A report in the Telegraph of a leaked IPCC report makes chilling reading. The report concludes that mean temperatures could jump by up to 5 degrees C ( or 9 degrees F) and sea levels could be up as much as 82cm ( 2ft 8ins) by the end of this century. They also place the likelihood of climate change being caused by human activities at 95%. That's up from 90% in 2007 and 66% in 2001 and just over 50% in 1995. Those are big jumps , and the implications of a 5 degree increase are actually scary.The UN Intergovernmental Panel on Climate Change also said there was a 95 per cent likelihood that global warming is caused by human activities. That was the highest assessment so far from the IPCC, which put the figure at 90 per cent in a previous report in 2007, 66 per cent in 2001, and just over 50 per cent in 1995.
The Telegraph reports that the IPCC report, the first of three in 2013 and 2014, will face intense scrutiny particularly after errors in the 2007 study, which wrongly predicted that all Himalayan glaciers could melt by 2035.
"Almost 200 governments have agreed to try to limit global warming to below 3.6F (2C) above pre-industrial times, which is seen as a threshold for dangerous changes including more droughts, extinctions, floods and rising seas that could swamp coastal regions and island nations. Temperatures have already risen by 1.4F (0.8C) since the Industrial Revolution.
The report will say there is a high risk global temperatures will rise by more than 3.6F this century. They could rise anywhere from about 1F to almost 9F, a wider range at both ends of the scale than predicted in the 2007 report.
