The Church Of Global Warming (Part 96,237)

clipped from www.paulmacrae.com We’ve got two processes here, described by two different verbs: driving and amplifying. Even though the planet is warming naturally (Fact #1), which would naturally tend to increase CO2 levels anyway, human-emitted CO2 is “driving” the greenhouse effect. This is an amazing feat when you consider that human-added concentrations of CO2 are only about five per cent of natural carbon emissions every year from factors like rotting vegetation, volcanoes, outgassing from the oceans, and the like. And amazing considering that 90 to 95 per cent of the greenhouse effect is produced by water vapor, not CO2. Never mind. For the Hadley Centre, five per cent of a trace gas like carbon dioxide (CO2 is only 380 parts per million in the atmosphere, to which human emissions add about 10 ppm every five years) is “driving” the greenhouse gas system. It’s unlikely, especially considering that the planet warmed about the same amount from 1850-1940, when human carbon emissions were still relatively low.
