So, we should _encourage_ global warming, because when it reaches
runaway, it will be like the Biblical Flood, and purge all of the
wicked people off the planet, right?

If it gets serious, global warming will cover rather more of the earth
than the biblical flood, which probably records the flooding of the
Black Sea basin when the Mediterranean broke through the Bosphorus

It's likely to purge all of the good people as well, along with most
other forms of animal life. The end-Permian mass extinction isn't the
only one that seems to have been caused by global warming.

And, given this, are you claiming that exhorting the maximum number
of people to wring their hands, gnash their teeth, rend their garments,
and submit to your dictates of who should do what when, will change
the course of the Planet's evolution?

Which way?

Try reading George Monbiot's "Heat" - ISBN 0-7139-9924-1 - which sets
out how residents of the U.K. might cut their carbon dioxide output
down to the 0.8 tons per year which might lets us hold global warming
to only 2.0C.

At the moment., U.K. residents average 9.5 tons per year (US residents
produce about 20 tons).

It looks as if air travel will have to go, but otherwise we can hang
onto a tolerably comfortable modern lifestyle.

I always liked dirigibles.

They need to find some other gas to keep them up. The pictures
of the burning Hindenberg doesn't exactly pique my interest in riding
in one

Conventional aircraft also burn when they crash. Does that stop you
flying in them?

One could design aircraft that used liquid hydrogen as avaiation fuel
- no carbon emission there, though they would dump a lot of water in
the stratosphere, where it hangs around a bit before finally hitting
the surface as rain.

Liquid hydrogen is appreciably less dense than kerosene, so you'd
probably need to go to a blended wing-body design to get enough room
for the fuel tanks, which means that such aircraft are going to take
some time to develop, but my guess would be that this is eventually
going to happen.

The longer-term alternative is to run magnetically levitated trains
through evacuated tunnels, but that's very capital intensive. Very
cheap to run, of course, once you've got the infra-structure in place,
and potentially much quicker than aircraft.
