Sigh
There’s been a rather contentious Twitter thread about RCP8.5, a concentration/forcing pathway I’ve discussed before. It started with a claim that it was “bollox” followed by a suggestion that it was mainly used for generating headlines, scaring gullible folk and … Continue reading
A little knowledge
There is apparently a paper from a couple of years ago that is currently doing the rounds and that argues that the Molar Mass Version of the Ideal Gas Law Points to a Very Low Climate Sensitivity. The suggestion is … Continue reading
New ocean heat content analysis
Update: (26/09/2019) This paper has now been retracted.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

There’s been a lengthy discussion on Twitter about RCP8.5. I think it was initiated by Roger Pielke Jr, who continues in his campaign to police the scientific community: RCP 8.5 is by far the favorite in climate impact studies (graph).I … Continue reading
Lewis and Curry, again
I should probably say something about the new Lewis & Curry paper. It’s mostly an update to their earlier paper that I’ve discussed before. Bottom line; there are reasons to be cautious. The basic formalism is that one can use … Continue reading
Galactic cosmic rays
There’s a recent Nature Communications paper by Svensmark et al. called [i]ncreased ionization supports growth of aerosols into cloud condensation nuclei. The basic idea is that cosmic rays (energetic particles typically accelerated by shock waves) can influence the growth of … Continue reading
What if global warming ends up being greater than we thought?
I recently wrote a post about the Brown & Caldeira paper which suggests that climate sensitivity may be on the high side of the range. Rather predictably, Nic Lewis has a guest post on Climate Etc in which he looks … Continue reading
