scientists ... All they are scared of is the money stopping flowing to them.
Let us imaging some recently qualified, numerate physics PhD graduate. What should he do?
(i) 10 years as a postdoc at Imperial College (which pays quite well, relatively speaking) might get you to the top of the relevant salary scale, paying maybe 36k. That is, unless you have to take a pay cut (or freeze) to stay employed at all. Career takes off? I recall IC professorial salaries in the physical sciences are typically 60-80k.
(ii) Walk out after your PhD and join some sort of investment bank(etc), start on 40k ish and earn a few bonuses. Probably not too hard to make 80k within 10 years if you try.
Hmm, there's a tricky career choice for the money hungry.
But wait! Also prepared to lie, sensationalize, and misinform, and clever enough to get away with it? Would you rather:
(a) be part of a community of scientists, who, despite various foibles, really _are_ trying to accurately model the world around us, and who constantly cross check results, assumptions, and models.
(b) invent, model, or sell complex financial instruments whose accuracy can only ever be determined once it's too late to do anything; and even then you don't really know: was it your model, or the (un)luck of the markets?
Oooh, now that's a tricky one. There's little money in science, and it's harder to get away with sharp practice. Hmm....
PS: Non-sensational climate science is in science journals. It is not the fault of scientists that the media generally only reports the sensational; nor their fault that the media reports the sensational because that is what sells.
