BriPat -
What "planning" are you proposing to do that hasn't already been done?
Exatly what most countries are doing - analyzing land use in terms of climate change trends. What pests might be more prevalent than they were 10 years ago? Will rainfall rise or fall? What species of trees or crops or livestock would cope best with those changes?
I could be wrong, but I suspect that Luddite-thinking means the US is a good 10 years behind other countries in this area.
Once again - the cost of denial may be very, very, very high.
A new car may be more reliable, but it's not cheaper.
In the long run, it may well be cheaper as well - we would only know that from a case-by-case analysis.
But all infrastructure needs to be replaced at some stage, and the longer the US waits before investing in infrastructure, the more expensive it may be.
It's not just the cost of buying a tidal turbine - it is the fact that you will need to buy them from countries who were on to this idea 20 years ago. They created the jobs and earn the export dollars the Luddites in the US sniff their noses at. Sure, the US can build them too, but you are 20 years behind the likes of Scotland on that learning curve.
Ok, so Germany pays more for electricity than the US does right now. Germany also produces one in every three windmills sold...and in an industry that is only just starting to real make profits.
