Certainly it is a worthy thing to study ways to provide security and resilience for our cities. However, if you start with an unchallenged belief in imaginary global warming, you are going to end up making things worse. Substituting wind or solar power for conventional power plants does not provide greater energy security, for obvious reasons. Worrying about fashionable, imaginary water shortages distracts from real urban problems such as crime or broken families. Worrying about food security is fairly comical given the obesity epidemic.
