One of the numerous(*) readers of this blog has posted a review of James Kunstler's The Long Emergency. Summary: we're fucked, and the solution is to hunker down, start a commune that grows its own vegetables off the grid.
A blog called Rhinocrisy comments on a lecture by Richard Heinberg, who also seems to be a long-term commentator in this space. This one is particularly sad because it lists all the lost opportunities, over the last 25 years, where we could have done some realistic preparation for the current situation. Oh well.
How to not get completely depressed: I've been hearing predictions of dooms since the 70s (back then it was overpopulation) through the 80s (Reagan: the bombs fall in five minutes) and beyond. Nothing lasts forever, so someday a doomsayer will be right, but the odds of any one particular one being on the money are small.
Also, a lot depends on the ability of the economic system to adapt, vs. the speed of any troubles. Kunstler seems to take the view that we've infrastrured ourselves into a corner -- the suburban lifestyle can't work at all without cheap gas, and as soon as we peak everything collapses in a hurry. Thus his title. Contrast that with the cheery optimism of proclaimed genius freakonmicist Steven Leavitt, that everything is peachy because the market will simply adapt to higher oil prices. This seemed to be a really perfect example of blinkered thinking -- yes the market will adapt, but how fast, and with what cost (human and otherwise)? The comments on that post contain some good discussion.
