If you're referring to the 11 year sunspot cycle, what does that have to
do
with heat and radiation here on earth?

Essentially all the heat associated with this planet comes from
the sun in the form of radiation. The tiny amount comes from
stars and space radiation, and some from Earth's core nuclear
processes, but these are insignificant. So, it would seem that
it the Sun cranks up its output we will feel the effects. This is
thought to be one of the major causes of the global warming/ice
age cycles. The earth's atmospheric gasses, land mass locations
as these relate to polar ice caps, orbital changes and axis tilt
changes all are thought to make some significant contributions,
but by and large it is the solar output that drives the cycles.

Does the solar output that drives our heating correspond to the 11 year
sunspot cycle? Here's a chart showing Earth's average temperatures over the
past few years (in geologic time of course):
http://en.wikipedia.org/wiki/Global_warming I can't see an 11 year pattern
in the chart.

My question to the poster was, specifically, what do sunspots have to do
with our atmospheric heating? In other words, besides some minor radio
disruptions, does the "output" from solar flare ups increase our heating?
Does the kind of radiation coming from the sun that warms us increase with
solar flares?

If the sunspot cycle does increase our global warming our green house
ceiling will cause it to increase that much more, faster.
