Come December, the world’s leaders will gather in Denmark to address what is perhaps the single most important and urgent issue of our time—climate change. There’s just 32 days left until the summit begins, and were doing everything we can to demand real results from COP15. That’s why we’re excited to be powering Hopenhagen.org, the official Web site of the Hopenhagen movement.

Here’s what you can do to TakePart in the Hopenhagen movement:

-Become a citizen of Hopenhagen by signing the petition at Hopenhagen.org

-Read the latest entries in the Voices from Hopenhagen series from environmental activists Laurie David and Ed Begley, Jr.

-Add your voice to the Repower America wall to demand clean energy solutions from global leaders.

-Spread the word to your network: Become a fan on Facebook and follow @hopenhagen on Twitter.
