wow, it's easy to get you socialists' panties all up in a bunch.
As for your attack on my "unresearched" eveidence here you go kid, check out this month's Popular Science and Jebediah Reed's article about Methane's role in global warming.  "a greenhouse gas 20 times as potent as carbon dioxide, methane is being released intoe the atmosphere five times as fast as previously thought, accoring to findings from late 2006"
And as for the atmosphere having millions more parts per million CO2 during the ice age than right now, look it up in any grade school geology book.  There was much much more CO2 because there were no where near as many plants, lichen, or plankton to convert it to Oxygen.  It's really simple, or did you skip 8th grade science class when they taught CO2-O2 conversion?
Lastly, if you think that more CO2 is dumped into the atmosphere than methane than you really dont know how methane is released.  " Methane emissions have three principal sources: prodcution and transportation of coal, natural gas, and oil; anerobic decompositon of municipal wast in ladfills; and raising livestock.  smaller sources include combustion of fuossil fuels, rice culitivation, and industrial processes." -Energy Infomation Adminsitradtion Annual report on US emission of greenhouse gasses.
You really show your age and inexperience in the real world if you think your little car adds to global warming more than all of those sources combined that dump a 20x more harmful substance into the atmosphere.
Pwned, or whatever gay webspeak the kids say these days.
