Excellent article; I've been wanting documentation on the (constant) changes in the IPCC's forecast of 'just how bad IS it (gonna be)?'
I guess that will still go down as an exercise to the budding blogger. All I could find here was:
"IPCC predictions of temperature increases per decade relative to the 1980-1999 and 1986-2005 periods, respectively. In the fourth assessment report, the range of predicted temperature increases is 0.11 to 0.64 degrees Celsius per decade; in the fifth assessment report (2013, p. 11-52), the range is 0.10 to 0.23 degrees C per decade."
I look forward to reading your report, nb. (Or should I call you "Bud?")
One guy who could feed that project pretty well is Chip Knappenberger who covers the climate change beat for Cato.
He does a good job with both the changing IPCC reports and the discrepancies between the actual predictions in the body of the report, supported by data and research as compared to the "Executive Summary" which journalists and politicians quote.
