I think the very first question is: "Is the climate really changing?"
Here in Pittsburgh some winters are colder, some are warmer, some summers are warmer, some are cooler; some springs are wetter, some autumns are drier, but all-in-all, it's the same climate it has been during my 71-year lifetime.
To be sure, the air and waters are cleaner, but that's not climate change.

Of course it is. The Climate is and has and will ALWAYS change.
The question is this -- can PUNY HUMANS really affect it at all?
Notice, the term used to be GLOBAL WARMING. That was the term used the 90's and the early 2000's until people began to notice that the earth is actually cooling, hence, the shift in the use of phrases -- the catch-all -- CLIMATE CHANGE.
In the 1970's the buzz phrase was actually GLOBAL COOLING or the NEW ICE AGE.
