Judy Curry, a climate expert that the ABC has so far avoided speaking with, provides a link and commentary to a series of submissions to the UK Parliament's review of the IPCC 5th assessment report. Amongst the submissions and definitely newsworthy is a piece by Nic Lewis.
On this Curry states:
A number of submissions make scientific arguments that they believe refute the IPCC’s conclusions. Of these, Nic Lewis‘ submission is a tour de force. Not surprisingly, his submission is on the topic of climate sensitivity. This is the clearest explanation I’ve seen of the problems with the IPCC’s arguments regarding climate sensitivity.
The intro and summary to Lewis'submission reads as follows:
Introduction and summary
1. The terms of reference for this inquiry ask various questions. I address the following
questions; my related conclusions are italicised.
- How robust are the conclusions in the AR5 Physical Science Basis report (AR5-WG1)?
In the central area of climate sensitivity, they are misleading. The substantial divergence
between sensitivity estimates from, on the one hand, satisfactory studies based on
instrumental observations over an extended period and, on the other hand, from flawed
studies and from computer models was not brought out.
- Does the AR5 address the reliability of climate models?
Not adequately. Shorter-term warming projections by climate models have been scaled
down by 40% in AR5, recognising that they are unrealistically high. But, inconsistently, no
reduction has been made in longer term projections.
- Do the AR5 Physical Science Basis report’s conclusions strengthen or weaken the economic case for action to prevent dangerous climate change?
indicates the climate system is less sensitive to greenhouse gases than previously thought.
