China, the USA, Japan, Russia, Canada, India and Brazil refused to sign up to new Kyoto style targets or to join a new Treaty about global warming. It has left the Europeans rather isolated on this issue. Now China is to publish a Chinese translation of large amounts of peer reviewed research which questions global warming in “Climate Change reconsidered” on June 15th. The Chinese Academy of Sciences wishes to make clear it does not endorse these views. It is good to see these matters being debated.
