DUBAI (Reuters) -Countries at the COP28 climate talks need to stop posturing, aim high and agree on a way to end the "fossil fuel era as we know it", U.N. climate chief Simon Stiell said on Wednesday, as tension over the future of coal, oil and gas came to the fore.

Stiell was speaking as the two-week conference approaches its midpoint, after the opening flurry of announcements and pledges has died down and attention turns to behind-the-scenes negotiations.
