Carl Sagan didn't reckon on the ability of Red Adair and his cohorts to put those fires out so fast!

But that is not the point...Carl Sagan may not have been right, but it was still a good idea to put the fires out! And it makes little difference whether this warming is serious or minor...or whether we cause most of it or it is a natural cycle....the fact is, *WE* are making it worse, and it is a good idea to STOP a lot of our self-destructive behavior!

Where did we get this idea that we don't have to DO anything until all experts totally agree we have a problem, and we are out of resources, hungry and miserable? Does no one even consider that in our situation (Mars doesn't seem to available for emigration), it's best to err on the side of caution?
