Is Global Warming Invisible?

Is “global warming” invisible, or at least very, very difficult to depict, one wonders. How else to justify image-rich weekly The Economist’s decision juxtapose to an article about “climate change talks”, a picture of a smog-choked Chinese city?

Evidently they had absolutely no way to show in pictures what “climate change” and “global warming” actually look like

This goes on par with Scientific American’s inability to find 10 “pictures of a warming world “ (slides 1 and 2 are just one single “evidence”; slides 4, 5, 7 and 10 are no evidence of anything; and slide 9 may be misleading…)
