2025?
One of the demands from Extinction rebellion is that the [g]overnment must act now to halt biodiversity loss and reduce greenhouse gas emissions to net zero by 2025. This has been criticised as being so unrealistic as to potentially damage … Continue reading

We have 12 years
Patrick Brown has a recent blog post about whether, or not, the IPCC claims that we have 12 years to avoid catastrophic global warming. As his post highlights, there are a number of problems with this claim. Firstly, the IPCC … Continue reading
Toys, pram, out!
It seems that Roger Pielke Jr is having a bit of a rant on Twitter about an interview Michael Mann gave about the recent Congressional Hearings. He accuses Michael Mann of lying about him and also suggests that he might … Continue reading

Oh no, not again
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

Judith Curry confuses laypeople about climate models
Judith Curry has written a report for the Global Warming Policy Foundation called Climate Models for the layman. As you can imagine, the key conclusions is that climate models are not fit for the purpose of justifying political policies to … Continue reading

Sensitivity to cumulative emissions
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

Clarity of meaning
A while ago I discussed a Nature Climate Change article by Greg Hollin and Warren Pearce called Tension between scientific certainty and meaning complicates communication of IPCC reports. A number of us submitted a response, which appeared today together with … Continue reading

“very likely” versus “extremely likely”
In IPCC land “very likely” means 90% – 100% probability, while extremely likely means 95% – 100% probability. In light of that, I was wondering if anyone had any insights as to why, in Chapter 10 of the IPCC’s WGI … Continue reading

Representative Concentration Pathways
I’ve noticed a fair amount of dicussion about the Representative Concentration Pathways (RCPs) varying from they’re scientific fraud, they’re overly optimistic, to the details are being hidden so the IPCC can’t be trusted. I haven’t actually paid to much attention … Continue reading
