Related: About this forumClimate change models predict remarkably accurate results
http://www.rawstory.com/rs/2013/03/27/climate-change-models-predict-remarkably-accurate-results/Forecasts of global temperature rises over the past 15 years have proved remarkably accurate, new analysis of scientists modelling of climate change shows.
The debate around the accuracy of climate modelling and forecasting has been especially intense recently, due to suggestions that forecasts have exaggerated the warming observed so far and therefore also the level warming that can be expected in the future. But the new research casts serious doubts on these claims, and should give a boost to confidence in scientific predictions of climate change.
The paper, published on Wednesday in the journal Nature Geoscience, explores the performance of a climate forecast based on data up to 1996 by comparing it with the actual temperatures observed since. The results show that scientists accurately predicted the warming experienced in the past decade, relative to the decade to 1996, to within a few hundredths of a degree.
The forecast, published in 1999 by Myles Allen and colleagues at Oxford University, was one of the first to combine complex computer simulations of the climate system with adjustments based on historical observations to produce both a most likely global mean warming and a range of uncertainty. It predicted that the decade ending in December 2012 would be a quarter of degree warmer than the decade ending in August 1996 and this proved almost precisely correct.

Wrong in just about every other metric that matters to human civilization and population.
