Mankind Has an Insignificant Impact on the Climate of Planet Earth

Carbon Dioxide is not a pollutant.  On the contrary it makes crops and forests grow faster.  Mapping by satellite shows that the earth has become about 6% greener overall in the past two decades, with forests expanding into arid regions.  The Amazon rain forest was the biggest gainer, with two tons of additional biomass per acre per year.  Certainly climate change does not help every region equally, but careful studies predict overall benefit, fewer storms, more rain, better crop yields, longer growing seasons, milder winters and decreasing heating costs in colder climates.  The news is certainly not bad and on balance may be rather good.

Someday the world will wake up and laugh when they finally understand that the entire pursuit of economic ruin in the name of saving the planet from increasing carbon dioxide is in fact a terrible joke.  You see it is an unarguable fact that the portion of the Earth’s greenhouse gas envelope contributed by man is barely one tenth of one per cent of the total.  Do the numbers your self.  CO2 is no more than 4% of the total (with water vapor being over 90% followed by methane and sulpher and nitrous oxides).  Of that 4% man contributes only a little over 3%.  Elementary school arithmetic says that 3% of 4% is 0.12% and for that we are sentencing the planet to a wealth of damaging economic impacts.

If greenhouse gases were responsible for increases in global temperature of recent decades then atmospheric physics shows that higher levels of our atmosphere would show greater warming than lower levels.  This was not found to be true during the 1978 to 1998 period of .3 degrees centigrade warming.

Some 900,000 years of ice core temperature records and carbon dioxide content records show that CO2 increases follow rather than lead increases in Earth temperature which is logical because the oceans are the primary source of CO2 and they hold more CO2 when cool than when warm, so warming causes the oceans to release more CO2.

While temperatures have fluctuated over the past 5000 years, today’s earth temperature is below average for the past 5000 years.
