Don, I appreciate your posts as well as Rodger's, I have great respect for you both. We have been at low solar activity so some cooling would be expected. Perhaps it should be cooler. It is matter of input vs output, it seems to be tipped toward less radiation being reflected back. If the Sun is responsible for 69%, what is responsible for 31%? I will concede that the Sun is a major factor, but we have not seen a great increase only subtle. By the time that happens the game would be over. My biology professors, in the 70's, thought man had altered the carbon cycles, outside of a global warming discussion. Erik It depends where you start your regression, but the last three charts from
your link show a leveling off and a decline for the last two to three years. Roy Spencer, Principal Research Scientist at the University of Alabama, when I talked to him last year did not claim a decline as does Lord Monckton but essentially no net global warming since 1998. The point is we have not had the runaway greenhouse effect projected by many in 1998. The recent leveling off and decline does correspond with the current solar minimum.
The NASA data also shows this see http://data.giss.nasa.gov/gistemp/2008/
A recent article in Physics Today estimates that the Sun could account for as much as 69% of the increase in Earth's average temperature. See:

Don, Thank you for the link to Lord Monckton's graph. May I suggest this link for a fuller view of the meaning of the good Lord's graph, and the underlying data?

Quoting "Don J. Colton" <djcolton@piol.com>:
By all global measures we have had no global warming for the last seven years. See http://icecap.us/images/uploads/monckton-global_warming_has_stopped.pdf
