This does, of course, put research scientists into a bit of a bind. Presumably, since they are the ones looking at these systems in detail, they are the "early warning system" for any catastrophic change. When they see catastrophe, what should a research scientist do? Write an op-ed piece in the Times asking for more research funding? I don't think so.
I think the correct move is to complete the fucking research. "Completion" means to come up with some really solid conclusions, and if the system is on course to do something nasty, to have a list of actionable steps to change it. Then, you advocate that list of actionable steps, citing your research as the basis for it. Presumably, you will NOT personally profit from those steps (except, perhaps, as a consultant).
Now, I can hear the objectivist/egoist hacker contingent's hackles raise - why shouldn't a research scientist profit from their research? Was not that their blood and tears and insight? Actually, I think that should be open for them - but they should call it marketing, not advocacy, and it should be clearly a matter of personal enrichment. The thing that an objectivist should focus on is the hypocrisy of a "call to action" masquerading as altruistic concern over the environment, when it is really a quite selfish concern for securing one's own funding source. It's not that I'm against securing one's own funding source, but to do it under the guise of advocacy is flat out wrong.
