Patrick Moore, the man in the video, is discredited as a scientist in my eyes. In a 2015 interview he was defending Monsanto and the use of the herbicide glyphosate (Roundup) and he said that you could drink a whole quart of it with no ill effect. The interviewer poured him a cup of the stuff and asked him to take a sip. Moore refused to and abruptly left the interview. He has also been a spokesperson for other businesses with questionable activities. His credibility is shot. Is what some or most of what he says in the video accurate? Maybe, but it is hard to trust him.
Interesting what you wrote, didn't know that about him.
But essentially, over the years, I have heard from and read so much dissenting opinion from smart people, that I have to conclude this is not anywhere cut and dried an issue.
Should we reduce pollution, yes, that seems a no brainer. But going beyond that to restrict other energy usage activities (with cost to those restrictions) is another matter.
I have had some seriously smart friends dig up the climate data themselves and read all the various papers, reports, etc. and tell me they are not convinced it's man-made. They just did it as a hobby, so they have nothing to gain either way, except figuring out the truth.
You know this climate change thing is also related to the "peak oil" issue, which is another whole can of worms.
Above and beyond it all, we must remember there are heavily monied interests involved. This is not a purely scientific and environmental /health issue.
