Nick, what i find interesting about that last graph, is that it is holding somewhat steady.. if you look at the past history, there were giant up and downswings, never, through the last 600 million years, has there been a situation like on that graph... yes, it goes up and down, but the line is fairly flat for the duration of the time, vs the past history...

maybe that is what is screwing things up? maybe earth isnt going through its natural cycle like it has been the last 600 million years, as if something has been restricting it for the last 10? maybe that is increasing volcanic activity, and earthquakes, and screwy weather with massive storms?

maybe its something we are doing to keep the earth from its wild swings like it was used to? because for the last 10k years, which humans have obviously been around, its doing something that it has never (record wise) done before...

or maybe, it is what its designed to do, because we really know jack sh!t about planets, look at how much we know about our own earth...

Global Warming is nonsense, but that is just my opinion...
