At last….. relatively good news on CC

2 10 2013

My friend Dave Kimble who has his ear to the ground and whose work I sometimes post here has sent me this by email…….

The IPCC’s AR5 final report from Working Group 1 (still called Final Draft) is available for download,
either all in one giant file of 158 MB (mine was damaged) at or as lots of files of individual chapters, see

The RCP2.6 scenario corresponds to Peak Oil, Gas and Coal that peakists would subscribe to.  For reasons that are beyond me, you will have to click on the chart to see it full size…. ipcc.predictions It shows median summer temperatures over land rising to +1.5 C by 2045, and falling very slowly after that.

However the median is only the “most likely” for the whole world, over land, in summer.
The model predicts that the most likely half of all outcomes is in the range +1.0 to +1.8 C.
And the 90% of all outcomes range is +0.2 to +2.6 C.

This of course assumes that we manage to keep producing all the fossil fuels we can, on the downslope of Hubbert’s Curve, which seems very unlikely.

So there you have it.  Only collapse can save us from catastrophic climate change.  Though of course, we might still have fired the Clathrate Gun…..
