Climate sensitivity in CMIP6 GCMs

Posted on January 5, 2020 by ...and Then There's Physics

Anyone who is aware of what’s going on in climate science should have heard that the latest generation of climate models, known as CMIP6, seem to be suggesting a somewhat higher climate sensitivity than suggested by the previous CMIP5 models. … Continue reading →

Climategate

Posted on November 15, 2019 by ...and Then There's Physics

Climategate is a topic I’ve rarely discussed on this blog. Mostly because it’s clear that it’s not possible to have a constructive discussion with those who have different views about its significance. However, since I watched the BBC show about … Continue reading →

Kooninisms

Posted on June 18, 2019 by ...and Then There's Physics

Gavin Schmidt has a Realclimate post about a recent talk given by Steve Koonin. Somewhat bizarrely, Koonin has a response to Gavin’s post that he has posted on WUWT. Given that Koonin has no climate expertise, presumably he thinks that … Continue reading →

A Harde response

Posted on October 3, 2017 by ...and Then There's Physics

Earlier this year, I wrote a post about a paper by Hermann Harde that argued that most of the rise in atmospheric CO2 was natural. If you want more details of why this suggestion is nonsense, you can read my … Continue reading →

Climate model tuning

Posted on September 5, 2017 by ...and Then There's Physics

I wrote a post about model tuning that discussed a paper that argued for more transparency in how climate models are tuned. Gavin Schmidt, and colleagues, have now published a paper that discusses the Practice and philosophy of climate model … Continue reading →

Scientists are not salespeople!

Posted on March 10, 2017 by ...and Then There's Physics

Gavin Schmidt posted a bunch of tweets in response to a post by Scott Adams (of Dilbert fame) in which he claims to illustrate how climate scientists can persuade skeptics. If you want to read Gavin’s tweets, Greg Laden has … Continue reading →

Advocacy and scientific credibility

Posted on March 4, 2017 by ...and Then There's Physics

To the surprise of few, I suspect, it appears that scientists can advocate without damaging their, or the scientific community’s, credibility. It’s reported in this paper, [d]oes Engagement in Advocacy Hurt the Credibility of Scientists? and is discussed in this … Continue reading →
