Stop it. The whole thing is a hoax.
No one should give a crap about CO2 levels for two reasons. First, CO2 is a plant nutrient and not a pollutant and second reason is the current CO2 level of 440PPM leaves a whole lot of room for more CO2. A LOT MORE.
Don't make public policy based on a hoax.
PS: The climate is always getting a little hotter Y over Y coming out of an ice age.
Agreed
