COPENHAGEN -- The $10 billion a year proposed by rich nations to help the poor adapt to climate change is "not sufficient" and the gap between what's offered and what's needed could wreck the Copenhagen climate conference, American billionaire George Soros said Thursday. The investor-philanthropist, one in a line of international notables visiting the 192-nation meeting, told reporters he had developed a partial solution. Mr. Soros suggested shifting some International Monetary Fund resources from providing liquidity to stressed global financial systems to a new mission of financing projects in developing countries for clean energy and adapting to climate change.
