In his announcement speech, Mr Trump said that he is the President of Pittsburgh, not Paris. The fact that this was widely derided (and even compared to Hitler) is why Trump won the election. There is still a significant core support in the US for a President who puts his pwn country first instead of last.
Seriously, we were going to eliminate American jobs for that?
The Paris Agreement was not going to stop Global Warming or even slow it appreciably. If all of the goals were met then the reduction in the expected rise would be around 0.02 C. That is too small to be accurately measured against weather so it amounts to a rounding error. The signatories were allowed to set their own goals and the only enforcement mechanism was "name and shame" so it's unlikely that it would even meet its goals. It also contained a Green Fund which was an huge funds transfer from the developed nations (led by the US but not including China or India) to the rest of the world in the name of environmental justice. That's why the agreement had nearly 200 signatories - most of the countries involved were promised cash for signing with no real penalties for failing to meet their goals.
Last week President Trump announced that he was pulling the US out of the Paris Agreement on Global Warming. Naturally the world erupted in hysterics. One of the ore heated reactions I saw was a letter to the editor in the Columbus Dispatch that talked about millions dying and global flooding. Nowhere was it reported that a majority of the country is skeptical about Global Warming or what the trade-offs to the agreement are. This is why Trump won the election. Within the bubble it is unanimous that the agreement was a good thing and that there could be no descent. The people inside the bubble aren't even aware of the bubble,Along with the Iran nuclear arms pact, the Paris Agreement was meant as the capstone on President Obama's foreign policy. Similarly, despite being a treaty in all but name, it was never submitted to the Senate for ratification. Since the two agreements were so important to Obama, the negotiators were willing to settle for a bad deal over no deal.
