It's interesting how people will design buildings to withstand earthquakes because they can. But other dangers people simply accept as part of life because there's no easy way yet to predict or prepare, whether a lahar from Mt Hutt or Mt Rainier, an unpredicted tsunami or earthquake. Since I've grown up with these dangers they don't seem very significant to me. On the other hand tornadoes and hurricanes seem like very unreasonable dangers to live with, mostly because I never have.

Yes you are right on the NPV criterion. Infrastructure changes very slowly though... I figure that the three biggest impacts of climate change are: 1. Sea level rise. 3C rise in temperature should set off the melting of the Greenland ice cap. Might take 1000 years to melt though raising sea level 6-7 metres. Thermal expansion of the ocean would add to this. 2. Impact on ecosystems. Due to fragmentation etc. ecosystems can't migrate like they used to do. Ocean acidification kills coral etc. 3. Possible changes in ocean currents - I think the impact on Europe is overexaggerated even if it happened (Scandinavia would be badly affected with Stockholm being more like the Yukon territory... But the Yukon will be warmer anyway :) By the way it rained last week at Prudhoe Bay. Record above freezing temperatures for a few days... #1 has the biggest financial impact but under current institutional rules and discounting its value is essentially zero as you say. #2 isn't included in any of the big studies on global warming. Most studies focus on agriculture which is totally bogus (may affect some peasant farmers but commerical agriculture can just switch crops). David
