So which is it? 5 from 999,995 or 5 in 100,000?.....an extra 5 molecules of CO2 in combination with 999,995 molecules of air.......simply remove 5 molecules of CO2 from every 100000 molecules of air?
Or is it really 120 in 1,000,000? More likely, is it the potential to be 1000 in 1 million PLUS excess methane that is caused by a feedback loop PLUS excess nitrogen oxides, SF6, & other GHGs plus excess infra-red energy absorbing GHG phase change water vapor, which has an accelerating warming rate controlled by increasing amounts of infra-red energy absorbing, non-phase change GHGs.
No wonder you're flustered. Your percentages are wrong because you have no science or mathematics degrees, & no science, chemistry, astronomy, physics, algebra or pre-calc for your poorly (or non-) earned hi skule DEE-plooomaa.
