text: I think that the factual evidence in the core samples drilled from around the world say that the earth does have warm and cool cycles.  I also believe that it is possible that whatever is inhabiting the earth during these cycles will invariably affect them in some way, be it natural or non-natural emissions and/or by-products.\nI think that if it is "bad" or not is all relative to how you look at it.  Will the weather be worse or more extreme? Possibly.  Is the earth trying to correct any imbalances?  Possibly.  Is this good or bad?  I guess it is how it will affect each individual.
