Arctic Summers Ice-Free ‘by 2013’
BBC | 12/12/07 | Jonathan Amos

Scientists in the US have presented one of the most dramatic forecasts yet for the disappearance of Arctic sea ice.

Their latest modelling studies indicate northern polar waters could be ice-free in summers within just 5-6 years.

Professor Wieslaw Maslowski told an American Geophysical Union meeting that previous projections had underestimated the processes now driving ice loss.

Summer melting this year reduced the ice cover to 4.13 million sq km, the smallest ever extent in modern times. Remarkably, this stunning low point was not even incorporated into the model runs of Professor Maslowski and his team, which used data sets from 1979 to 2004 to constrain their future projections.

In the end, it will just melt away quite suddenly Professor Peter Wadhams “Our projection of 2013 for the removal of ice in summer is not accounting for the last two minima, in 2005 and 2007,” the researcher from the Naval Postgraduate School, Monterey, California, explained to the BBC. “So given that fact, you can argue that may be our projection of 2013 is already too conservative.”

Real world

Using supercomputers to crunch through possible future outcomes has become a standard part of climate science in recent years.

Professor Maslowski’s group, which includes co-workers at Nasa and the Institute of Oceanology, Polish Academy of Sciences (PAS), is well known for producing modelled dates that are in advance of other teams.

Of all the devotees to the left’s fervent cult-like religious belief in man-made climate change, perhaps none have been more annoying, and provably wrong, than former Secretary of State John Kerry — save perhaps for the climate change cult leader himself, former Vice President Al Gore.

As a top official in former President Barack Obama’s administration, Kerry used his position and clout to further the narrative that human activity was causing devastating damage to the earth’s climate, so much so that drastic action needed to be taken, such as raising taxes and sacrificing freedom and liberty to the government, because of course, that will help save the environment.

You may even recall that Kerry’s devotion to the “science” of climate change led him to declare that it was the changing environment that was somehow inextricably linked to the civil war in Syria, the rise of the radical Islamic State group and the subsequent flood of Muslim refugees into Europe.

North Pole Soon To Be Ice Free in Summer

The Arctic Ocean in summer will very likely be ice free before 2050, at least temporarily. The efficacy of climate-protection measures will determine how often and for how long. These are the results of a new research study involving 21 research institutes from around the world, coordinated by Dirk Notz from the University of Hamburg, Germany.

The research team has analyzed recent results from 40 different climate models. Using these models, the researchers considered the future evolution of Arctic sea-ice cover in a scenario with high future CO2 emissions and little climate protection. As expected, Arctic sea ice disappeared quickly in summer in these simulations. However, the new study finds that Arctic summer sea ice also disappears occasionally if CO2 emissions are rapidly reduced.

“If we reduce global emissions rapidly and substantially, and thus keep global warming below 2 °C relative to preindustrial levels, Arctic sea ice will nevertheless likely disappear occasionally in summer even before 2050. This really surprised us,” said Dirk Notz, who leads the sea-ice research group at University of Hamburg, Germany.
