Scientists who predicted a few years ago that Arctic summers could be ice-free by 2013 now say summer sea ice will probably be gone in this decade.

Now they are working with a new computer model ….  that produces a “best guess” date of 2016.

There are many kinds of truth. Al Gore was poleaxed by an inconvenient one yesterday.

The former US Vice-President, who became an unlikely figurehead for the green movement after narrating the Oscar-winning documentary An Inconvenient Truth, became entangled in a new climate change “spin” row.

Mr Gore, speaking at the Copenhagen climate change summit, stated the latest research showed that the Arctic could be completely ice-free in five years.

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.”

Because climate change in the Arctic region is occurring faster and to a greater extent than anywhere else, the Arctic Ocean may be ice-free for a short period of time as early as the summer of 2015, according to the 2009 Arctic Marine Shipping Assessment Report completed by the eight Arctic Council Nations.

Polar ice cap melting away in 2008 ?

The latest salvo comes courtesy of Xinhua, which reports that Olav Orheim, the head of the Norwegian International Polar Year Secretariat, is placing his money on this summer. Noting that its ice sheet had reached a historical low of 3m sq. km last summer – it covered around 7.5m sq. km as recently as 2000 – Orheim told Xinhua that “if Norway’s average temperature this year equals that in 2007, the ice cap in the Arctic will all melt away.” Barring this disaster, Orheim predicted that excess carbon dioxide emissions and higher average temperatures would unpredictably alter the region’s fragile ecosystems. On a separate note, he said that Asia would likely be hardest hit by rising sea levels, estimating that a one meter rise would affect “nearly 100 million people on an area of 800,000 square km in Asia and direct economic loss will amount to 400 billion U.S. dollars.”

There is a lot more sea ice this month around Alaska and Siberia than there was in May, 1989.

NASA expert Jay Zwally said that the Arctic may be ice free in about 14 weeks.

This planetary energy imbalance is itself now sufficient to melt ice corresponding to one meter of sea level rise per decade

He must be thinking about the 400,000 nuclear bombs of added heat going into the ocean every day. Each time one explodes, it whispers “nutcase” in Hansen’s ear.

The Earth has been facing imminent doom since Earth day, 1970. The door to rescue the planet is always about to close.

While global negotiations have slowed since the high-intensity period over the last three years (in Copenhagen, Cancun, and Durban), that doesn’t mean we can afford for action to slow down.  After all, as the International Energy Agency just pointed out the door for avoiding the greatest impacts is quickly closing.

Hansen is about to close the door.

Barack Obama has only four years to save the world. That is the stark assessment of Nasa scientist and leading climate expert Jim Hansen who last week warned only urgent action by the new president could halt the devastating climate change that now threatens Earth. Crucially, that action will have to be taken within Obama’s first administration, he added.

Is there any way these geniuses can just shut the door, leave it closed, go drink a beer and STFU?
