Jeff, as you can see from the responses of the believers, there seems to be only a focus on man as the big problem. Good job by the "scientists". Capitalism? Hello? If there is warming as many have suggested, it is not unusual for this planet. My big question is with the Sun. No one talks about the Sun? You know, solar flares. The history and phases of the Sun might give a clue. There is a lot of information out there, but don't look behind that curtain. Why is it warmer on Mars? The simple things really.
