Who has a moral responsibility to slow climate change?

The current humans are the first ones to recognise that action is required on climate change, but the urgency makes us also possibly the last generation to be able to act before major threats are aggravated. I applaud the general message of an urgent call for action in Shue’s book but find that the brushstrokes used for identifying those responsible are a little too broad. The reason for this is twofold. Firstly, it is questionable as to how many of us really know enough about the risks we are leaving future generations with. Secondly, discussion in terms of generations underplays the big differences between the responsibility of different groups of actors within them.
