Donald Trump made his stance on global warming clear during his campaign for president. While he has back peddled on several controversial issues he seems to be determined to withdraw from any agreements concerning global warming or climate change. This will be a drastic step backwards in the efforts to help the environment.
It is never good politics for the United States to hand over its authority to a body of international law. The United States needs to look out for its own interests, especially when working with socialist countries. There is a good chance that the Climate Pact will hurt the economy, and Trump is smart enough to know that.
No, Trump will not break Climate Pact. Since he is very unpredictable I believe he will surprise us all and he will start embracing some of Hillary's ideas, including her ecology orientation. Trump will realize the serious consequences if the USA continues to pollute unchecked. He may be a Buffon, but he is not an idiot.
Trump cannot get us into or out of international treaties by himself, as much as he would like to. The rest of the government exists to ensure the power of the president has limits. The real concern should be that Trump surrounds himself with an entire administration that wants to take the U.S. out of the Paris Climate Pact, because at that point they might be able to actually get the ball moving.
