Yesterday, I read a quick note by @michaelemann.bsky.social on the problems of UNFCCC rules on consensus that keep derailing COP after COP. It led me to organise a few thoughts on whether UNFCCC reform is still possible and what other pathways are/could be available.

With so many COP 30 eulogies, we need to ask if our toxic relationship with the climate change negotiations system is part of the problem.
