Where is the Nash Equilibrium on Climate Policy. Here is how I see our options.

1. Agressive actions are needed now on the chance that things will get worser faster – a risk we cannot take
2.We can wait – the GW equivalent of ‘watchful waiting” cancer therapy.
3. We can worry at the margins – recycle more -reduce our carbon footprint some – be smart shoppers and good global citizens.
4. We can treat Giai as an adaptive organism – drought in Houston will be offset by robust harvests from Moscow.

Actions impose costs – and what are the thresholds where imposing those costs make sense…

Is there a certain amount of hubris in the idea that we can actually affect the climate. If we believe in the darwinian model there were certainly times when the planet was much warmer – the Greenland era being one of the most recent – and much cooler – the Christmas Carol era in England when snow fell regularly in London and the Thames froze over for ice skaters..
