Obama Set to Prove the Maxim that If You Give Democrats an Inch, Theyll Shred the Constitution
In 1992 President George H. W. Bush signed the United Nations Framework Convention on Climate Change.
The Senate ratified that treaty as it was written at that time, as the Constitution specifies must happen for any treaty to be valid, and President Bush signed it on October 15, 1992 just a couple of weeks before he would lose to Bill Clinton (and spoiler Ross Perot).
Decades later,
President Barack Obama is seeking to use that treaty as a Trojan Horse to push his extreme environmental agenda onto an unsuspecting, and ailing, US economy, according to the New York Times.
Aware that the Democrats are likely to lose the Senate, Obama will pursue his agenda without the peoples representatives, and will knowingly set up a constitutional controversy, maybe even a crisis, for the sake of climate change.

From your post:
... to compel nations to cut their planet-warming fossil fuel emissions ...
This will get the right wing "national sovereignty" lobby very agitated. Just imagine an international organization "compelling" a sovereign nation to do something. Is it any wonder that they fear the United Nations during into a One World Government?
