The UN recently launched the Seal the Deal campaign, encouraging youth to sign the Climate Challenge Petition . This online, global petition will be presented to world leaders to remind them to sign off on an effective agreement at the UN Climate Change Conference in Copenhagen  in December. The petition also calls upon leaders to seal a deal to power green growth, protect our planet and build a more sustainable, prosperous global economy that will benefit all nations and all people.
There are many ways you can join in the campaign. You can start by signing the petition, of course, and getting your friends to sign too. Then learn about other youth activities coming up this year. Also in the works: Global Climate Week . This event will involve synchronized actions such as tree planting and media events in 100 cities around the world. During this week, mass rallies will deliver the Climate Challenge Petition to world leaders in selected capital cities.
Let your voice be heard - sign up and spread the word!
