More than 400 protesters stuck their heads in the sand on Sydney's Bondi Beach on Thursday,

The stunt was meant to mock the Australian government's reluctance to put climate change on the

agenda of this weekend's G20 summit, being held in the country.



A protest organizer pointed to the new agreement between the United States, and China, to limit their carbon emissions. "Obama's on board, Xi Jinping's on board, everyone's on board except one man," activist Pat Norman, bellowed into a megaphone.

"Tony Abbott!" the protesters shouted back.



Young adults, children, and several people in business suits dug holes on the beach and stuck their heads in

them. The ostrich is said to stick its head in the sand in a futile bid to avoid danger.



Australian Prime Minister Tony Abbott called climate change science "crap" in 2009 and said coal was "good for humanity". His government repealed a tax on greenhouse gas emissions in July, the only country to reverse action on climate change.
