A picture taken on November 30, 2009 and released on December 3, 2009 by Greenpeace shows US President Barack Obama on an advertisement reading “I’m Sorry, we could have stopped catastrophic climate change … we didn’t”. The posters with heads of state have been placed all over Copenhagen International Airport by the global coalition, tcktcktck.org and Greenpeace calling on world leaders to secure a fair, ambitious and binding deal at the Copenhagen Climate Summit.
