I don't believe mankind is the cause of global warming. The whole solar system is heating up. Global warming is caused by the sun and its complex effects on our tiny planet. Want proof? Just go outside on a sunny day. More energy is released by the sun in a few minutes than all the cars on this planet in a year. Granted, pollution makes the air very nasty and acid rain causes problems with crops.
But Al Gore is out to lunch on the causes of global warming. Take a peek at my FR page for more information.
Sorry about the "nuch" . . . Meant to type "Much."
