Clintel report Bingo.
Clintel, a group who thinks there is no climate emergency, and whose name – rather ironically – stands for Climate Intelligence, has published an analysis of the IPCC. You can download it here, if you’d really like to read it. … Continue reading

Methane, again.
I ended up in quite an interesting Twitter discussion about methane and CO2. I got involved when someone mentioned this thread from Ken Caldeira. The point being made is that because CO2 has a long atmospheric lifetime, and because methane … Continue reading
Some more about Hansen et al.
I thought I would expand a bit on my previous post about the recent Hansen et al. paper. Something I did like is that the paper highlighted that there is no known paleoclimate analogues for the current anthropogenic forcing pathway. … Continue reading

Hansen’s 10C
A recent comment asked about James Hansen’s recent paper in which it is claimed that equilibrium global warming for today’s GHG level is 10°C. I’ve finally had a chance to look at it and I think I understand what is … Continue reading

Approximate net zero
Since I have a few free moments, I thought I would briefly highlight a paper by Jenkins et al. on [t]he Multi-Decadal Response to Net Zero CO2 Emissions and Implications for Emissions Policy. Recent IPCC reports have highlighted that limiting … 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

No, it probably isn’t mostly due to changes in clouds!
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 effect of permafrost on the ZEC
I’ve written a number of posts about warming commitments, in particular the zero emission commitment (ZEC). In other words, how much additional warming will there be after emissions get to zero. The answer is that on multi-decadal timescales [the ZEC] … Continue reading
A chat with Mallen Baker

IPCC AR6 WG1
The site has been a little quiet, but since this blog has been going long enough to have commented on the release of the IPCC AR5 WG1 report, it only seems right to comment on the release of the IPCC’s … Continue reading
