44660841 submission Submission + - Global warming forcasts prove accurate (guardian.co.uk) 1 Submitted by Layzej on Thursday March 28, 2013 @11:51PM Layzej writes: A recent Slashdot story noted a 1981 paper that predicted a rise in global mean temperatures and turned out to be surprisingly accurate — if a bit conservative. The guardian reports on a new paper that explores the performance of a forecast published in 1999. The new study 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 correct to within a few hundredths of a degree. Compared to the forecast, the early years of the new millennium were somewhat warmer than expected. More recently the temperature has matched the level forecasted very closely" This relative slowdown has caused some journalists to speculate that global warming may have stopped. This paper shows that this is not the case. The author of the paper, Myles Allen, notes: "Of course, we should expect fluctuations around the overall warming trend in global mean temperatures (and even more so in British weather!), but the success of these early forecasts suggests the basic understanding of human-induced climate change on which they were based is supported by subsequent observations."
