Arctic To Be Ice Free by 2015 ? No way..

For many years a variety of people - scientists, political figures, journalists and climate watchers like Al Gore - have told us that the Arctic will be ice free. The predictions were that it would be ice free sometime between 2013 and 2015, though serious scientists have always doubted this proposition, which is entirely based on model predictions (so-called "simulation science") versus observational data.

Here is the most recent data from the National Snow and Ice Data Centre in Boulder, Colorado. Red shows the September 2012 minimum extent. Green shows the current extent, which is also likely to be the minimum for 2015. The Arctic has gained hundreds of miles of ice over the past three years, much of which is thick, multi-year ice. Once again, models have it wrong.
