In December, world leaders will meet in Copenhagen to discuss a global agreement on climate change as part of the United Nations’ Climate Change Convention (often referred to as COP15). The goal of the meeting is to reduce global warming emissions and ultimately chart a course that avoids the most severe impacts of climate change. The road to Copenhagen begins now, as heads of state flock to the United Nations in hopes of laying the groundwork for COP15. That's why today, with the Danish government, we're launching the YouTube COP15 channel, where you can you can raise your thoughts and questions on climate change through an initiative called "Raise Your Voice." We know that you've never been afraid to make your opinions heard on this important issue, from uploading footage of road trips to halt climate change in India to creating humorous educational videos about global warming: Now here's your chance to submit your most pressing questions about climate change to world leaders through YouTube. All approved entries will be broadcast on screens around COP15 in December and rated by viewers of the channel. The top-rated entries will be put in front of a panel of experts at an interactive debate that will be globally aired by YouTube/CNN International. Two winners will also receive a trip to Copenhagen to be present at the debate. Ramya Raghavan, Nonprofits & Activism, recently watched "Facing the Floods"
