Climate change and warfare: Cool heads or heated conflicts? | The Economist

The chart shows the correlation between the number of conflicts and the average temperature during most of the second half of the millennium, the period for which the data are best. Until the mid-18th century, this correlation is continuously and significantly negative (the line remains close to the 95% confidence level, suggesting there is only one chance in 20 that it is an accidental, random effect). In other words, lower temperatures mean more wars. Then, suddenly, the negative correlation vanishes. The line goes into positive territory, but not enough to be statistically meaningful. The inverted correlation between temperature and conflict has therefore disappeared.

The paramount question is what effect would, say, a G.M. bankruptcy have on the overall U.S. economy right now, as we head directly toward ever more perilous waters? As James Surowiecki writes in his Balance Sheet blog, even if "coming to G.M.'s rescue would only delay the inevitable until next summer... it might still make sense to put the twenty-five billion dollars into the company as a way of averting yet another massive trauma to the economy at a time when businesses and consumers are feeling incredibly fragile."
In the New York Times Economix blog this morning, Catherine Rampell explores the question of how many jobs would be lost in the event of a major "contraction" of the U.S. industry. She cites a study released by the Center for Automotive Research on Election Day.
The study... estimates "the economic impact -- in terms of jobs, compensation and tax revenues -- of a major contraction involving one or more of the Detroit Three automakers," under two separate scenarios. In both cases, there would be major short-term shocks to employment; depending on which scenario you use, a contraction of the Detroit Three would result in direct and indirect job losses of 2.5 million to 3 million in 2009.
That's a lot of jobs, right smack in the middle of the worst recession in modern times. I am one who has long believed that U.S. automakers deserved their comeuppance. But now is not the time to extract a Ford Expedition or Chevy Tahoe-size pound of flesh.
