Are you signed up for Earth Hour yet?

Earth Hour 2009 will occur on March 28th from 8:30-9:30pm, local time, wherever you are in the world. Mark your calendars! And although (of course) you don't have to be signed up to turn off your lights, getting yourself on the list is a good way to show just how many people are joining forces, as the folks at Earth Hour say, "to show that it's possible to take action on global warming."

Kindermusik is, of course, signed up - and I just got this exciting update:

Dear Kindermusik,

Excitement is building all over the US and around the world. Here's a quick update on what's developed this week for Earth Hour:

More cities turning out: Atlanta, Chicago, Dallas, Las Vegas, Los Angeles, Miami, Nashville, New York, San Francisco, St. Louis and the Village of Homer Glen, Illinois. We've heard rumblings from Houston and Seattle as well and would also love to get Washington, DC on board. If you're a DC resident, let Mayor Fenty know you want the city to turn out!

Help us turn out the lights on the US Capitol Dome—write to your Senators or Member of Congress.

What goes on in Vegas doesn't always stay there: Earth Hour officially launched in Sin City at a press event featuring a Panda Bear and Vegas showgirls. The Strip will indeed go dark for the full 60 minutes—the only time the lights have been dimmed except briefly in 1998 in honor of Frank Sinatra's death.

Other city news: Chicago held its official launch event last week, with Mayor Daley again pledging his support. Next up? Nashville, Los Angeles, San Francisco and Dallas!

The city of lights goes dark: Paris and 27 other French cities announced they'll take part in Earth Hour, with the Eiffel Tower and Notre Dame going dark. A total of 405 cities in 74 countries have pledged to participate—double the number of countries from last year.

And don't forget to mark your calendar...Earth Hour is March 28, 2009, at 8:30 pm. Turn out. Take action.

Thanks!

The Earth Hour Team
