When I was an undergraduate in physics, and later in engineering, we had this quaint process where we would conduct experiments and generate data, and from these results generate conclusions.
Climate science works differently. First, political types and activists write the management summary in as alarming and as headlines-grabbing terms as they can, largely without the help or concurrence of the majority of the scientists involved in the study. Then, they spend months modifying the underlying data, models, and scientific analysis to fit this management summary.
The summary of the most recent IPCC climate survey has already been released. The body of the study, with the actual facts and models and stuff, has not been released (won't be for months) and carries this warning on the last draft:
"Changes (other than
grammatical or minor editorial changes) made after acceptance by the
Working Group or the Panel shall be those necessary to ensure
consistency with the Summary for Policymakers or the Overview Chapter."
