CO2 is a greenhouse gas coz it traps heat and solar radiation in the atmosphere. Does the increased amount of CO2 in the climate affect our lifestyle? Yes- increase in temperatures, even marginal, changes the weather patterns and makes the oceans more acidic- Both these are very BAD.

We have only ONE planet so we can not afford to make mistakes which may cause irreversible harm.

Last line brother @builderofcastles even if we agree CO2 is not a pollutant we need to help stop or reverse further rise in global temperatures if we wish to save the Earth for our children.

Happy Holidays!!
