There was another thread that had a picture from the report (a cartoon) of "how much man contributes to greenhouse gases". It had industry, driving, agricultural, etc. The funny/sad part is the percentages added up to 100% (100% of greenhouse gases are manmade!!).
You and I know that what it should have said was "of the greenhouse gases that man contributes, these activites give the following percentages". But, thats not what they said and thats now what people will get from the cartoon.
Mans CO2 emissions= a softball.
Total atmospheric CO2= a large beach ball.
Add the softball to the beach ball= mans CO2 + atmospheric CO2= total CO2 (not much change).
Total CO2= 1 large beach ball
Total Atmosphere= 1 hot air balloon
Add the softball to the hot air balloon.
