A glimpse inside
Climate Change as a Risky Gamble
Nordhaus frames climate change as a 'casino'—a metaphor for the unpredictable, high-stakes risks humanity faces as greenhouse gases accumulate. Unlike games of chance, the odds and potential losses are not fully known, making the challenge one of managing uncertainty as much as risk. This framing underscores the urgency of action: by continuing to emit greenhouse gases, society is effectively betting on outcomes that could range from manageable to catastrophic.
Economic Tools for Climate Policy
A central argument is that economics provides essential tools for addressing climate change. Nordhaus advocates for market-based solutions, especially carbon pricing, as the most efficient way to reduce emissions. He explains how taxes or cap-and-trade systems can harness market forces to drive innovation and lower emissions at the lowest societal cost, while warning against purely regulatory or command-and-control approaches.
