This is the same gang of superstitous fools who just recently flew hundreds of people to London to discusss whether gays eternally damned ?
As for Al Gore, his rather Disneyesque view of the environment tells us more about the pitiful state of science education in the US and Britain than the real problems.
Gore was in thrall to the Kennedy faction who hate nuclear energy and join with the Republicans to "support" US farming which does vastly more harm than SUVs, and air travel put together.
Although we haven't gone beyond the tipping point, it's pretty clear that the momentum of our society is such that even banning all flights of all kinds and every car in America won't make that much diffrence simply because of the increased wealth and consumption of China, India et al will swallow that and be hungry for more.
It's going to be bad, but fortunately we're starting the process to build hard core energy like nuclear so Britain won't be as badly affected as the madder end of nations like Germany who find themselves at the "mercy" of Russia's Gazprom and the mad as mad thing Greens in their so called government.
We're going to lose some coastline, and fools with different superstitons in places like Bangladesh are going to realise that Darwin and Malthus had a point. But too late.
Ironically of course, there won't be a Florida as such for all that long, but that's not the scary thing. The problem is that the models have all sorts of "SciFi" output. It is in the nature of numerical analysis that all sorts of mad results come out, and the trick is to drop them in the bin. But to do that you have to know what a really mad result is, and we don't. We could end up with serious changes in temperature, and there's a whole pile of mechanisms which allow for outgassing of green house gases from where they may (or may not) be current sequestrated. Screw with thr numbers a bit, and turn off the part of your brain that's listened too much to the BBC, and you get a whole pile of really scary scenarios.
