Wow it sure is nice to be back where global warming threads are debated routinely. IMO I think humans don't contribute quite as much as Gore and the liberals want you to believe. If anything, countries like China are doing the most damage anyway so why worry about it! Their unregulated pollution should be more of a worry than the USAs and Europe.
And before one of you retards brings that uneducated BS junk, I'm well experienced as a air quality engineer and am made to address the global warming issues often as it relates to future traffic.
