Koyoto Treaty is important. presidents should use a little preventative medecine and not let global warming be another Katrina. Scary thing is no one knows the real ramifications of global warming, only that our CO2 emmisions are incredibly higher than any natural CO2 emmisions that the world has seen in 600,000 years. Even during ice ages. …And the men who hold high places should forge the lead for our future… Koyoto Treaty is important. presidents should use a little preventative medecine and not let global warming be another Katrina.

Some of that methane is trapped in ice called hydrate. Amazingly, there is about 400 billion tons of methane trapped in permafrost hydrate, and even more amazing, an estimated 10,000 billion tons of methane under the sea! Less than 30 billion tons of methane is equivilent to doubling the CO2 in the air. Worse, as a little methane is emitted, it causes more melting, more emissions, much more melting, much more emissions...a nasty feedback loop. Mankind's emissions will be the fuse, rapidly melting permafrost will be the detonator, and melting ocean methane hydate will be the bomb. By the way, this catastrophic chain reaction has happened before (55 million years ago-PETM-250 million years ago-the Great Dying). Unfortunately, mankind's emissions is a much stronger trigger than past severe runaway global warming episodes, so the chain reaction will happen sooner, faster, and therefore will be much, much more severe.

The more i read about this topic, the more interested i become, and i admit, i had my doubts. but i just wanted to say how much i could relate to your article for my speech and thanks for the information. i am a high school sophmore and i was given the speech topic of global warming for a contest.
