CANCUN, Mexico (AP) - The disconnect between rich and poor nations on fighting global warming could be on display as 193 nations begin a two-week conference in Mexico today.
Evidence is mounting that the Earth's climate already is changing in ways that will affect both sides of the wealth divide.
Despite the absence of a general treaty, the U.N. conference hopes to clear the way to mobilize billions of dollars for developing countries. A goal is to give them green technology to help them shift from fossil fuels affecting climate change.
Eighty-five countries have made specific pledges to reduce pollution or control growth but those promises amount to far less than required to keep temperatures from rising to potentially dangerous levels.
