The Sun is a source of light and heat for life on Earth. Our ancestors realized that their lives depended upon the Sun and they held the Sun in reverent awe. We still recognize the importance of the Sun and find the Sun to be awe inspiring. In addition we seek to understand how it works, why it changes, and how these changes influence us here on planet Earth. The Sun was much dimmer in its youth and yet the Earth was not frozen. The quantity and quality of light from the Sun varies on time scales from milli-seconds to billions of years. During recent sunspot cycles the total solar irradiance has changed by about 0.1% with the sun being brighter at sunspot maximum. Some of these variations most certainly affect our climate but in uncertain ways.

I did a project in a data analysis course trying to correlate hurricane activity to sunspot cycles. Nothing happened. However, a meteorologist I know did a similar study in which the number of tornadoes in Michigan was anticorrelated with sunspot cycles...a minimum in sunspots corresponded to a maximum in tornadoes.
This is more year-to-year than actual climate, but hopefully it was interesting.

Marie : well this takes some explaining about sunspot!
ok here what's happening right now with us see since the
sun orbits around earth it gets closer during summer time and
far away at winter because Ozone layers has thinned out so
we'd don't want global warming as such ! were they going to stop
