Personally, I'm neither a denier nor an advocate. I just don't really care, as the climate is (and has been) suitable for me to work and play. There seems to be quite a bit of BS and trickery with the whole AGW thing though, so I snicker at that...like I would anyone who says pay attention to this hand and ignore the other.
I also believe that eventually (50 years? 200 years?) the dookie is going to hit he fan in regards to population and resources...not to mention political and religious upheaval mixed in. I think we are living right now in the apex of humanity. Seen the movies Soylent Green or Blade Runner?
I have a date with Death sometime before 2060. I just hope everything remains stable until then.
