Rising levels of 'frustration' at UN climate stalemate
Old divisions between rich and poor over money and ambition are again threatening to limit progress in UN climate negotiations.
Discussions between negotiators from nearly 200 countries have resumed in Germany, aiming to flesh out the rules on the Paris climate pact.
But developing countries say they are "frustrated" with the lack of leadership from the developed world.
Commitments to cut carbon are still "woefully inadequate" they said.
2018 marks a critical stage in the global climate negotiations process. By the end of this year, governments will meet in Poland to finalise the so-called "rulebook" of the Paris deal, agreed in the French capital in December 2015.
This is seen as a key test.
The rules will define the ways in which every country reports on their emissions and on their carbon-cutting actions and, importantly, how they will increase these actions in the years ahead.
