Even in the countries that have accepted it, the response is less than adequate. But yes, it's shameful where the US sits on this, and shameful that interests in the US seek to make climate change a partisan issue and spread misinformation.
In practice, the US has cut emissions more than any signer of the Paris Accords. That's very much not shameful in my book.
Can you provide some basis for this claim? It's the first time I've heard it.
We'd need a graph of carbon emissions by nation, over time. I'm sure the data is out there, but I'm not sure where...
As you can see, the US response is critically deficient.
