The annual UN Climate Talks - COP24 - ended with a whimper rather than a bang in Katowice, Poland, late on Saturday 15 December after overrunning by more than 24 hours.
Sadly these talks have been characterised by dithering and disruption rather than recapturing the high level of ambition that led to the Paris Agreement on climate change three years ago. They agreed a rulebook to implement the Paris Agreement, so enough progress was made to keep things moving forward. But much more ambition will be needed very soon to limit global warming to no more than 1.5°C.
