The Americans on 29 March may quietly have set in train the process that will finally derail the climate change juggernaut. The US House Committee on Science, Space, and Technology held a hearing on Climate Science: Assumptions, Policy Implications, and the Scientific Method. Continue Reading →

This is an adopted article.
In the past few weeks, I’ve been re-examining the long-standing dispute over the discrepancy between models and observations in the tropical troposphere. My interest was prompted in part by Gavin Schmidt’s recent attack on a graphic used by John Christy in numerous presentations (see recent discussion here by Judy Curry). Schmidt made the sort of offensive allegations that he makes far too often: Continue Reading →

Magoo alerts us to this wonderful post by Tony Thomas at Quadrant Online. I elevate his comment to increase its visibility immediately and I hope to have time for further comment soon.
As Magoo says: “Finally, some serious questions being asked by some serious climate scientists at the American Physical Society in an open and public forum.” Continue Reading →

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. Continue Reading →

Judith Curry draws a radical conclusion from this radical paper. The authors claim that climate forcings from both human influence and natural variation are likely of similar magnitude, which is the first time since the IPCC was created that the climate establishment has expressed that possibility. Then they admit that telling the difference between them is difficult (the science is not settled). That’s the second time that’s been said (the first time was in an early IPCC report). Since “human influence” has become a hot-button code word for guilt, perhaps the guilt might now subside. Finally, Judith has a plea for the IPCC authors: “No more ‘unequivocals’ or ‘very likelys’ in the AR5, please.” Amazing — you must read this and share it with everyone you know or don’t know. It’s sober and persuasive evidence that a tide is turning — a belief in dangerous warming no longer holds a trump card in climate studies. Make the politicians face this new scientific reality or they’ll go on for years with their ETS and carbon taxes – h/t Barry Brill
The issue of separating natural from anthropogenically forced variability, particularly in context of the attribution of 20th century climate change, has been a topic of several previous threads at Climate Etc. The issue of natural vs anthropogenically forced climate variability/change has been a key issue of contention between the climate establishment and skeptics. There are some encouraging signs that the climate establishment is maturing in their consideration of this issue. Continue Reading →
