Thanks for catching that, Steven, and for the link. The Leifer quote should be just the part that says:
“Some scientists are indicating we should make plans to adapt to a 4C world. While prudent,
one wonders what portion of the living population now could adapt to such a world, and my view is that it’s just a few thousand people [seeking refuge] in the Arctic or Antarctica.”
(My emphasis.) I think McPherson (along with the AMEG folks) is the main one positing very firm very early dates to these consequences, but really, they are only off by a few decades from what others are saying. The main thing to keep in mind is that most of the time, the more we know, the sooner and harder it looks as though things are going to go south, the loss of Arctic sea ice volume being the most famous example, of course.
Jim wrote: "[owning firearms] cannot hurt"
I REALLY don't want to side track the main conversation, but I hope you know the stats on the increased likelihood of killing yourself or a loved one if you keep a gun in the house. I'm not even arguing against arming yourself, but saying "it cannot hurt" seems to be going a bit further than the evidence suggests.
On another note, I would like to join Jim's family in encourage him to write the book, e- or not!
And on yet another note, this passage from the last block quote in Jim's post above suggests to me that economist have to start thinking more outside the box:
Reduced consumption by the upper- and upper-middle-classes would reduce the currently-weak overall aggregate demand in the real economy even more. That aggregate demand drives economic activity and if it were to shrink in net, it would lead to shrinkages in incomes from employment, increases in unemployment, and consequently of overall demand even further.
We really have to come up with a different way of employing people and occupying their time than creating crap and buying crap. There are all sorts of valuable things that people do that aren't part of the formal economy but that keep things going. The middle and upper classes will presumably still need to eat.
--Intentionally moving away from low-labor industrial agriculture (which we will have to do anyway) is a clear example of something that could employ lots of people.
--Most houses and other buildings need to be refit with better insulation and re-landscaped for food production, water conservation and species preservation. Those sound like jobs that could employ a lot of people for a while at various levels of skill.
--We need to retool our transportation sector, but we can't wait till then to drastically reduce our car use. So lots of people could be employed both retrofitting our ubiquitous SUVs and minivans into Jeepnies (something between a bus and a cab) that could then employ a lot of people as drivers (an idea developed in
Plan C by Pat Murphy.
--People will still need to be educated and taken care of medically, both of which can be done in fairly low-carbon ways and both of which could employ yet more people.
--And of course a greatly accelerated build out of renewables will be employing many people.
--And of even more course, most full-time jobs can be turned into 30 or 20 hour jobs, instantly employing millions more people...
And there are many, many more approaches like that that mostly aren't even on the radar screen of most mainstream economists.
I'm just some dumba$$ typing away on my Mac. If I can come up with numerous ways around this, why can't people who spend their lives studying economics come up with even one?
The economy is something we make up. We can make it up in any number of ways. But if one's mind is stuck in rigid ideas of how things can and cannot be done--and if the economy continues to primarily serve the interests of 'investors' (and even more, the multi-millionaire CEOs and high finance crooks) rather than primarily serving the earth and society--any major change will seem impossible.
(Is SH still around? Would s/he be willing to weigh in on any of these with her/his background in economics?)
