Osama bin Laden's latest reason to condemn the United States has to do with climate change.
The al Qaeda leader in a new audio message published by al Jazeera, bin Laden verbally attacks the U.S. and other industrialized nations for polluting the planet.
"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 says on the tape, according to al Jazeera.
"Speaking about climate change is not a matter of intellectual luxury - the phenomenon is an actual fact," he says.
Bin Laden, who recently released an audio tape praising a Nigerian man's attempted Christmas Day bombing of a U.S. airliner, bashes the U.S. for not signing the Kyoto Protocol.
He also praises left-wing U.S. political commentator Noam Chomsky for comparing America with the mafia.
"They are the true terrorists and therefore we should refrain from dealing in the U.S. dollar and should try to get rid of this currency as early as possible," bin Laden says.
"I am certain that such actions will have grave repercussions and huge impact."
