The government (specifically, the U.S. government) would never have been able to do anything anyways. China and India are much larger population wise and the growth of pollution there (all kinds) is a far larger threat than in the U.S.

It's not just CO(2) and such, it's everything. If those governments are unwilling to change, almost nothing in the U.S. is going to help global climate change.

Trump is right that there is a lot of hoax companies/persons trying to make a dime off of 'climate change'.

We've also seen scientists fiddle with data that makes them look bad.

Yes, climate change is real, but until things really start to get bad, the larger countries such as China and India that contribute far more to 'bad' pollution are not going to do anything about it.

That doesn't mean that we don't, but we have to be realistic about what we do about it.

If we regulate our environment such that companies go elsewhere, they will just pollute magnitudes more over in those environments. That doesn't help anyone.
