“A surprisingly large number of people still downplay the impact of climate change or deny that it is primarily a product of human activity. But why?“
Well, for starters, (putting aside that a gas as fractionally insignificant as co2 can trap heat in the atmosphere) the earth and atmosphere are far to large and man’s footprint on the earth far too small to affect things. Man can pollute the hell out of his immediate area but he cannot cause heat waves or ice ages.
Actually neither of us know that for a fact but I lean that way heavily.
