The WWF sponsored Earth Hour event calls on you to shut the lights for an hour this Saturday at 8:30 pm local time. This is one of the most compelling experiments of recent times, an exercise in political will. The event will take place around the world in an effort to help stop global warming, curb sea level rise, and perhaps even prevent the shut down of global thermohaline circulation. Feel the power. Will you go darkly?
If you can convince your high school, lab, university, or research institution to outen the lights, take a before and after picture like the one above, and send it in. We’ll post it here with credit to you and your school. Hopefully a space shuttle or satellite is planning to take a picture of particpating cities, which number in the hundreds.
