insolation, the sun changes very little during a solar cycle,
yes...a few tenths of a percent. However, in some frequency
bands, such as the far ultraviolet, energy output can very by
several percent. Do feedback effects exist which amplify these
insolation changes to cause climate shifts? Many solar
physicists believe they do.  Even more compelling is the
widespread belief that orbital variations (ala Milankovitch
cycles, etc) cause widescale climatic changes. The evidence for
this is compelling...but those cycles also only cause very
slight changes in total solar insolation themselves. Therefore,
if one accepts the "orbital wobble" explanation of past climate
shifts (many of which occurred much fast
