The Paris summit ended with an agreement, fortunately. Not good enough to save our grandchildren from climate disaster, but at least a beginning, which we hopefully will be able to build upon. Apart from the climate change deniers, who live in their own claustrophobic world, much of the disagreement is about justice: which are the countries to blame, and which should clean up their acts first? The Paris summit tried to avoid the question of justice and convince us that we all have to contribute, including the developing countries. And the developing countries seem to have gruntingly accepted that.
