how to prove WE did it? well, it might be impossible, but so is impossible to prove, let's say...sun did it, or...a vulcano did it. kheh, and here we are, or should i say there are some who claim it's not humans fault. oh please...stop living in a denial. ok, i've already said it's close to impossible to blaim anything (sun, humanity, other natural causes) so all we can do is to make logical assumptions....here i go...for past millions of years carbon stores have builded up in earths atmosphere in different forms which we call fossil fuels. when fossil fuel or almost any other thing is being burned it emmits CO2 ( so far so true?). sooo if we burn fossil fuel mass that took millions of years to store we do a VERY RADICAL move, right? on a global scale of course. as far as CO2 making/increasing the global warming effect...he who does not believe it, is ready for sanitarium,sorry.
i don't wish to judge anyone but i agree, US should sign Kyoto protocol, and about US regular citizens...again it's not your fault and i'm not blaiming anyone here but...how much does a regular car "drink" per 100km? European cars...i think i can say it's average 7-8l.
everyone say that...i'm only one person, what effect can i have...well BIG, but if we all say this...i know, i'm the same, but ...it's just how human nature is...capitalistic period. if i was any better, i wouldn't be writting this, since i'd have no computer ...but still there are things that can be changed with minor effects on our lives.
we are AIDS on the person named Earth. just like any other virus, parasite, we are primitive in compare with our host and just like other parasites (at least most of them) we are stupid enough to kill our host, and we all know what happens to the parasit then...
