I believe it was world something or other day in the US yesterday so with that in mind:- What would it take for the US to sign an agreed protocol to help combat climate change? I read recently that the US has a population of 298 million roughly yet produces more CO2 than Europe population 450 million or so by about a billion tonnes of CO2 per year. Now I don't want to start *****ing at the US for it's backward approach to ecology, sure you get plenty of that already. A simple question, what would it take for the US to take golobal warming seriously or at least seriously enough to sign a Kyoto like protocol? I know trillion dollar defecit and all that? But really is at a matter of never or just when?
