350 Now! Button

350.org is an international campaign dedicated to building a movement to unite the world around solutions to the climate crisis--the solutions that science and justice demand. To tackle climate change we need to move quickly, and we need to act in unison—and 2009 will be an absolutely crucial year. This December, world leaders will meet in Copenhagen, Denmark to craft a new global treaty on cutting emissions. The problem is, the treaty currently on the table doesn't meet the severity of the climate crisis—it doesn't pass the 350 test. If an international grassroots movement holds our leaders accountable to the latest climate science, we can start the global transformation we so desperately need.
