In the conclusion to his «Plan B» chapter (p 228), Bob Carter writes: «It is therefore time to move away from stale «he - says - she - says» arguments about whether human carbon dioxide emissions are causing dangerous warming, and on to designing effective policies of hazard management for all climate change, based on adaptation responses that are tailored for individual countries or regions... By their very nature, strategies that can cope with the dangers and vagaries of natural climate change will readily cope with human - caused change too should it ever become manifest.»

Callendar's own calculations, giving a 2 °C temperature rise for a carbon dioxide doubling, were slated: one major criticism was that they dealt only with radiation and left out the effects of that other important way in which heat is moved around, convection, despite what Hulburt had already written about that.

You write: «And, speaking of short periods of time on which to be drawing conclusions: the anthropogenic global warming hypothesis, correlating carbon dioxide increases with temperature increases, is based on only about 23 years -1975-1998.

If you write that the atmospheric concentration of carbon dioxide is «widely accepted as being about 350 parts per million», and walk away, it doesn't do much good for me to answer that it is known with high confidence to be between 385 and 390 parts per million (in 2009, on a global annual average).
