Climate change is simply observed and has nothing to do with feelings or beliefs. Historically it changes slowly over thousands of years along driven by global warming or cooling. The problem now is it’s changing rapidly, noticeably affecting life on our planet in just decades and leaving insufficient time to adapt. What we are experiencing is more analogous to dinosaur extinction, except we still have a choice in the outcome.
There’s a good, simple page on the subject at the link below to climate.gov. It was published June 17th, 2015 (pre-Trump). It’s still up there now, but we’ll see for how long since the administration is eliminating what it doesn’t like. If they had any principles they wouldn’t need to silence scientific findings or other points of view.
