Subject: 	Sun-Climate Connection Seminar

For several years, we have sponsored work at the Mount Wilson Observatory
and the Smithsonian Observatory with Bob Jastrow, Sallie Baliunas, Willie
Soon and Eric Posmentier (Long Island University) to investigate the
effect of solar irradiance variability on the earth's climate.

On Dec. 8, from 10:30am to noon, Jastrow, Baliunas and Soon will present
the latest results of their work.  They will have just attended the
session on Solar Effects on the Earth's Climate at the AGU Meeting in San
Francisco and should be right up-to-date on the latest thinking on the
subject.

Please inform and invite anyone who I have not copied who might be
interested.

Recent progress in monitoring the climate and the solar output, as well as
modeling of the physical processes involved, are leading to improved
understanding of the influence of solar variability on terrestrial climate
change.

We will present results of modeling efforts of solar total irradiance
change on timescales of decades to centuries.  Although this is the
simplest mechanism by which the sun can affect climate change, other
mechanisms have been proposed; e.g., changing spectral irradiance.  One
such possible mechanism is the interaction of the solar ultraviolet flux
with the terrestrial upper atmosphere.

We will also discuss the possible role of solar and cosmic ray charged
particles in producing terrestrial climate change on timescales of months
to years.
