A deciding factor was that I no longer know what to say to students and postdocs regarding how to navigate the CRAZINESS in the field of climate science. Research and other professional activities are professionally rewarded only if they are channeled in certain directions approved by a politicized academic establishment — funding, ease of getting your papers published, getting hired in prestigious positions, appointments to prestigious committees and boards, professional recognition, etc.
How young scientists are to navigate all this is beyond me, and it often becomes a battle of scientific integrity versus career suicide (I have worked through these issues with a number of skeptical young scientists).
Let me relate an interaction that I had with a postdoc about a month ago. She wanted to meet me, as an avid reader of my blog. She works in a field that is certainly relevant to climate science, but she doesn't identify as a climate scientist. She says she gets questioned all the time about global warming issues, and doesn't know what to say, since topics like attribution, etc. are not topics that she explores as a scientist. WOW, a scientist that knows the difference! I advised her to keep her head down and keep doing the research that she thinks interesting and important, and to stay out of the climate debate UNLESS she decides to dig in and pursue it intellectually. Personal opinions about the science and political uopinions about policies that are sort of related to your research expertise are just that – personal and political opinions. Selling such opinions as contributing to a scientific consensus is very much worse than a joke.
Curry adds that with her resignation her "fall from the ivory tower that started in 2005 is now complete." Curry continues, "At this point, the private sector seems like a more 'honest' place for a scientist working in a politicized field than universities or government labs — at least when you are your own boss."
