Mind you this was millions of years ago but it still has happened. I saw this documentray on friday about the entire history of the earth...just awesome. The earth has been literally destroyed dozens of times before but life still remains as you can see ( I hope). Anyway..global warming is not a new occurence...and it gets worse apart from the ice caps melting...there is this substance at the bottom of the ocean called methane-hydroxide. What is it?? it's methane but in a solid state. When the seabed becomes warm enough the methane hydroxide starts to sublimate (which means going from a solid directly to a gas) and rise into the atmosphere...because methane is 3 times more effeciant as a green house gas than carbon dioxide, the earth warms up alot faster...as soon as the seabed gets really warm..tons of the methane hydroxide spew out of the ocean into massive colums on water going as high as 3000 feet...and when this stuff mixes with the oxygen in the air...the colums explode and fire is shooting out of the sea 3000 feet! It sounds cool to watch but the effects are not good...the ice caps have melted already and the atmosphere turns a bright red colour. Drought ensues and oxygen starts to go down because of the loss of plant life..most animals on earth will die, but human always find a way to survive. How to correct this...DO NOT STOP PUTTING CARBION DIOXIDE INTO THE AIR!!! Everyone thinks that this is the right thing to do..but it's not. If you have no carbon dioxide = no greenhouse effect. This has happened before and the entire planet became covered with ice 3 miles thick...it's so cool to think about this but it's would not be funny if it really happened. Well...what do ya think??
