The above provides the latest evidence that the US economy is hanging by threads. Much the same goes for Europe and Japan. About half of US households cannot weather any financial emergency nor finance long term needs such as housing, healthcare or college..... and if you like graphs of nonlinear effects, then you ought to consider what happens when gasoline or food increases in price yet again and people can't afford medication or car repairs. I see little need for strident warnings when a coming failed global economy will reduce emissions dramatically, as will slashed birth rates and suicides among those being lectured to by the rich or tenured.
