Committed warming

There’s been a bit of a discussion on Twitter about what it would take to stabilise atmospheric concentrations, or to stabilise global average temperatures (there seemed to be some confusion as to which was being stabilised). The bottom line seems … Continue reading

The uncertainty on the mean

I wrote a quick post about Gavin Schmidt’s post comparing models to the satellite datasets. I thought Gavin’s post was very good, and explained the various issues really well. Steve McIntyre, however, is claiming that Schmidt’s histogram doesn’t refute Christy. … Continue reading

Models versus satellites

A graph that is fairly commonly promoted to – apparently – illustrate that models and observations have diverged, is one produced by John Christy which compares models to satellite/balloon data for the troposphere. Ignoring all the potential issues with this … Continue reading

“More than half” is the same as “> 50%”!

A while ago Judith Curry wrote a rather confusing post about the IPCC’s attribution statement (that more than 50% of the warming since 1950 was anthropogenic). Gavin Schmidt responded on RealClimate, and Judith Curry has been promising to respond to … Continue reading
