John Broome (Oxford) gives a talk (3 May, 2013) titled "The public and private morality of climate change". Abstract: This talk takes up two important topics within the public morality of climate change. First I shall discuss the notion of 'dangerous anthropogenic interference with the climate system', which regulate much of the public debate. Then I shal discuss the possibility of a solution to the problem of climate change that requires no sacrifices from anybody.
