A major researcher on global warming, based at a research center in California, wrote to me today, re my polar cities PR campaign and images online:

"Dear Dan,

I think it is nice to have creative visions of the future, and thinking about polar cities certainly raises a host of interesting issues.

If we think of your work as an exercise in prediction, then I think it somewhat lacking.

If the goal is to get people to open up their vision of possible futures, then it seems as if you are having some success.

I am not sure if it is the most efficient way to focus discussion, but it is another novel way of focusing discussion so adds to the overall mix. Good luck with your quixotic venture !!"
