Some comments on "The Manic Sun"
Recently a book by Nigel Calder with this title was published. This book partly deals with the work of the Danish meteorologists Lassen, Svensmark and Friis-Christensen.
The Danish researchers found a rather striking correlation between
the length of the solar spot cycle and the temperature on the
Northern Hemisphere (The Southern hemisphere was not considered.).
Initially no (proposed) hypothesis to explain this could be
given. (In 1990)
In the news papers it was said that "the greenhouse theory does not exist", apart from the minds of "the greenhouse lobby".
First of all, in general, I thoroughly dislike conspiracy theories. The meteo scientists who participated in the IPCC were no "Greenpeace like catastrophists" but critical scientists with high standards with respect to integrity. Just consider the way how the final text of the 1995 IPCC report was agreed upon: Representatives from Kuwait and Saudi Arabia did NOT participate in the work to word the text of the report. In the final plenary editing meeting, however, they did their utmost to reach a "zero result" (no conclusions). If there is a bias in the 1995 IPCC report it might be over-cautious.
So let us stick to the facts. The Danes have generated some extremely interesting results, which certainly deserve a closer look.
But first of all there is the question: In what way is cloud formation
stimulated by cosmic rays, and to what extent?
Later on some studies were made by meteo scientists of the KNMI (The Netherlands). They found the following:
So it seems a controverse similar to the C-T catastrophe. Asteroid or Volcanoes? May well have been both. Global warming: The Sun or greenhouse gases? Probably both!
Below some extra graphs are shown on the subject solar spots and temperatures.
The following data were used (obtained from the KNMI internet site):
And finally: An example of rubbish on solar spots ...
