Global Dimming: how it affects our happiness

By now you may have viewed the Global Dimming film. As the film says, there is a scientist from the UW Madison who was studying the effect of jet streams on our climate. The only problem was he had very little opportunity to study the air when there were no planes flying. Until September 11, when all the planes were grounded for three days. He found out that in general the earth warmed in those three days throughout the United States. So he concludes that in actuality we are getting less sun, due to the jet streams.
I started thinking how there is an increase in depression and seasonal affective disorder. As anyone who has ever worked in an office without a window can attest to, no sunlight can affect your mood. We also get a lot of our vitamin D from the sun. Vitamin D helps build bones and keeps us from suffering from fractures. It is also thought to possibly play a part in Alzheimer's.We know that people who live in the Northern parts of the world suffer more from seasonal affective disorder. So, less sunlight overall does affect our happiness.
