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

Infrared absorption of atmospheric carbon dioxide

Geoff Price made me aware of a paper, by an apparently highly published physicist, that considers the infrared absorption of atmospheric carbon. It concludes that CO2 is a very weak greenhouse gas and cannot be accepted as the main driver … 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

A bit more about committed warming

On a number of occasions I’ve pointed out that our warming committment is not actually the equilibrium temperature to our current atmospheric concentration because, if we halted all emissions, atmospheric CO2 would drop as the natural sinks took up more … Continue reading

A bit more about carbon budgets

I’ve been mostly at home today since we had a power cut at work and the site ended up being closed. So, I thought I would post a few more thoughts about the Millar et al. 1.5oC carbon budget paper. … Continue reading

Assessing global warming

A couple of years ago I wrote a joint post with Roger Pielke Sr that discussed assessing anthropogenic global warming. The post basically used changes in ocean heat content to assess anthropogenic global warming. The basic idea (which is not … Continue reading
