Another CMIP6 climate sensitivity constraint

Posted on January 6, 2020 by ...and Then There's Physics

I thought I would follow up yesterday’s post with one that highlights another paper that looks at CMIP6 climate sensitivity. It’s a paper by Femke Nijsse, and colleagues, and considers [a]n emergent constraint on Transient Climate Response from simulated historical … Continue reading →

New ocean heat content analysis

Posted on November 3, 2018 by ...and Then There's Physics

Update: (26/09/2019) This paper has now been retracted. The authors says Shortly after publication, arising from comments from Nicholas Lewis, we realized that our reported uncertainties were underestimated owing to our treatment of certain systematic errors as random errors. In … Continue reading →

A bit more about carbon budgets

Posted on September 27, 2017 by ...and Then There's Physics

I’ve been mostly at home today since we had a power cut at work and the site ended up being closed. So, I thought I would post a few more thoughts about the Millar et al. 1.5oC carbon budget paper. … Continue reading →

More time …. really?

Posted on September 19, 2017 by ...and Then There's Physics

A recent paper about [e]mission budgets and pathways consistent with limiting warming to 1.5 °C essentially argues that it is still possible to follow an emission pathway that will give us a good chance of keeping warming below 1.5oC. More specifically, … Continue reading →

Beyond equilibrium climate sensitivity

Posted on September 7, 2017 by ...and Then There's Physics

Since I’ve written about climate sensitivity before, and since I have a few free moments, I thought I would briefly highlight a new paper by Knutti, Rugenstein, and Hegerl called Beyond Equilibrium Climate Sensitivity. It’s really a review of a … Continue reading →

The TCR-to-ECS ratio

Posted on April 24, 2016 by ...and Then There's Physics

Something I’ve been interested in is whether or not the ratio between the Transient Climate Response (TCR) and the Equilibrium Climate Sensitivity (ECS) best estimates from most of Nic Lewis’s work makes sense. Typically his TCR best estimate is around … Continue reading →

5000 GtC

Posted on January 13, 2016 by ...and Then There's Physics

The advantage of working at a university, is that you get the opportunity to attend interesting seminars, especially if Kit Carruthers reminds you (on which note, I also discovered that Kit submitted his PhD thesis last month). The talk today … Continue reading →

Sensitivity to cumulative emissions

Posted on December 2, 2015 by ...and Then There's Physics

Something I’ve mentioned here quite regularly is the idea that warming depends roughly linearly on cumulative (total) emissions. This is slightly counter intuitive, in that warming depends logarithmically on atmospheric CO2 concentration. The reason is essentially that it incorporates climate … Continue reading →
