The ability to explain science to a lay audience is extraordinary. It is hard, and it can be made even more difficult when talking about climate. But, as the old saw goes, a picture is worth a thousand words. So how much is a moving, interactive, and informative picture (or rather, graphic) worth?
This graphic, from Bloomberg Business and the folks at GISS, nicely explains the thinking behind the attribution of current temperature trends to anthropogenic effects.
This is certainly worth a look. It is likely worth much more.
