Well said.
Lots of non-scientists and scientists a like are jumping to conclusions, as if those are the definitive answers to the questions of climate change. The fact is that we don't know or understand enough about many of the forces affecting our climate to be able to absolutely say "Yep, that's the reason." Hypothesize, test, and keep on testing....but don't ever dismiss anything 100%. That's how science works.
We could have a full-blown ice age coming any day now...but we just don't know when that will happen. It's not a question of "if", but "when".
More important than climate change, IMHO, is the toxicity which we send into our rivers, oceans, and lakes in the form of industrial byproducts, coal ash, nuclear waste, etc. Not only will those chemicals, heavy metals, and isotopes affect the local ecosystem, they will also affect the health of humans within several degrees of separation.
