It's just not something a regular person can claim to understand. Nor can we directly experience it's impact. I don't know much about gravity but I sure know it's working every single day. I don't know much about medicine but I know enough people helped by it. Climate change is too abstract to have an opinion on.
I find that every few years the secular world comes up with an end times prophecy. Nowadays climate change gave way to Artificial Intelligence taking over the world and stealing all our jobs. I give it as much credence as I do to people on the right freaking out over trans people signifying the end of the West. 10% truth, 90% BS.
