All studies of such kind always preach about a near future day of doom of some kind. They predicted the same about the CO2-problems tens of years ago, and none of the problems they talked about then have occured. Of course, there are signs that tells us not everything is correct, but still they're not anywhere near what some had expected; the earth is simply extremely adaptable. It moves on and does perfectly fine (I'm not saying it doesn't have a limit tho). So I believe this to be much the same. Man has always predicted the worst kinds of scenarios to happen, but they rarely or never do. I'm not worried about this at all.
Meh... I might be TOO indifferent about these things tho
I just think we should do what's reasonable without going over our heads with doomsday scenarios all the time
