Concerned Citizens against Climate Change (www.stopwarming.eu) is circulating an international appeal/petition: "Global warming threatens the future of the earth. Act now, before it is too late", which we invite you to sign. We believe that the immediacy of this threat has been grossly underestimated in the international negotiations devoted to it until now.
