Tensions Increase as Poor Nations Stage a Protest - WSJ.com: "COPENHAGEN -- Tempers flared Monday at the United Nations climate summit as poor nations staged a walkout to protest what they called inadequate aid offers from rich countries, and the U.S. and China jockeyed for position."

World leaders, including President Barack Obama, are expected to arrive in Copenhagen later this week, ostensibly to try to seal an international agreement to curb greenhouse-gas emissions and subsidize efforts by developing countries to adopt low-carbon energy technology and adapt to shifts in weather patterns or rising sea levels.

But the talk in Copenhagen is increasingly about scaled-back expectations. One possibility is a very general agreement in which developed countries promise to try to reduce their collective emissions by some amount and to provide a pot of money to help pay for a cleanup in the developing world. But such an agreement would leave the toughest questions -- how much each country would cut, and how much each would pay -- up in the air.
