Clear thinking needed

(external-resource, 28 Nov 2015) Global warming cannot be dealt with using today’s tools and mindsets. So create some new ones.

IN SOME ways, the climate talks that begin in Paris on November 30th will show world leaders at their best. Taking a break from pressing issues such as terrorist threats and stuttering economies, they will try to avert a crisis that will pose its gravest risks long after they have left office. It is the opposite of the myopic thinking that is often said to afflict politics. A pity, then, that politicians have set themselves an impossible task, and that they are mostly going about it in the wrong way.

That climate change is happening, that it is very largely man-made and that it is exceedingly dangerous, are all now hard to deny (though America’s leading Republican presidential candidates routinely try). This year will all but certainly be the hottest since 1880, when NASA’s records begin. If so, 2015 will break a record that was set only in 2014. Every single year so far this decade has been hotter than every single year before 1998 (see article ).
