"There are a number of factors that contribute to that, including human activity. The question is, what are we going to do about it and at what cost?"
An "admiission"......lol. Yes, we have an impact, but we don't know to what extent. 10%, 1%, .0001%, etc. There are things we could do to not pollute the air as much, but what impact will that have and at what cost(as Thune said). IF we only affect 1% of the climate change, is it worth it to spend billions of dollars to reduce that percentage?
