This past Saturday night, the world went dark for an hour.* I missed it of course. I was busy in another kind of darkness — developing my prints of DC's cherry blossoms in my friend's makeshift darkroom. But, apparently, at 8 pm, starting in Christchurch, New Zealand and working west from Australia, Dubai, and Dublin to New York, Chicago, and finally San Francisco, people from around the globe turned off their lights for a full 60 minutes in an attempt to highlight the link between energy use and climate change. They called it "Earth Hour," and it joins the ranks of other efforts to reduce our carbon footprint, such as Earth Day and last year's Earth Live concert. Bryan Walsh, who writes the Going Green column for time.com, will join us today to talk about his op-ed, "Earth Hour '08: Does It Matter?" So tell us, did you participate in Earth Hour? How did you mark the event? Or did you miss it, like me? In either event, what difference do you think it made, and does it matter?

* No, it wasn't a total solar eclipse (cue sigh of disappointment), or a prelude to the apocalypse (cue sigh of relief).
