Mankind is too insignificant to affect the climate. We can poison our environment and kill ourselves off that way, but change the weather? No. Not hardly. Not when nature outdoes us in all aspects by a scale of hundreds or thousands to one in scale.
That's ridiculous. The amount of gas we emit each day, are you kidding? This just sounds like an excuse to keep on guzzling gas, to drive you're huge, fast cars, to live a life of excess... so that you don't have to try and change, to actually care about something other than your own interests. that's what GW deniers sound like to me.
So you're got nothing but envy based rhetoric. Gotcha.
Listen, go to wikipedia, and look for "Atmospheric Composition". Look at the sheer mass of the atmosphere. Then look at the percenage of ALL CO2 regardless of source. Then understand that we produce only .6% of that at most. The numbers are mindbogglingly small compared to the real thing. We're talking 1 part per billion is our creation. You cannot keep up with the production of nature. We just don't have the power as a species.
Now you mean to tell me that our ability to generate 0.00234% of the atmospheric composition will produce such changes to catastrophically change this planet? Shit. A good sized fart from a moderate volcano does more faster and many times a year.
Face it, the dream of green global fascism is dead. Send flowers.
