Carbon is accumulating in the atmosphere; this is scientifically proven to have harmful effects; the people responsible for carbon accumulating in the atmosphere as fast as it is are therefore responsible for those harmful effects. Do we all agree on that? So what's going on is, some of the people responsible for the harm perceive it to be to their advantage not to be held responsible for the harm. They are lying and/or expressing an unreasonable degree of skepticism about the science, thereby communicating to the public and the public authorities the message "It's not our fault." And it seems some among the public and the public authorities are arguing that it's a crime for the people at fault to misrepresent science and deny that global warming is their fault.
So I have a question, to blastula and to anyone else who thinks it's appropriate to prosecute people responsible for global warming for misrepresenting science and pleading "Not guilty":
Are you also in favor of prosecuting anti-nuclear-power activists? They misrepresent science too, and carbon accumulating in the atmosphere as fast as it is is their fault too.
