These two meetings are the culmination of long, intensive processes, and present governments across the world with the chance to make bold decisions. If they rise to the challenge, they can set us all on a path to address the inter-connected crises of poverty, inequality, environmental degradation and climate change.
I have a dream. It involves climate negotiators. They are bleary-eyed, exhausted, but happy.

Climate change is a huge threat to people, species, habitats and the places we care about. In a nutshell, that the risks posed by a changing climate are deeply concerning.
