The other day I noticed Peter Gleick was "name calling" (climate deniers) on Twitter, so I approched him on the topic of how much "man made" co2 there is...after his reply I was going to use words like "arrogant" and a few others, instead I thought I would just use a calculator (see below)
Article continues below this advert:
Fraction#1 4/10,000 (this is used for the total of CO2 in the Earth's atmosphere it's about 400 parts in 1,000,000)
Fraction#2 4/100 (4% in old money, the best estimate of how much man has put into the Earth's atmosphere)
The Result shows how much Man has contributed, 1 part in 62,500.
Even if we put into the calculator man made CO2 as high as 5% [5/100] the result is still staggering it's just 1 part in 50,000.
So Peter Gleick and others, what is the fuss about!!!
How are you guys going to control NATURAL co2?
