An iceberg is seen in the Ilulissat fjord, on Greenland's western coast, in September 2004. Citing "a frightening lack of leadership" to tackle climate change, UN chief Kofi Annan has demanded world leaders give global warming the same priority as they did to wars and to curbing the spread of weapons of mass destruction.
