Gene You said " ... There are a variety of possibilities to explain the warming ..." What are they?
The increase, over the past 200 years, in burning of fossil fuel, CO2 level of atmosphere and oceans and rise in temperature are very well documented and the correlation is very high. You seem to be arguing against yourself. As per your own statement natural warming is only 0.0005 per year i.e., 0.05 degrees over 100 years. The actual increase in the past 100 years is about 0.8 degrees C, this is much more than the 0.05 degrees you mentioned. regards Bhaskar On Saturday, 22 September 2012 19:59:57 UTC+5:30, Gene wrote: > > Bhaskar: > > > > You are totally correct; I could not agree more.
