There's a considerable amount to the issue of "Climate Change" (and yeah, still use quotes because in the final analysis, central to all of the discussion is the warming of the Earth. There MAY be localized colder temps, but without global warming, none of the deleterious effects of greenhouse gases are of any consequence.) that I don't understand.
As my mind grasps - the primary concern is not how much greenhouse gas EXISTS so much as, how much is in a part of the atmosphere that is likely to do the most damage. Ergo, it doesn't matter bupkis how much methane or water vapor or carbon dioxide gets made down here in the lowest part of the atmosphere if its increase has no effect on warming. So if cow belches and car exhaust aren't doing it, I'm not concerned. Like, at all.
I'm skeptical that this entire globe can have received the amount of damage purported in such a short time. You can draw graphs going back to the start of the Industrial Revolution, but it doesn't scale - there's several orders of magnitude of gases created within the last 70 or so years that totally erase any contribution prior to that.
Looking over the long history of the planet - it adjusts to small perturbations eventually. Even catastrophes eventually self-correct. I was amazed at both the lingering destruction of the explosion of Mt. St. Helens - and the fact that life is returning to the areas around, and the new Spirit Lake now has life - and fish - in it. Nature recovers, given time.
So pump CO2 into the air - eventually, plant life will recover it. Heat the planet - and it will cool itself. Introduce an invasive species - and there's a good chance the ecosystem will fight back.
Actually, my primary arguments about global warming aren't about whether or not it exists - it does. Whether or not it's harmful - it is. My questions are - is it anywhere near as bad as the alarmists are saying? Is there anything we can do about it that will make any difference?
And especially - how will ANYTHING we do to restrict ourselves - and thereby pay a small price - have any effect if nations like China and India get free reign to do as much damage as they can? To me, this is like the old no smoking sections on planes - as if the chain smokers in the seat behind you have no effect on the air you were breathing. It doesn't do a lick of good to make great effort to constrain our greenhouse gas creation if every effort is offset by others who pollute more and will never comply.
