In the interests of fair play and assuming the pie chart is correct, my retort to this pie chart is this:
a) Water vapor is intrinsically related to temperature, which came first the chicken or the egg?
b) How has the rate of water vapour movement into the atmosphere changed as a consequence of land clearing, polar ice cap contractions and concrete hardstand for example
c) How has this chart considered the effects of land clearing? Is the decomposition of volitile carbon 'of plant origin' or 'human origin'
d) What are the benchmarks for the lifecycle of atmospheric CO2. How much change can we tolerate? How sensitive is our atmosphere to the reported 0.28% influence from human activity?
Just a few questions from a scientist. Oh and by the way don't pressume to know how I think!
