H20, yes water vapor makes up over 90% of greenhouse gaswhy dont you all ponder why that bit was left out???

ALL this greenhouse junk is a big lie,everything I've have heard about greenhouse is a comic book fantasy and the imagination of scientist.Science is a theory. Each season each year is different and allways has been since God Created the world.

Another ignorant video.Currently CO2 makes up about 0.0378% of the atmosphere, up from an estimated 0.0280% before the industrial revolution. To put this increase in perspective, suppose you were flying from Los Angeles to NY City. Traveling 0.0378% of the distance would not even get you off the runway at LAX. Anthropogenic Global Warming advocates argue that a CO2 concentration increase of 0.009% has heated the world over a half degree C.
