The scientists who produced it say that dire forecasts that a doubling of carbon dioxide from pre-industrial levels would cause rises in temperature of as much as 10c are unlikely.
Instead, the maximum increase is likely to be no more than 2.6c, they added, and the best guess 2.3c.
Writing in the journal Science, Andreas Schmittner of Oregon State University said he and colleagues studied how changes in carbon dioxide levels during the last ice age affected temperature.
This allowed them to extrapolate how today’s temperature will rise with carbon dioxide.' Read more: http://www.dailymail.co.uk/sciencetech/article-2065954/Climate-change-fears-exaggerated-say-scientists-claim-apocalyptic-predictions-unlikely.html#ixzz1ehZdLbHo
