Could humans recreate Permian-like extinction?
Could humans intensify speed of global warming to a point where Permian like extinction might be repeated?
On Permian event bellow..
I was watching recently science channel and there there was an episode that was centered on Permian era extinction (known also as "Day when the earth nearly died"). Basic idea was that during Permian era (around 250 million years ago) there probably was a meteorite impact but not big enough to be contributed as the main factor in the extinction of over 90% of life species at the time. It is believed that the meteorite that would have caused such an event would have to be at least the size of Manhattan (NYC) while the actual size of the related meteorite would have been noticeably smaller to be attributed as a direct cause of such an event. But what was caused was that temperatures increased to a certain level which in fact released some of the methane (which is most potent green house gas known to man stored in the depths of oceans and kept there in semi frozen state thanks to the current temperature levels) which in turn further increased global temperatures. This in turn released heavy amounts of methane. It appears that the extinction lasted much longer then anyone thought (upwards of incredible 80,000 years). Afterworlds it took the planet 100,000 years to recover.

Are humans Gaia's immune system?

Question is is there a possibility that humans might create such conditions where not only their own existence is in question but that of much of life forms contained within our blue planet (like it occurred in Permian event)?
