Do meteorologists understand climate is about physics?

Here is something to ponder . There are nearly 5 billion people on the planet today all exhaling the dreaded CO2 every second of every day . If we declare CO2 to be a pollutant , do we start executing people as polluters ? This is not so fanciful , there are people within the sainted environmental movement that would indeed advocate this . There are people that would seize the environmental issue to justify a new round of ethnic cleansing . Please don't legislate mankind back to the 18th century , please don't play into the hands of racial extremists that would advocate m exterminations of this or that ethnic group according to who captures power at what time . Hitler and Stalin and Amin were enough genocide for one century .
