Just want to point out that "Christians" in this context refers to some sects of Christianity in America and these beliefs are not the norm amongst Christians worldwide. Actually I hazard, not even the norm amongst Christians in the US.
It boggles my mind that these people have taken over the definition of Christianity in such an influential country. I imagine my feelings about evangelicals are roughly the same as how mainstream muslims feel about Islamic State.
A school of theological thought that is gaining traction in protestant circles is that "new earth" spoken about in the bible is in fact this earth (fixed). Fixing this earth then has important religious significance.
This is in stark contrast to those extremist sects who wish for nuclear war to bring on the apocalypse.
Regent College (BC, Canada) have a good lecture on the subject:

(The whole series is very good in my opinion)
Also, I shouldn’t single out Christianity. I just happen to know it well because it was a big part of my childhood. A lot of other religions also have a general disregard for science.
Not all evangelicals are so adamantly anti-reason, but I'd be very confident in saying most are. Evangelical Christianity in the US is lazy and cruel. The Bible is used to justify their worst impulses, while they ignore all the parts about loving your enemies, etc. It's not a demanding religion. It's easy. Their god doesn't care about charity or peace that take effort and compassion, but only that you are on His team.
