No he doesn't. If our own government is going to disrespect the conclusions of our scientists and even the field of science itself then why shouldn't currently more scientifically enlightened nations reach out to them? Even if it's only a symbolic gesture, criticism from the global community is exactly the kind of message our leaders and their supporters need right now. They have to know that their ignorant and harmful decisions have real consequences, and since they apparently don't believe in or care about the consequences of climate change, you have to hit them with even more immediate effects, like poaching our scientists. Sadly, our President is so woefully and deliberately ignorant that I don't think he'd even understand or care if our scientists started leaving the country in large numbers as a result of hi actions.
