Cosmic rays provide a main sources of ionization in the atmosphere and might have an effect on cloud formation and thereby,atmospheric temperature. They may have relevance to the well-known problem with the initiation of lightning, by the arrival of dense extensive air shower cores. The basic physics behind 'Climate Change' is discussed.
The study includes an examination of the 11-year cycle of cloud cover, radon, nuclear bombs and the Chernobyl disaster. Forbush decreases in the cosmic ray flux are also studied,as well a the possibility of seeing 'cigar-shaped-clouds' coming from air showers.
A brief mention will be made of the role of past very high fluxes of high energy cosmic rays, a billion years ago,and consequently lightning, in the formation of life!
This is a joint meeting with the Environmental Physics Group.
This lecture follows the Environmental Physics Group Meeting at the Institute.
