    A Review of The Climate Casino:
    Risk, Uncertainty and Economics for a
    Warming World by William Nordhaus

    Robert Repetto

    For more than three decades William Nordhaus, Sterling Professor of Economics at Yale University, has contributed
    to a better understanding of climate change issues with three books and dozens of articles. He has consistently taken
    a judicious, balanced stance, acknowledging the many uncertainties while using the best available research findings,
    updating his analysis regularly and adopting mid-range estimates for key relationships. This approach has made him
    influential with policy-makers and an entire generation of climate economists.
    His current book, The Climate Casino, is written for a general audience and can be readily understood by non-specialists.
    Extensive documentation and technical matters are consigned to end notes. The book covers the entire range of
    climate issues: the science, impacts and damages, mitigation possibilities, domestic and international policy options,
    and politics. Where important controversies exist, Nordhaus fairly explains divergent viewpoints before introducing
    his own judgment. The book can be strongly recommended to everyone seeking to understand the climate problem
    and its solution.
    The book’s main messages are that humans are almost certainly causing climate changes unprecedented during the
    emergence of civilization, mainly by burning fossil fuels, and that the resultant warming is a major threat to societies
    and the natural world. Climate dynamics may well involve thresholds and tipping points that, if triggered, could make
    changes self-reinforcing and irreversible. The only genuine solution is to reduce emissions by changing the practices of
    billions of people, businesses and governments around the world. This can best be done through market mechanisms,
    specifically by creating an economic penalty or “price” for carbon emissions, either through a carbon tax or a cap-andtrade
    regime that limits the use of carbon fuels through tradable permits. Either option would be efficient, but the latter
    affords greater certainty over future emissions. In adopting targets under either policy, governments should consider
    both potential damages and the costs of reducing emissions, but should be willing to pay an insurance premium to
    stay on the safe side. Relative safety may be unattainable unless all countries with significant emissions cooperate to
    reduce them. If they do, climate change can be limited at a relatively low cost, less than one or two per cent of total
    income; however, waiting to act would be extremely costly. ...
