However, most credible science does confirm that we have already entered a period of climate change. I don't care what your feelings are towards Al Gore; personally, I feel he's shifty and would never vote for him. The fact is that nitrogen has increased in our atmosphere exponentially since the Industrial Revolution and the oceans have warmed consistently and will continue to do so and that this will have potentially catastophic consequences unless it is addressed. Most scientists, in fact, claim that we have reached a point now that there is no stopping global warming no matter what we do to try to rectify the imbalance.
There are, however, promising new studies with phytoplankton (which absorb solar energy) being conducted, but again, if we remove or alter the plankton, then it will damage other parts of the ecosystem because food for marine life will be diminished.

Well, in the case you don't think another ice age could be brought about by global warming (which would kill off most of human population) we are eventually going to have a volcano worse than krakatoa erupt, block out the sun, kill plants, kill us, etc.
Not that the human race wouldn't survive, but there'd be huge setbacks.
