Global Warming.....OOPS! Two different stories, 6 years apart.

Article 1 December, 2007---Arctic summers ice-free 'by 2013'

Science reporter, BBC News, San Francisco
Arctic summer melting in 2007 set new records

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."

Here is what actually happened to the Arctic ice, as reported 6 years later

Article 2 September, 2013 Record return of Arctic ice cap as it grows by 60% in a year

* BBC reported in 2007 global warming would leave Arctic ice-free in summer by 2013

*Publication of UN climate change report suggesting global warming caused by humans pushed back to later this month

A chilly Arctic summer has left nearly a million more square miles of ocean covered with ice than at the same time last year – an increase of 60 per cent.
The rebound from 2012’s record low comes six years after the BBC reported that global warming would leave the Arctic ice-free in summer by 2013.
Instead, days before the annual autumn re-freeze is due to begin, an unbroken ice sheet more than half the size of Europe already stretches from the Canadian islands to Russia’s northern shores.

Some eminent scientists now believe the world is heading for a period of cooling that will not end until the middle of this century – a process that would expose computer forecasts of imminent catastrophic warming as dangerously misleading.
The disclosure comes 11 months after The Mail on Sunday triggered intense political and scientific debate by revealing that global warming has ‘paused’ since the beginning of 1997 – an event that the computer models used by climate experts failed to predict.
In March, this newspaper further revealed that temperatures are about to drop below the level that the models forecast with ‘90 per cent certainty’.
The pause – which has now been accepted as real by every major climate research centre – is important, because the models’ predictions of ever-increasing global temperatures have made many of the world’s economies divert billions of pounds into ‘green’ measures to counter climate change.
Those predictions now appear gravely flawed.
