Since the political climate (no pun intended) ebbs and flows with each new administration, I wouldn't alter my plans simply because of one disastrous administration. Trump & Co. will be out of the White House one day. Unfortunately, the incredulity and enmity that so many in the US feel about anthropogenic climate change will not change much in the meantime. While we all know that academia is supersaturated with applicants vying for very few jobs, there are many different paths you could take in atmospheric science. I encourage you not to give up simply because of the public's rancour against climate scientists, though I understand the frustration.
If atmospheric science is what you're passionate about, then you should pursue it. Perhaps one day you can contribute in helping to change the public's perception about the realities of climate change.
