Bin Laden Blasts U.S. for Climate Change

Al-Qaida leader Osama bin Laden has called in a new audiotape for the world to boycott American goods and the U.S. dollar, blaming the United States and other industrialized countries for global warming.

In the tape, aired in part on Al-Jazeera television Friday, bin Laden warns of the dangers of climate change and says that the way to it is to bring "the wheels of the American economy" to a halt.

He says the world should "stop consuming American products" and "refrain from using the dollar," according to a transcript on Al-Jazeera's Web site.

The new message, whose authenticity could not immediately be confirmed, comes after a bin Laden tape released last week in which he endorsed a failed attempt to blow up an American airliner on Christmas Day.
