UN climate talks to focus on money to help poor nations cut carbon pollution

Experts calculate that curbing and coping with global warming is going to cost trillions of dollars and poor nations just don’t have it. As United Nations climate negotiations start in Azerbaijan, the chief issue is who must ante up to help them and especially how much money it will involve. The dollar amounts being negotiated are enormous. It starts at the $100 billion in financial aid that's now going to poor nations, but experts say the need is $1 trillion or more.
