Nothing new, US has been and is the biggest CO2 polluter. Over 2/3 of the accumulated anthropogenic greenhouse gases have been emitted by the US.
That's not even remotely true. Right now, though, the U.S. stands at only around 12% of annual GHG emissions. And even if you use cumulative numbers since the 1700s (most of which is not still in the atmosphere), the U.S. still only produced something like 20% of cumulative CO2 emissions.
The current largest CO2 emitter is China, and by a very large margin, coming in at about 35% of all world CO2 emissions, or almost three times the next worst (the United States).
Per capita, of course, the U.S. is worse than China, though not be a lot. But by that metric, the U.S. goes from being the second worst all the way down to the #16 slot. Per capita, the top ten biggest CO2 emitters are all either in the Middle East or are islands or other tiny territories. Even if you ignore the tiny countries, the U.S. *barely* makes the top 10, behind Australia, Russia, Canada, and six countries in the Middle East.
