It does have a measurable effect on the CO2 in the atmosphere.
Isotope ratios show the new CO2 in the atmosphere is from
burning fossil fuels.

The temperature is up quite a bit the last decade.
Coincidence?

Apparently there is evidence of a connection:
http://www.giss.nasa.gov/research/news/20011206/
but it is local not global. Europe and NA chilled off but
rest of world not so much.

"A new NASA computer climate model reinforces the
long-standing theory that low solar activity could have
changed the atmospheric circulation in the Northern
Hemisphere from the 1400s to the 1700s and triggered
a "Little Ice Age" in several regions including
North America and Europe."

Most bets are off when non-linear effects are in play.

So I was wrong. Maunder Min - Little Ice Age is
not a coincidence.
