seriously though.. the single fatal flaw in the discussion is not separating early on, the phrase "global warming" from "mans possible contribution to global warming". everyone understands the climate is changing. we're all know we come in and out of ice ages. that video fails to separate those two arguments as well.
CO2 might lag behind temperature increases by 800 years.. but that doesn't say anything about how many is affecting current temperature increases, if at all. if so, to what extent... and to what extent in the future with population growth.
