Many in the blogosphere are howling about this article from The Australian, which I linked to yesterday. At issue is what to make of a leak from an IPCC report.
From Real Climate:
- The principle error in the latest 'exclusive' is that the writer confuses a tightening of the estimate of climate sensitivity to 2xCO2 (as discussed here) with projections of climate change in 2100. These projections obviously depend on the uncertainties in the scenarios of future technology, economic progress and population (etc.) plus uncertainties in feedbacks related to the carbon or methane cycles. Unfortunately these have not been reduced since the last assessment report (and in some cases have actually increased).
