CLIMATE RESEARCHERS SHOULD NOT IGNORE THE SUN

This piece looks at the work of Henrik Svensmark and his co-workers. Svensmark says: “The climate is influenced more by changes in cosmic radiation than by carbon dioxide”. CO2 has an effect, of course, “but it is far less than most current climate models assume, and also less than the influence of cosmic radiation”. In his opinion, a doubling of the greenhouse gas in the atmosphere would cause an increase in global temperature of at most one degree, and not two degrees, as is now generally accepted.
