I believe that the Earth is getting warmer through both natural and man-made processes. But, the US is contributing relatively little to the man-made part per-capita compared to other nations. Regardless, I simply don't buy into the global warming hysteria. If the Earth warms 5-10 degrees, all it will mean is more pleasant winters. Florida and NYC aren't going to sink below the sea. If places like that were, we would have started to see high-profile examples of that already, as the Earth has warmed several degrees.
TL/DR: Global warming is real, but no big deal.
Oh, you mean like Miami Beach would have to raise their sewer system by twenty feet because its streets would otherwise be underwater? Yeah, already happened. Disappearing islands in the Pacific? Already happening. Melting ice passageways in Canada that can now let container ships in where fifty years ago you had to walk over the ice? Already happening.
Are you literally blind to news about this?
