massachusets Institute of Technology who does not believe that global warming is largely caused by man, said: “He’s just extrapolated from 2007, when there was a big retreat, and got zero.”
