Is anyone actually worried about global warming?
From what I have read, there is absolutely no conclusive proof that CO2 causes global warming. Also, even if it did, it effects the temperature at such and alarmingly small rate (.6 C since the industrial revolution!?) that worrying about it in our lifetime seems foolish. Also, as I understand it, global warming would provide a net benefit to agriculture anyway.
So seriously, what is the big deal?
Environmentalist please opine.
