Climate change: ‘It’s imperative world leaders step up’, says COP26 president

A new record has been set for the highest daily level of carbon dioxide in the atmosphere.

It raises fresh alarm about the pace of global warming six months after world leaders met in Glasgow promising to take urgent action.

The summit’s president, Alok Sharma, has been giving a progress report today and urging those world leaders to do more to honour the commitments they made. Failure, he said, would be “an act of monstrous self harm”.
