Dr. Hitterdale,
I read your essay with great interest. I agree with your suggestion that climate change be placed atop the global agenda. However, my view is that there is an "the elephant in the room" regarding climate change (and indeed, all other environmental and resource questions) that no one wants to acknowledge. Human population has overshot the sustainable global carrying capacity, and the top item on the global agenda for the next several centuries should be how to decrease back to a sustainable level. You may be interested in reading my essay ("Just Too Many People: Towards a Sustainable Future Earth").
