Is CO2 the Earth's Thermostat?

Does Man-Made C02 function as the Earth's Thermostat and is it the Driver of Climate Change? Human-Caused Climate Change is Thermodynamic Nonsense!

Is CO2 the Earth's Thermostat? Carbon dioxide has nothing to do with causing global warming. CO2 Is currently traced at 400 ppm. That is one carbon-dioxide molecule for every 2500 parts of the atmosphere. Humans contribute only a scant 16 ppm which is 4% of the total CO2 accumulated in a year. CO2 only holds heat for a few seconds and there is not enough to drive climate- it is thermodynamically impossible! Also, bear in mind, that Water Vapor is the earth's most abundant and effective Greenhouse Gas. CO2 is only 5% of the earth's GHG; Water Vapor is 95% of the earth's GHG and holds heat far longer than CO2. Lastly, CO2 will increase only after temperatures rise (eg. El Nino) and oceans degas. Conversely, CO2 levels drop as temperatures cool. In other words, CO2 levels are influenced by heat or the lack thereof and therefore do not drive climate but follow climate.
Clearly, CO2 is actually a thermometer and Not a Thermostat.
Jay Lehr, Ph.D. covers the claim that #carbondioxide is the primary driver behind our climate. In his view, this claim is Absurd. To think for a moment that #CO2 is the Thermostat of the earth and drives Climate is Absurdity on the highest order ... It is Thermodynamicaly Impossible. The Notion that Anthropogenic C02 functions as the Thermostat of the earth and is the chief driver of #ClimateChange ~ #GlobalWarming is an Utter and Complete Absurdity!!
