Abstract

As Thomas Schelling says, climate change is a «bundle of uncertainties», and in the last thirty years the range of uncertainty has increased. How much global warming will result from various levels of greenhouse gases? How will such levels affect climates? How will those climate changes impact on productivity, health, comfort, recreation and everything else? One of the greatest difficulties is imagining the kind of world we shall be living in when these climate changes begin to be serious, 50 or 100 years from now.
