As I'm sure everyone has already discovered, Google posted a rather sobering Earth Day logo today, depicting a melting iceberg. Yahoo, on the other hand, has turned its exclamation mark into a lightbulb, which is powered by the windmill "Y." Yahoo might be trying to be cute, but Google wins for impact. Millions of people will see the logo today.
In other news, the Clinton campaign has announced that it has gone completely carbon neutral, while the Bush Administration released a "fact sheet" citing its "strong environmental record."
