Cop26 climate deal will be harder than Paris accord, admits Sharma

Summit president says 2015 global emissions agreement a framework' but rules were left for future talks

Achieving a global climate deal in Glasgow in the next three weeks will be harder than signing the Paris agreement of 2015, the UK president-designate of the Cop26 talks has said.

Alok Sharma, the cabinet minister in charge of the UK-hosted talks, just over a week away, said the task would be to get nearly 200 countries to implement stringent cuts to their greenhouse gas emissions, in line with holding global temperature increases to within 1.5C of pre-industrial levels - a goal fast receding as global carbon output continues to climb.
