It's not news to me. I know that the idea of AGW has been around a long time, and I noted as much in my post. It's the popular conception of it that I'm concerned with. It's like HIV/AIDS - It's a horrible disease, but popular fears of it made people with AIDS into modern-day lepers, without helping anyone. If we start rampaging around, enforcing naive but popular ideas for living "green", we're going to cause more trouble than we solve.
Take the idea of "Buy only locally grown produce". If that gains traction, you can expect movement away from factory farms, which eliminates the economy of scale and lowers farming efficiency. Overall expenditures on fuels, fertilizer, and other farm necessities will increase, diverting resources from other areas of production and raising prices. More arable land will need to be devoted to farming to produce the same amount as before, with consequent ecological damage and increase in land prices. Traffic on local roads will increase as food, fuel, and machinery shipments become more frequent. Local & state taxes/tolls will increase to pay for road maintenance. Carbon output may actually increase over the previous situation. This sort of idea is a middle-class indulgence, not a policy prescription for "green living".
