Recently, a journalist asked me in passing – which was the best COP so far, which the worst?
Honestly, I have not been a good observer of these meetings. All I know there were many and the next is #21. There was Copenhagen, sometimes labelled Hopenhagen by enthusiasts. It was COP15 and the year was 2009. Copenhagen, the last exit, it was called, the last chance for instituting a binding policy which would make “us” limit global anthropogenic (human-caused) climate change to a stable 2 deg in 2100.
