What's going on?
People in 188 countries turned off their lights for an hour over the weekend to raise climate change awareness, a symbolic gesture known as Earth Hour. Famous landmarks including the Eiffel Tower in Paris, Buckingham Palace in London and the United Nations headquarters in New York City joined the brief blackout.
Does turning off lights for an hour help at all?
Glenn and Stu talked about Earth Hour on today's show, with Stu explaining why small gestures like driving less or getting a more fuel-efficient vehicle to combat climate change don't really do anything. If every car and every truck in America were taken off the streets tomorrow, we would only save 5 percent of global emissions.
Small steps like turning off the lights for an hour to fight climate change are meaningless, which is why environmental advocates use numbers like "cars taken off the road" or "trees planted" to make them sound better.
"Everybody loves the environment until it affects their life in any way," Stu said.
