The truth is we will never know for sure until its either too late or nothing happens.
Its the oil cruisis of the 70s all over again, we will run out by the year 2000 - oh wait we were wrong, its the year 2007, oh wait wrong again the year 3000
Scientists cant find a direct link between humans and apes yet, only hypothesis's. Until that simple (what should be simple if its true) link can be made, I wont trust any scientists.
The only truth is this, releasing carbon emissions into the atmosphere is not a good thing, who knows what it causes - but its not a good thing.
I have always wondered how the UN signed off on the Kyoto Protocol and yet there was that report last week on how the scientists have confirmed Global warming - what is the point of a UN sponsored report when its supposedly already been confirmed because of Kyoto?
Unless Kyoto was just Europe's attempt to balance the economic playing field of the mid to late 90's with the US and Canada (since they are magically the only countries that have to do anything). Funny how that ended up hmmmm.
