One way of judging how good a job the IPCC has done of modelling global climate is to compare its predictions with a much simpler model, a linear fit of past data. Looking at a webbed graph of the data and fitting by eye, the slope of the line from 1910, when current warming seems to have started, to 1990, when the first IPCC report came out, is about .12 °C/decade. That gives a better prediction of what happened after 1990 than any of the IPCC reports.

In this post we will evaluate this contrarian claim by comparing the global surface temperature projections from each of the first four IPCC reports to the subsequent observed temperature changes.  We will see what the peer-reviewed scientific literature has to say on the subject, and show that not only have the IPCC surface temperature projections been remarkably accurate, but they have also performed much better than predictions made by climate contrarians (Figure 1).

The Intergovernmental Panel on Climate Change (IPCC) Third Assessment Report (TAR) was published in 2001, following the First Assessment Report (FAR) in 1990, and the Second Assessment Report (SAR) in 1995.  Chapter 9 of the TAR discusses the report’s projections of future climate change.

It seems that this is exactly the problem that has started bedeviling climate change models. A recent issue of Nature had a very interesting article on what seems to be a wholly paradoxical feature of models used in climate science; as the models are becoming increasingly realistic, they are also becoming less accurate and predictive because of growing uncertainties. I can only imagine this to be an excruciatingly painful fact for climate modelers who seem to be facing the equivalent of the Heisenberg uncertainty principle for their field. It’s an especially worrisome time to deal with such issues since the modelers need to include their predictions in the next IPCC report on climate change which is due to be published this year.

It is possible that Scalia’s hard-right politics are linked to his literary gifts. The commanding literary critic Lionel Trilling noted in his 1965 book Beyond Culture that many of the “monumental figures of our time” have treated “liberal ideology” as “at best a matter of indifference.” Trilling cited writers like Marcel Proust, D.H. Lawrence, and W.B. Yeats. He could have added T.S. Eliot, Wallace Stevens, Ford Madox Ford, and Evelyn Waugh.
