Giving up on 1.5C?
One of the talking points of COP27 is giving up, or compromising, on the 1.5oC target. The main reason is simply that the remaining carbon budget is very small. Essentially, to stop global warming requires getting human emissions to (net) … Continue reading

Considering Catastrophe
There’s been quite a lot of recent coverage of a paper suggesting that climate endgames, such as global societal collapse or human extinction, have been dangerously unexplored. For those who recall the contentious RCP8.5 debate, this may seem a surprising … Continue reading

Scenarios
Just before the release of the IPCC’s AR6 WGIII report (Mitigation of Climate Change) Joeri Rogelj had a Carbon Brief guest post on how not to interpret the emission scenarios in the IPCC report. It might have been to try … Continue reading

Andrew Dessler had an article in Rolling Stone suggesting that [t]he first step to saving the planet is ignoring the economists. Stoat has already written about it and, as you might imagine, doesn’t seem to like it. Even if suggesting … Continue reading

An international solar geoengineering non-use agreement
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
