NOAA: 2012 among the 10 warmest years on record.
"Imagine this: it’s the opening ceremony of the 2014 Winter Games in
Sochi, Russia. A huge television event, watched the world over. The
American Olympians join the proud march of nations. They’re our
emissaries, our exemplars. And as the television cameras zoom in on Team
U.S.A., one of its members quietly pulls out a rainbow flag, no bigger
than a handkerchief, and holds it up. Not ostentatiously high, but just
high enough that it can’t be mistaken."
