Thom YorkeRadiohead frontman Thom Yorke is once again leading Friends of the Earth’s Big Ask Campaign. (Hey, he likes Big Ask and he cannot lie.)

The campaign calls on 17 countries and the European Union to sign on to legally binding, yearly greenhouse-gas emissions targets. More specifically, FoE is asking the E.U. to adopt a target of at least 30 percent reductions by 2020 and 90 percent by 2050. And to stop making "big ass" jokes.
