[QUOTE="BrownArmy, post: 1148413, member: 18225"] Here's the thing though, we haven't lived on this planet for a 'gazillion' years. Our planet has gone through massive CO2/temperature/climate shifts in the last 6,000,000,000+ years, obviously. Human existence on this planet (in terms of the age of the Earth) is a tiny, insignificant blip. Climate and weather are two different topics, however, ninety percent of scientists agree that human industrial activity has had an effect on our aggregate ecological system. Are tornadoes caused by global warming? Probably not. Hurricanes? We don't have enough data. Maybe (probably not). Is glacier melt at the poles caused by global warming? Maybe; there's enough data to suggest that humans have an influence, but again, we haven't been around long enough to collect enough data to draw a statistically convincing mathematical portrait. But... Having said all that, I think a more important thing to pay attention to is the fact that [B]we're polluting our air and water to such an extent that we're destroying our capacity to live on this planet[/B]. (P.S. the Earth has an approximately sixty-mile bubble of atmosphere surrounding the planet...after that there's......A BUNCH OF NOTHING, FOR A 'GAZILLION' MILES). Maybe we should listen to some of the 'chicken-littles', who are sounding the canary-in-the-coal-mine call. No matter what happens, the Earth will live on without us (for at least 2.8 billion years, until our sun goes nova and the Earth gets roasted and ultimately consumed by the dying sun). It would be nice to be able to live out another 10,000 years as a species on this planet, instead of dying in our self-imposed noxious chemical soup. [/QUOTE]
