Sigh

Posted on August 11, 2019 by

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

Posted on August 7, 2019 by

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

Posted on November 3, 2018 by

I wanted to just briefly mention the recent paper that [quantifies] ocean heat uptake from changes in atmospheric O2 and CO2 composition, by Resplandy et al. The interesting thing about this paper is that it uses proxies to infer the … Continue reading →

Galactic cosmic rays

Posted on December 22, 2017 by

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?

Posted on December 17, 2017 by

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 →
