So there's no serious problem. CO2 levels aren't going to be higher than in recent times any time this century: <Based on current trends, carbon dioxide concentrations are likely to increase to 500PPM this century. The last time the planet experienced levels as high as 500PPM was about 20 or 40 million years ago, when sea levels were 100 metres higher than today. > Over 100 years, a sea level rise of 100 metres is no big deal either. There is plenty of land that far above sea level. Aquaculture would have a LOT of scope with shallow seas everywhere. That's assuming that happened, which doesn't seem likely according to computer models of sea level rises expected. I thought expected rises were more like 5 metres. There isn't much left of cities from 100 years ago. They regenerate faster than that. Buildings are old after 40 years. Rebuilding would give a chance of redesigning into a more modern form in better locations. Most cities are where they are for irrelevant historical reasons. They are there because that's where they are. Their network effect is powerful. Like the imperial system of weights and measures in the USA, people just keep doing what they have always done, even if it's senseless. Mqurice
