feedbacks, runaway, and tipping points

There’s been some discussion on Twitter about feedbacks, runaways, and tipping points. The issue is that some seem to confuse these and sometimes imply that we could cross thresholds where we’ll undergo a runaway. I thought I would briefly try … Continue reading

A bit more about clouds

A few years ago I posted a video by Andrew Dessler that was discussing whether or not Equilibrium Climate Sensitivity could be less than 3oC. The bottom line was that the best estimate for ECS is about 3oC. Given that … Continue reading

Water vapour and climate

Peter Sinclair has video interview with Andrew Dessler about water vapour and climate. The video doesn’t really say anything all that surprising. We are now reasonably sure that relative humidity remains roughly constant as we warm. This then allows us … Continue reading

Feedbacks, climate sensitivity and the limits of linear models

Since I’ve discussed climate sensitivity here quite a lot, I thought I would highlight a recent paper, by Knutti & Rugenstein, called feedbacks, climate sensitivity and the limits of linear models. It’s a very nice, and readable, summary and – … Continue reading
