You're right. The reason why our planet keeps suffering from effects its because of the people who doesn't know how to take care of our Mother Earth. Well Ice Age is a bad event.
Not sure this is necessarily due to Global Warming, but I'd rather not talk about that bag of confusion. (And whether or not it actually is because of us or if it's just old natural effects happening again, like the Ice Age).
...no. (If you mean overtime from modding - XD heck no). It's more freezing cold weather changes, and just the unluckiness to fall ill from it, really. =/
