Thom Yorke served as DJ atop a Greenpeace U.K. float that marched through the streets of London Sunday, just one day before the Paris Climate Conference begins on November 30th. Thousands of protesters demanding that world leaders enforce stricter climate-protecting guidelines have already lined the streets of Paris, and similar marches were orchestrated Sunday in cities like Madrid, Rome and the British capital, where an estimated 50,000 people, including the Radiohead singer, gathered ahead of COP21. 

Yorke was among the artists who signed a petition to the leadership of the Paris conference asking for "an ambitious commitment to climate action, starting now, that will limit future global warming to below 2.0°C (3.6 °F) relative to pre-industrial levels," among other recommended efforts to prevent further exacerbating climate change.

"We are deeply concerned that our global economic and industrial systems are accelerating rates of extinction, desertification and soil depletion, degrading ecosystems, acidifying and littering our rivers and oceans, and resulting in a relentless rise in greenhouse gas emissions driving irreversible climate change," the petition stated. "In short, we are overwhelming the planet's life support systems."

While the terror attacks in Paris threatened to cancel many of the events surrounding the climate conference, Yorke tweeted that he would still travel to Paris on December 4th and 5th to take part in the Gateway to Paris gig. "Will be in Paris as planned on 4th & 5th December to put pressure on our glorious leaders at #COP21 -now or never!"
