Dark enough for ya?...

(From the Houston Chronicle
[H]undreds of instruments around the world recorded a drop in sunshine reaching the surface of Earth, as much as 10 percent from the late 1950s to the early '90s, or 2 to 3 percent per decade. In some areas like Asia, the United States and Europe, the drop was even steeper. Hong Kong saw a 37 percent decrease in its sunlight.
Evidently due to pollution.
It just keeps getting better every day.
