The most recent solar minimum occurred in 2008, and the sun began to ramp up in January 2010, with an M-class flare (a flare that is 10 times less powerful than the largest flares, labeled X-class). The sun has continued to get more active, with the next solar maximum predicted for 2013.

All the planets around the sun are warming up regardless of how parasitic we seem. Although we aren't helping matters any being as destructive as we are.
I live in North Carolina and was wearing shorts yesterday since it was close to 70 degrees in the middle of January. I'm now getting ready for us to pay for that. When winter does come here I think it will be one for the record books.
