"One million people is a low threshold and it risks falling prey to a 'tyranny of minorities' backed by resourceful and well-organized interest groups," he says.

...course, grappling with something as vastly complex as climate science involves plenty of uncertainties: What threshold represents a tipping point, after which changes accelerate? What are the chances of some unforeseen catastrophic event? What measures might come into play that limit CO2 emissions and thus mitigate climate change? And how do you precisely gauge the economic impact - particularly when dealing with the future...
...what shocked the researchers was that extended-access rats also showed deficits in their "reward threshold." That is, unrestricted exposure to large quantities of high-sugar, high-fat foods changed the functioning of the rats' brain circuitry, making it harder and harder for them to register pleasure - in other words, they developed a type of tolerance often seen in addiction - an effect that got progressively worse as the rats gained more weight. "It was quite profound," says study author Paul Kenny, an associate professor of neuroscience at the Scripps Research Institute. The reward-response effects seen in the fatty-food...
