The ‘hot model’ problem

Posted on June 10, 2022 by ...and Then There's Physics

Zeke Hausfather and colleagues recently wrote a Nature comment with suggestions about how to deal with what is called the ‘hot model’ problem. The issue is that some of the latest group of climate models have somewhat higher than expected … Continue reading →

The Greenhouse Effect

Posted on April 20, 2022 by ...and Then There's Physics

I’ve ended up in a rather silly discussion/debate on Twitter about the Greenhouse Effect. I realise it’s rather pointless, in that those who dispute it are very unlikely to accept its reality. However, it’s still interesting to think about how … Continue reading →

Techniques of climate denial

Posted on April 3, 2022 by ...and Then There's Physics

Steve Koonin, who I’ve written about before, had an op-ed in the Wall Street Journal a few months ago claiming that Greenland’s melting ice is no cause for climate-change panic. The article uses a graph of mass loss rate to … Continue reading →

A coupled climate-social system

Posted on February 24, 2022 by ...and Then There's Physics

I came across an interesting paper by Frances Moore and colleagues that considers [d]eterminants of emissions pathways in the coupled climate–social system. In the context of climate science, models that consider both the climate and society tend to not be … Continue reading →

An international solar geoengineering non-use agreement

Posted on January 24, 2022 by ...and Then There's Physics

I wrote about Solar Radiation Managment, or solar geoengineering, earlier this year. It’s become a rather contentious topic, with some regarding it as worth exploring, and others almost seeming to regard it as something we should avoid at all costs. … Continue reading →

Cumulative and (probably) irreversible

Posted on December 23, 2021 by ...and Then There's Physics

This post may be written more in frustration than anything else, but I’ve had some recent discussions that have made me wonder if even those who spend their time thinking/writing/commenting about climate change fully appreciate that it’s a cumulative problem … Continue reading →

Vulnerability and resilience

Posted on December 14, 2021 by ...and Then There's Physics

I’m starting to better understand why some reasonable people are often concerned about the way in which the impact of extreme weather events are sometimes framed. It’s quite well explained in this recent paper by Myanna Lahsen and Jesse Ribot … Continue reading →

No, it probably isn’t mostly due to changes in clouds!

Posted on November 27, 2021 by ...and Then There's Physics

I haven’t done a paper debunk for a while, but a reader got in touch to ask about a recent paper by Hans Rolf-Dübal and Fritz Vahrenholt, so I thought I would have a quick look. The paper is Radiative … Continue reading →

The Hack That Changed the World

Posted on November 12, 2021 by ...and Then There's Physics

After airing the movie, The Trick, the BBC has also broadcast a series of podcasts on Climategate called the Hack That Changed the World (H/T Dikran Marsupial). I’m not sure if all can listen to them, but I thought they … Continue reading →

The concept of net-zero

Posted on November 6, 2021 by ...and Then There's Physics

I’ve written about this before, but thought I might discuss it again. There seems to be a recurring narrative that the concept of net-zero is flawed. It might first have been presented in this article suggesting that the concept of … Continue reading →
