Global Dimming?!? In the second half of the 20th century, the world became, quite literally, a darker place. Defying expectation and easy explanation, hundreds of instruments around the world recorded a drop in sunshine reaching the surface of Earth, as much as 10 percent from the late 1950's to the early 90's, or 2 percent to 3 percent a decade. Has anyone been following this? Heat I might do without for a while, but I've grown very fond of light.
