... no such thing as "man made" global warming.... at least not in current times. But then again 40k is fiction so i'll give it to you.
haha.... i was kinda hoping for that. There is nothing quite like :headbutt: beating your head against the wall a few times. but since you asked so nicely varrius, The only question i had is someone said a political debate? I never realized that science was a political matter... (not trying to start any fires that can't be put out) but back on thread topic it seems unlikely that people capable of space flight, teraforming, and anti grav devices can't fix anything they cause. I mean it's not like there's a race that fucked uptheir worlds and race so bad that they have to float around on giant craft worlds. That would just be silly:crazy:Woog, DON'T start that debate; it never ends on forums.
Assuming the Imperium Terraformed the planets originally to make them habitable, they can probably fix any environment issues that crop up.
Edit: Oops, I forgot. ~Varrius hangs up~
