Osama bin Laden, the al-Qaeda leader, has condemned the US and other industrial economies, holding them responsible for the phenomenon of climate change.
In an audio tape obtained by Al Jazeera, bin Laden criticised George Bush, the former US president, for rejecting the Kyoto pact and condemned global corporations.
"This is a message to the whole world about those responsible for climate change and its repercussions - whether intentionally or unintentionally - and about the action we must take," bin Laden said.
"Speaking about climate change is not a matter of intellectual luxury - the phenomenon is an actual fact." Bin Laden says "all the industrial states" are to blame for climate change, "yet the majority of those states have signed the Kyoto Protocol and agreed to curb the emission of harmful gases".
