As I have commented elsewhere, when is someone going to have the gumption to tie this particular problem to a possible solution to the Iran/Iraq/whereever strife by reducing global dependance upon oil for energy. The very big problem is of course that of air transport. Secondary after that is the difficulty of the internal transportation system - no not yer RV, but functions like getting food from production to city and mass city transport - and cheap heating.

But I do not believe that is enough. My great fear, after listening to Stern’s speech and some of the interviews that followed (political, scientific, supporting, against) is that once more we (humanity, or those able to) may have completely under-estimated the impacts of global warming. Nothing to do with cause… just effect.

Instance in point must be Australia; some parts of the country have not had rain in 6 years. That is unprecedented in the past 150 years (I believe) of reliable weather records. This is impacting on farmers, and even some of the major cities are running short of water. We were in Cairns four years ago and the main city reservoir was only 30% full. The headwaters of the Barron River system were dry, with the major hydro power station at Cairns operating at about 15% capacity as a result.

And so it goes…
