A report from the Intergovernmental Panel on Climate Change on global warming  has leaked online months before it was due to be published in the fall of 2013. The IPCC has confirmed  that the draft is authentic, but warns that some details could change by next September. In its present form, the report indicates that man-made greenhouse gas emissions  are behind rising global temperatures, New Scientist explains .
Alex Rawl, the climate skeptic that leaked the report, signed up to be a public reviewer of drafts in progress. Reports like this have been leaked in the past by people with a variety of agendas, Andy Revkin at the Dot Earth blog  points out. This latest spill brings up the question of how these reports are reviewed, and if they need to be closed until publication at all, an opinion other researchers have expressed  as well.
