Global Warming USA has kicked off its latest campaign, called "I AM," to raise awareness of the dangers associated with global warming. Actors, athletes and musicians taking part include Mark Ruffalo, Serena Williams, Orlando Bloom, James Cameron, Adrian Grenier, Kyra Sedgwick, Kevin Bacon and others.

“One of the biggest risks we face with global warming is rising sea levels, which threaten our coastal cities where nearly half the American population lives,” said Global Green President and CEO Matt Petersen. “We must demand that our leaders invest in green technologies and green jobs at the local level where many of the solutions to climate change can and must be implemented.”


The organization is hoping to get people involved by submitting a photo of themselves "with a sign of the city or community they love that is threatened by global warming due to sea level rise, floods, droughts or more severe storms." All entries will be displayed on the Global Green USA site — with one lucky winner getting the chance to walk the green carpet during the organization's annual pre-Oscar Party. 


“Global Green’s I AM Campaign is tackling one of the most critical threats facing our cities and the people who live in them,” said Mark Ruffalo, who was recently honored by the organization for his fight against hydrofracking. “I AM empowers people to show why they care about their cities, and what they are doing to help fight global warming. If everyone can join together to help put a face to the American victims of these pending disasters, we can help show our leaders why they must act now.”
