In fact, it’s instructive to remember that global recessions have usually begun suddenly and been a real surprise to most people. As I have argued in this column and with George A. Akerlof in “Animal Spirits” (Princeton 2009), such events can largely be ascribed ultimately to contagious stories of wide significance. Basically, global recessions tend to begin when newly popular narratives reduce individuals’ motivation to spend money. Psychology matters a great deal.
The study found that the Western Australia grid could be replaced by 85 percent renewable energy at a cost $124 per MWh versus $127 per MWh for a replacement conventional system. The cheaper renewable system relies on roughly 5,000 MW of wind power, 2,000 MW of solar PV combined with battery storage and molten salt solar storage. Using a distributed grid of thousands of PV installations and hundreds of wind generators reduced costs, according to the researchers. This cost reduction was due in large part to reduced need for thousands of miles of electrical poles, wires, transformers, and associated maintenance labor.
South Florida has the only coral reef in the continental United States and 80 to 90 percent of it has died or been badly harmed over the years, officials say. The causes include ocean temperatures that have dipped too low or risen too high, acidification, sewage and pollution. Several cycles of white plague disease, including one in 2014 that coincided with the dredge, have also badly hurt South Florida’s reef. White plague, a virus that bleaches and kills coral, has been destroying reefs around the world.
“A typical person is more than five times as likely to die in an extinction event as in a car crash,” says a new report.
The risk of human extinction due to climate change—or an accidental nuclear war—is much higher than that. The Stern Review, the U.K. government’s premier report on the economics of climate change, estimated a 0.1 percent risk of human extinction every year. That may sound low, but it also adds up when extrapolated to century-scale. The Global Challenges Foundation estimates a 9.5 percent chance of human extinction within the next hundred years.
And that number probably underestimates the risk of dying in any global cataclysm. The Stern Review, whose math suggests the 9.5-percent number, only calculated the danger of species-wide extinction. The Global Challenges Foundation’s report is concerned with all events that would wipe out more than 10 percent of Earth’s human population.
“We don’t expect any of the events that we describe to happen in any 10-year period. They might—but, on balance, they probably won’t,” Sebastian Farquhar, the director of the Global Priorities Project, told me. “But there’s lots of events that we think are unlikely that we still prepare for.”
