An excellent piece here. I\’m not sure I agree with his conclusion but I do like his argument:
Personally, I doubt whether the utilitarian calculus is the right ethical framework in which to think about global warming. It gives us numerical answers, but it just does not feel as though the calculus captures my concerns. Take the valuation of the future: are we radically undervaluing the interests of future people?
Of course, we cannot tell how the future will feel, but one simple test is to ask ourselves how we feel about the past – are we angry that our great-grandparents did not live more frugally so that we would now be richer? Personally, of all the things I would have liked my great-grandparents to do differently, this is not one of them. However, you may feel differently.
And, of course, how will our great grandchildren feel about us? The same?
