If anyone in actual science were caught doing ANY of that it would be termination time, and rightly so.
I am unsure of the argument why this is A-OK in climate science-ish when it would be grounds for termination and intellectual exile in science.
It's OK because it's being done to 'save the planet' from being destroyed by the Evil Capitalists. I seem to recall a quote about ends justifying means. I think that fully applies here.
