Climate change doesn’t work like that

Posted on November 17, 2020 by ...and Then There's Physics

A couple of years ago I wrote a post where I tried to explain why I thought climate change was a different kind of problem when compared to most of the other issues we might face today. I find it … Continue reading →

The Carbon Cycle

Posted on May 24, 2019 by ...and Then There's Physics

Robert Rohde, who is lead scientist for Berkeley Earth, has created a really nice illustration of the carbon cycle. It shows how the CO2 cycles between the different carbon reservoirs, and how our emissions have perturbed the carbon cycle so … Continue reading →

Infrared absorption of atmospheric carbon dioxide

Posted on October 21, 2017 by ...and Then There's Physics

Geoff Price made me aware of a paper, by an apparently highly published physicist, that considers the infrared absorption of atmospheric carbon. It concludes that CO2 is a very weak greenhouse gas and cannot be accepted as the main driver … 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 →

Oh no, not again

Posted on February 26, 2017 by ...and Then There's Physics

Somehow a paper arguing that the increase in atmospheric CO2 is mostly natural has managed to pass peer-review. Gavin Schmidt’s already covered it in a Realcimate post. Gavin Cawley’s paper is, in a sense, a pre-emptive response to this new … Continue reading →

Ocean CO2 uptake – part 2

Posted on November 2, 2016 by ...and Then There's Physics

This is really a continuation of my post in which I tried to lay out the basic chemical reactions associated with the uptake of by the ocean. Nick Stokes has a similar post and has a nice online calculator. What … Continue reading →

Ocean CO2 uptake

Posted on October 30, 2016 by ...and Then There's Physics

This is a post I’ve been meaning to write for some time, and is partly motivated by a discussion Drikan and I have been having on another blog. It will probably end up being two posts, with this one simply … Continue reading →

Murry Salby in London

Posted on August 10, 2016 by ...and Then There's Physics

Joshua has pointed out that Judith Curry has written a post about Murry Salby’s recent presentation in London. There was some hope that Judith might actually express some views about his ideas, but she just seems to find it interesting. … Continue reading →

Airborne fraction

Posted on April 28, 2016 by ...and Then There's Physics

Given the recent news that the rise in CO2 has greened the planet, I can see a new “skeptic” meme appearing. Essentially, I can see them arguing that both climate sensitivity is too high, and that nature will take up … Continue reading →

Mass Balance

Posted on January 26, 2016 by ...and Then There's Physics

I once again managed to get involved in a discussion on Judith Curry’s blog about the rise in atmospheric CO2. This time was slightly better than it has been in the past, as most seemed to at least agree that … Continue reading →
