I'm not sure how much of a trend it will be, although one thing to keep in mind is that all of this could have been avoided. I don't think that many people are necessarily "anti-science," not even Trump or any of the people you're referring to. When it comes to the science of blowing things up and making war, then they're very much pro-science.
For those who are merely struggling and trying to survive living from paycheck to paycheck, they don't really have the time or the energy to worry about what the climate will be like 50-100 years from now. In a political and economic culture where the generations living today have already mortgaged the futures of their great-grandchildren, can we really say that very many people are that concerned with the future of the planet? A cornerstone of American popular culture which even liberals have supported is the idea of self-interest: "What's in it for me?" That's the question foremost on everyone's mind - even these supposed "liberals" who claim to care so much. That's the culture that we've fostered - one of greed, pride, and selfishness.
Even the liberals and tree-hugging hippies from back in the day - they sold out decades ago, and now they're complaining about the consequences? Too little, too late. So now they want support for something they care about and not getting it.
Over the long-term, I'm actually optimistic about the future of the planet. I believe that the Earth will recover and life will continue. The worst thing that might happen is humanity may perish, but the Earth is a self-correcting mechanism and life itself may continue to flourish.
