In two weeks, the world is convening in Paris, France for what Powder Magazine says might be "the most important international talks in history." November 30 through December 11 the United Nations' Framework Convention on Climate Change's 21st Conference of the Parties (COP21) will try to agree on a plan to reduce greenhouse gases for the rest of the century. Porter Fox and the team at Powder want to save the snow we all love. Are you pro snow? Sign this petition.
