Lenny-
I don't know if global warming caused my man's activities is real or imagined. I'm not a scientist either, and when I see people of science unable to reach a conclusion there certainly is no basis for me to form an opinion based upon zero involvement in the research. So, I dunno.
But the last part of your post caught my attention. While I am not a scientist, I am very logical, and this is what bothers me. The atmosphere is a closed system. It doesn't blow in from outer space. The air we have is all we've got. Over the last 150 years or so we have been burning all this coal and oil, and pumping the byproducts into the air. Power plants, factories, cars, trucks, trains, and on and on. And, the to make matters worse, we are removing the natural ecosystem (forests) that is designed to "replenish" our air.
It has to have an impact. It has to! If I close up my house, fill it full of leafy trees, and light a candle I will probably be ok. But if I take out the trees and start my lawnmower in the living room the air will get hotter and poisonous.
My brain simply will not allow me to believe that all this deforestation and burning of fossil fuels over the last 150 years has had zero impact. That is not fear, that is logic.
I have absolutely no idea how much or what kind of impact man's activities have had, I am not a scientist. But I cannot walk away from the belief that every action has a reaction, natural balance, karma, whatever. And if we continue to put this much crap in the atmosphere, the result will be a crappy atmosphere.
How's the house coming?
