Narrowing the climate sensitivity range?

There have been a couple of recent papers presenting analyses that claim to have narrowed the likely range for equilibrium climate sensitivity (ECS). One is Dessler et al. (currently a discussion paper under review) which suggests that the 500hPa tropical … Continue reading

More about Equilibrium Climate Sensitivity

It’s currently the AGU Fall Meeting and there was a session on Climate sensitivity and feedbacks. It included talks by Kate Marvel and Kyle Armour, and I noticed that the Convener, Andrew Dessler, had tweeted This leads to one of … Continue reading

Greater future global warming?

Before I go out I wanted to briefly mention a recent paper by Patrick Brown and Ken Caldeira called [g]reater future global warming inferred from Earth’s recent energy budget. Patrick Brown already has a nice blog post about this with … Continue reading

Combining different ECS estimates

I wanted to briefly highlight a new paper by Nic Lewis and Peter Grünwald called [o]bjectively combining AR5 instrumental period and paleoclimate climate sensitivity evidence. You may want, however, to be cautious of the term objective. As the title indicates, … Continue reading

Reconciling climate sensitivity estimates – part III, or IV?

I mentioned in a recent post that there was a new paper that claims to reconciles climate sensitivity estimates. The basic issue is that observationally-based climate sensitivity estimates have a range of about 1.5oC to about 3oC, while climate model … Continue reading

What does the Vostok ice core tell us?

Euan Mearns, who runs a blog called Energy Matters, had a post in 2014 about The Vostok ice core: Temperature CO2 and CH4. This post has apparently had 8000 reads, is probably one of the most read texts on the … Continue reading
