Kennedy Graham, another Greens MP who distorts environmental facts despite his immaculate steel-grey coiffure, says in the NBR that Rodney Hide’s depiction of the Greens (‘Zombie Greens chant false science mantra’) makes selective use of facts and conclusions. He should know, he’s an expert at it—for 16 years he was one of our diplomats. Read more… »
Let us hope so
From Judith Curry comes a remark of such simple goodness I pause in admiration and slowly nod my agreement. Of course there’s hope for the IPCC!
In a learned comment on Matt Ridley’s analysis of the draft AR5 discussion of climate sensitivity, including aerosols, clouds and water vapour, Professor Curry concludes:
JC summary: The leak of the SOD was a good thing; the IPCC still has the opportunity to do a much better job, and the wider discussion in the blogosphere and even the mainstream media places pressure on the IPCC authors to consider these issues; they can’t sweep them under the rug as in previous reports.
There’s nothing difficult in that statement; it’s quite ordinary, really. So it would be easy to overlook the obstacles to making it. Like the instinct for revenge against the IPCC for making so much of a non-existent climate problem to so many for so long. Read more… »
Actually, what IS climate change, again?
From page 7 of the leaked Summary for Policymakers from the IPCC WGI Fifth Assessment Report comes this statement about CO2 “driving” climate change (emphasis added):
Natural and anthropogenic drivers cause imbalances in the Earth’s energy budget. The strongest anthropogenic drivers are changes in greenhouse gas concentrations and aerosols. These can now be quantified in more detail, but the uncertainties of the forcing associated with aerosols remain high.
Globally, CO2 is the strongest driver of climate change compared to other changes in the atmospheric composition, and changes in surface conditions. Its relative contribution has further increased since the 1980s and by far outweighs the contributions from natural drivers. CO2 concentrations and rates of increase are unprecedented in the last 800,000 years and at least 20,000 years, respectively. Other drivers also influence climate on global and particularly regional scales.
It’s a mere fragment of grit from a mountain of a report, but still curious enough because it raises the definition of the problem, and statements about climate change have no clearer meaning just because we stopped questioning it. Read more… »
I’ve been sent some emails from people connected with the IPCC review process. The First Order Draft of the WGI contribution to the IPCC Fifth Assessment Report (AR5) Climate Change 2013: The Physical Science Basis is available for Expert Review from 16 December 2011 to 10 February 2012.
The WGI Bureau invites all experts with expertise and/or publications in the specific areas covered by the WGI Report to assist in the IPCC assessment process by registering to review here.
I have to say that it’s strange that the web site for this professional organisation, which is meant to be secured by encryption certificates, isn’t set up correctly and makes Firefox think the site is being spoofed. It appears quite amateurish. Read more… »
