'The gradual increase in the rate of the rise of the carbon dixoide concentration is a sign that we are continuing to expand our energy use and availability, primarily in developing countries like India and China. With more than a billion people still without much access to electricity (and many more than that who would like access to more) and all the life-improving benefits that come with it, we still have a long way to go.'
Climatologist Dr. Roy Spencer: 'A 100 years ago or 200 years ago, out of every 10,000 molecules in the atmosphere only 3 out of 10,000 were carbon dioxide Now after 100 or 200 years of carbon dioxide emissions, four out of 10,000 are carbon dioxide. There is very little carbon dioxide in the atmosphere.'
'A paper published today in Atmospheric Chemistry and Physics finds that only about 3.75% [15 ppm] of the CO2 in the lower atmosphere is man-made from the burning of fossil fuels, and thus, the vast remainder of the 400 ppm atmospheric CO2 is from land-use changes and natural sources such as ocean outgassing and plant respiration.'
