I toss this out for comment... and contradiction, if my sense of previous enviornmental problems and their solutions is inaccurate. It seems to me that we have resolved or improved the following: acid rain in the northeast, the ozone hole problem, and smog in LA and elsewhere. This has been done with government action and through corporate response, the latter required or not. There were no doubt skeptics, whose arguments, when valid, affected for the better the rate and caliber of changes made.
In addition, my impression is that 190 or so countries agreed that there is a problem with climate change and we should take steps to do something about it. That presumably means that scientists in many of those countries advised them to do something. If this whole enterprise has been built on fraud or panic, it surely is one of the largest incidents of fraud or mass hysteria in history, rivalling Trump's three million illegal votes story as an epic catastrophe, so grand a illusion that oil companies, who acknowledge the problem, have themselves been taken in.
John McCain seemed to have the best take on this for skeptics: if human caused climate change is real, they we should do something about it, he said. If not,most of what's proposed is probably good anyway. I am told that the Pentagon, not know for hysteria, factors climate change a it's disruptive effects into its plans.
Finally, if this is all a mistake, wonderful! Then we liberals can get on to other issues, letting our socialist tentacles run wild in other fields. (I know, tentacles can't run). But the paranoia in some sectors on the right is laughable at times. I heard Limbaugh claim a few months ago that the reason scientists speculated that water on Mars could have come from melting polar ice caps came from their desire to advance the climate change agenda. Doesn't get weirder than that.
