Unsound Unsound:
This would be why it's now referred to as Climate Change rather than Global Warming. The effects are varied depending on where in the world, and the biggest effect seems to be more extremes and more unpredictability. A mild winter day does no more to prove the theory than a cold winter day does to disprove it.
No offense, the change from Global Warming to Climate change reminds me of 1984's chocolate ration change. When Big Brother lowered chocolate rations, they edited out any portions of former newspapers that went against this new change, and even switched it around. So instead of a lowered ration, they were celebrating a higher ration which didn't exist. So instead of Global Warming, we now have Climate Change, in which now any event can be a part of.
