Prepare for another ten scorching years

Temperature records will be repeatedly shattered over the next few years, say researchers behind the first rigorous look at how global climate will change during the next decade.

The prediction comes from an innovative technique that combines the approaches used by weather forecasters, who typically look a few days ahead, and climate modellers, who produce projections that run up to the end of the century. The result is a model that can project as far as 2015, filling in a long-standing gap in climate predictions.

Although average global temperatures have been relatively flat in recent years, the model says they will start rising again next year. At least half of the years between 2009 and 2015 will exceed the current warmest year on record. By 2015, global temperatures will be 0.5 °C above the average value for the last 30 years.
