Specifically, they've refined the figure from a 90% probability that humans are responsible for global warming through their emissions of greenhouse gases to 95%.
[quote]The figure, in the IPCC's Fifth Assessment Report, which was released in Stockholm on Friday, is a 5 per cent increase from the panel's 2007 landmark report.
More than 600 scientists and researchers contributed to the fifth assessment report, which is the result of almost seven years' work by scientists and policymakers.
It is based on more than 50,000 contributions from around the world, and an exhaustive peer review process.

The majority of the modelling points to a global mean sea-level rise of between 26 and 82 centimetres by 2100.
The worst case scenario is for a sea level rise of 98cm.
The majority of climate models point to a mean temperature rise of around 2 degrees Celsius. The smallest predicted temperature rise is 0.3C and the largest rise is 4.8C.
"Many of the observed changes are unprecedented over decades to millennia," IPCC chairperson Rajendra Pachauri said.[/quote]

So do you think that we shouldn't be doing anything about global warming, or are you correct?
