The Guardian reports:
Fraught negotiations over a landmark review of the world’s knowledge of climate change were making slow progress on Thursday with just hours to go before early Friday’s deadline .
The negotiations are likely to go on through the night, as countries and scientists wrangle over how to assess the global threat from greenhouse gas emissions.
At stake are projections – such as those of future temperature increases, sea level rises and the frequency of extreme weather – that will inform and guide government policies around the world for years to come.
But people involved with the talks told the Guardian that progress had been patchy and slow as delegates debate the precise wording of the 50-plus page summary.
