Introduction.
The sun was dismissed by the IPCC as a contributor to the apparent warming of the Earth’s climate during the period from 1975 to 2000.
It seems to be accepted that the warming that occurred in the early part of the 20th Century was more likely solar induced but it is asserted that in the late 20th Century man made influences took over and forced a rise in global temperatures that would not otherwise have happened naturally. However it is notable that the highest recorded US mainland temperatures were recorded in the 1930s and not the 1990s. That interesting fact was obscured until recently when the data was investigated and the records corrected.
