I think we ultimately ought to look to put all uranium enrichment and fuel reprocessing, if any is done, under multinational control. Those are the two technologies by which nuclear energy can be translated into nuclear weapons programmes.
People are seeing the impact of climate change around them in extraordinary patterns of floods and droughts, wildfires, heatwaves and powerful storms.
The whole climate is changing: the winds, the ocean currents, the storm patterns, snow packs, snowmelt, flooding, droughts. Temperature is just a bit of it.
Issues of energy, climate change, nuclear arms control and non-proliferation are all big deals. These are problems that we have to get right globally, not just nationally, and there are big benefits in cooperating, in terms of sharing costs, in terms of sharing risks, in terms of propagating the best answers.
It is economically irrational to exclude large environmental costs from the balance sheets of the producers and the consumers. You are only kidding yourself if you export those costs on to society as a whole.
