If Mars's atmosphere is 92% CO2, where's the global warming there? Venus's atmosphere is only 64% CO2.

How do you know an expert when you see one? Remember Carl Sagan, the Guru warning that we would have a nuclear winter because of the oil wells burning in Kuwait in '91?

I think the experts can't decide if it's global cooling or warming.

What is the procedure to ORDER countries to do something that is completely internal? Embargo them? Embargo Brazil and China will trade with them. Threaten them with war? Deny their sovereignty?

Only way I see is through the UN which in my opinion is dysfunctional and corrupt.

Oh by the way there is a dandy interactive map of mars at Google. You can see every pimple and pit. There are some places that look suspiciously like eroded riverbeds about 2/3rds of the way up just to the right if center.
