UN climate talks ended in deadlock today without progress on the pressing issues of emission cuts for wealthy nations or financing for the developing ones.

The world’s top producers of greenhouse gases pledged to battle climate change today, but failed to agree on targets for reducing emissions of carbon dioxide and other pollutants.

European Commission President Jose Manuel Barroso said the G8 nations must reach agreement among themselves on climate change measures and avoid taking the approach that “I will do nothing unless you do it first,” which he called a “vicious circle".
