DAVOS, Switzerland - Don't put off action on global warming just because times are lean. That's the message Al Gore, world environmental leaders, and American executives are sending to President Obama.
Worries are mounting that economic troubles are sapping momentum, in the US Congress and in other world capitals, for costly investment in clean energy and cutting carbon emissions.
"The oceans are being choked off of oxygen. They are dying as a result of this process we are seeing before our eyes the melting of the polar ice cap," Gore said at the World Economic Forum in Davos. "The assumption that we can continue on this path is an assumption that is collapsing."
