The question I have is who are this breed of 'climate scientists?' Who becomes a climate scientist? Why did they choose climate scientist and not some other science? What was their work before global warming became a hot topic? Do they do any work that has been useful, outside backing up the AGW hypothesis? When did they learn to build computer models? Have their computer modelling skills proved useful in any other areas? What do other scientists think of climate science? Is climate science their main thing or are they more generalist scientists who happen to be publishing climate research? And how much of the published research is actually meta-publishing, based either on data collected elsewhere or conclusions generated elsewhere?
