The following U-Tube clip is taken from a Seminar that Mr. Gates gave back in 2010 if I remember it was over an hour long but this clip is the heart of it.

The purpose of this presentation is to show why CO2 must be eliminated and since its increase is a direct result of people using energy the only way to reduce CO2 is to reduce the number of people. — depopulation!

Depopulation is a word that progressives and environmentalists use as part of their plan to save the planet from humanity!  The history of this belief goes back 200 years to an economist Thomas Malthus who believed that over population was inevitable and would lead the famine and war. The reasons he thought this way were never valid but others picked up on this thought and used concerns of the environment to hijack that thought and adapt it to modern concerns on the environment. Some of the environmental agenda was real and needed to be addressed but those that thought the reason problem was too many people took over.

The work to control population goes back into the early 70’s and that work lead to UN Agenda 21 adopted by the UN in Rio de Janeiro in 1992.  Those that wanted few people couldn’t say that so they came up with sustainability as the goal. The vehicle was Carbon dioxide being put in the atmosphere by power generation.  And in the period from the 70 though the 90’s the planets temperature was increasing and these zealots convinced many that the increase was from CO2. Politicians seeing a way to line their pockets with money saw that a Carbon Tax could be used for that purpose; so they contracted with universities and others to come up with studies to show that CO2 was the cause of increasing temperatures.

Jame E. Hansen in a 1988 presentation to the US Congress showed how the world would be in serious trouble within 20 years based on his radiative transfer models.   Soon after this presentation the UN Intergovernmental panel on Climate Change (IPCC) was formed. And its purpose was to shown the damage that increased Temperatures would cause. Keep in mind it was never established to find the cause of the warming.  Money began to flow and with that came the pollution of science as to many were will to accept the money and forget the science.

Unfortunately Mother Nature had her own mind and was not following what these silly men thought! Although CO2 has a small effect on climate the many drivers are thermal flows of heat through the oceans and atmosphere of the planet from around the equator to the poles. These flows have well documented cycles and when, as in the period fro 1970 to 2000, they were in ascendance it gave these zealots the illusion that there was cause and effect.  Now that Mother nature is cooling the planet there theories are unable to explain why.  The current cooling cycle with last about 20 years to 2035 or so and then another warming period will began.
