Exactly. And carbon dioxide is only present in trace amounts. A recent estimate is 380 parts per million, up from about 320 ppm 50 years ago. No one, I repeat, no one, knows how much CO2 is present due to industrial activity.
The Gorons and other socialists such as BHO talk about “greenhouse gasses” as if they were all the evil output of capitalism. In fact, greenhouse gasses are normal and essential to keep the earth warm enough for humans. One of the major greenhouse gasses is water vapor. Another is methane, which comes primarily from cows and Democrats.
The earth’s climate is very poorly understood by scientists, except of course the pseudo-scientists who think they can predict the sea level at New York City 70 years from now. Our climate experts can’t even accurately tell us where a hurricane will land in 48 hours.
Obama in the White House with the Democrat Congress would saddle the United States with economy-killing new regulations and taxes in their religious Jihad aimed at non-existent, man-made, “global warming”.
CO2 levels were much higher in the past. Flora thrived, Fauna thrived. World was a warmer, wetter place. But that was long ago, things will be getting cooler from now on, as they have been for eons. The thought that man can affect this sytem to any extent is brilliance or sheer folly.
That's not accurate. Due to the isotopic signature of fossil fuel CO2, the contribution of human activities to the total CO2 content of the atmosphere can be estimated with high accuracy. The chance in the isotopic composition of atmospheric CO2 is called the "Suess effect". The Suess effect measurement can be correlated with basic estimates of industrial emissions that coincide with the observed increase of atmospheric CO2, using ice core bubbles that predate modern measurement techniques. A third method of making this estimation involves determining natural and human fluxes to the atmosphere, and examing the total system balance. This has been done and correlates both with the emissions estimates and the Suess effect.
Our climate experts can’t even accurately tell us where a hurricane will land in 48 hours.
Climate experts don't forecast hurricanes. Meteorologists do that.
