@Theaetetus,
I fear you may be right. I have been pondering of late the adaptability of classical democracy to the world as it may evolve in the course of this century. I am a convinced believer in global warming. Just this week hundreds of Humboldt squid, denizens of the Sea of Cortez in Mexico, began washing ashore here on Vancouver Island. Last month they created quite a furor when they began littering the beaches in San Diego. We see all sorts of species migration occuring up here.
If the "best and brightest" minds on climate change are right, the worst case scenario - that of runaway global warming - would see the earth's population reduced from the 6,700-millions we currently support to a few hundred millions, say 400-millions. 6,700 down to 400. That's a kill off of 6.3-billion people. If population growth forecasts are right it will be a couple of billion more yet.
Least and last affected will be the Western world, or the northern reaches of it. How will our institutions function under these enormous pressures? Who gets a seat in the lifeboat and who gets chucked overboard that others may live?
Your Pentagon is about to release its Quadrennial Defense Review and it's going to be an eye-opener although I fully expect it to be understated. However I think it's bound to shake up a lot of people and run the denialist community out of town at long last.
East Asia, South Asia, the Middle East, Africa, Australia, South and Central America are in for an exceptionally bad time. It'll be pretty much "Them" and "Us" and I don't think they're going to be particularly happy with US.
We don't have to heat the planet very much at all before the growing freshwater crisis transforms into a catastrophic disruption of the food supply in nations like India and China and throughout Africa and parts of South America as well as Australia. I think they're already buggered whether we like to admit it or not.
Last month Britain's environment secretary, Hilary Benn, released a government report showing the "best case scenario" for climate change in Great Britain to 2070. The report showed most of Britain is likely to receive a 2-degree Celsius temperature increase and parts of the south, including London, as much as 6-degrees. This is Britain, an island nation surrounded by oceans.
We've already concluded that an average, 2-degree Celsius increase over pre-industrial temperatures is the maximum we can possibly tolerate before triggering runaway global warming. If Britain, of all places, expects a minimum of 2-degree Celsius heating, what does that say for the rest of the world, the hot parts, the vast landlocked regions?
What troubles me is that I think it we're going to fashion a democracy and institutions that will serve our grandchildren into the second half of this century we're going to have to have a very serious and extensive discussion and debate that will progress to planning and implementation of measures for adaptation and remediation. That's going to require an enormous degree of central authority and if we don't make provision that we, the people, hold the reins and exercise that authority responsibly, then someone else will grab that power and we will very much be at their mercy.
Enough of my rant.
