Still flawed.

After your last comment I thought I must have missed something because you said he accounted for the worst case in column A. After watching it again, I am baffled, because I certainly didn't see it. Not only that, if more than just economic consequences are possible in column A/false, then they certainly are possible under column A/true, making column A the LESS attractive option, not the more attractive one.

Besides all that, the guy leaves out at least one other possibility. We COULD do more research and make an informed decision rather than basing action on piss poor " science ." That was the option that was left out with environmental extremists pushed for a ban on DDT, claiming that it contributed to cancer and killed off bird species, despite the fact that there was no proof of either claim. Now and estimated 300 - 800 million people suffer from malaria because their governments refuse to use DDT to eradicate malaria bearing mosquitoes despite the World Health Organization lifting the ban on DDT in 2006 citing the complete lack of any evidence of any negative side effects.

So they went with column A, and we're way worse off because of it. Not you and me, because we're not poor people living in a poor country. And DDT was pretty much eradicated here long before the ban because of the use of DDT, so it doesn't affect us directly. But there are millions of families destroyed every year because of "column A."

Now we could just act blindly following the blind lead of the blind Al Gore, who still demonizes DDT and has a picture of Rachel Carlson hanging in his office, or we could make an informed decision, recognize that the polar ice cap is expanding, not contracting, pay attention to the glaring "inaccuracies" or what the rest of the world calls lies in Al Gore's film and the science that backs it (like the stupid "Hockey Stick" graph) or we could do a little more research and make a decision that is better than column A or column B.

But, since politicians are the ones making the decisions, no matter what happens, we're screwed. Hell, even if climate change is a myth and we do nothing, it will probably costs us somehow.
