KATOWICE, Poland (AP) — A diplomat representing Fiji at the U.N.'s annual climate talks says he expects a "helpful" outcome but also one that won't make everyone happy.

Satyendra Prasad, the South Pacific island nation's permanent representative to the U.N., said the talks in Poland were at a "critical juncture" and "from everything I have heard there should be a good, a helpful outcome."

But Prasad added the need to find "middle ground" would result in some of the 200 participating countries walking away disappointed from the talks that end Friday.

Delegates have been working for two weeks to agree on ways to limit global warming to 1.5 degrees Celsius (2.7. Fahrenheit) during this century.

Prasad told The Associated Press a consensus is within reach on rules for keeping global warming in check and progress is expected on addressing climate-related costs in developing nations.
