First off, global warning is a misnomer. Global warming ceases to exist above relative humidities of 40% or more due to the inability of greenhouse gases to overtake the energetics (encompasses fugacity, vapor pressure, chemical potentials) of the water molecules in the air with humidities greater than 40%.
In other words, global warming only happens in cold desserts. The world is not getting hotter, rather the world's temperature is reaching an equilibrium.
Refer to enumerable works published by Freeman Dyson. Furthermore, I, myself have modeled these molecular interactions using Monte-Carlo modeling, and Lennard-Jones correlative functions of chemical potential.
In regards to the arguments of why not err on the side of caution, or who cares it doesn't affect us to reduce emmisions; I ask you to consider the costs of these endeavours. It costs a lot of money to implement pollutant reduction systems on large scale industrial processes. For example, in crude-oil refining, if you were to say "No More CO2 emissions," the price of gas would increase exponential amounts, somewhere in the field of $35/gallon. So to pursue some half-baked liberal politician's crusade would just be a massive goose chase that will have only wasted our time.
I agree that people are very wasteful, and often times I find myself agreeing with Gore's scare tactics as it seems to be the only way to implement change anymore. Drive around at 330 am and look at all of the lighted-signs that had been on all night, or on the freeway look at all of the people you see driving 3000 pound+ cars, while only occupying these contraptions with their 160 pound body, thats just not efficient, in any sense of the word. People are so quick to point fingers at corporations anymore that they forget the corporations are just people, not some evil entity out to exploit the poor, labor the middle class, benefit the rich, and ---- the environment. Why are there no campaigns to get people to stop wasting so many resources? Actually there are! But they are from the energy companies themselves who cannot meet the demand of this energy hungry country.
