Dr. Ian Wilson of the University of Southern Queensland in Toowoomba, Australia has sent me a VERY interesting graph that supports the Svensmark account of solar influence on the earth's temperature. I gather that the graph comes from data in the following two references:
Hoyt, D. V.: Using the boundary conditions of sunspots as a technique for monitoring solar luminosity variations. In: K. H. Schatten & A. Arking, Hsg.: Climate impact of solar variability. Greenbelt, NASA, 1990, 44.
Hoyt, D. V. & Schatten, K. H.: The role of the sun in climate change. New York-Oxford, Oxford University Press, 1997, 61, 70, 86, 184,188,194, 214
The graph follows:
Dr Wilson comments: It shows that the amount of heating here on the Earth's surface appears to be directly dependent on the relative strength of the magnetic field on the Sun. NOTE: An assumption is being made here that strong longitudinal fields in sunspots means a strong toroidal/dipolar field for the Sun as whole. This would support the contention that the strength of the magnetic field on the Sun controls the cosmic ray flux here on Earth which in turn regulates the world's mean temperature through the amount of low level cloud formation.(For more postings from me, see GREENIE WATCH, . My Home Page. Email me (John Ray) here.)
The graph also indicates that begining in the 1950's, the mean temperature remained in a warming trend despite normal sunspot magnetic field strength.
ReplyDeleteClearly, something else must be affecting the temperature as well?
