    What should be done in short-term, within decade or two? Should we only wait the fruits of efforts on techological transition? Or may be land-use changes and forestry could be of some help?

    You suggested that global diplomatic action has very rarely been successful in the past.  In the atmospheric community one global success stands out, that of the Montreal Protocol on Substances that Deplete the Ozone Layer.  Do you view this success as an anomaly?  If so, why?

    Graphs in this talk show that our use of oil and natural gas currently accounts for two thirds of the carbon currently injected into the atmosphere.  While acknowledging the upcoming Hubbert's Peak in oil and gas, both David and Jae before him dismiss this as a mechanism for reducing our CO2 emissions because of the huge reserves of coal and methane hydrates.In looking at the long time series evolution of our use of fuels -- wood, coal, oil, nat gas -- they have missed the very important concept of Energy Returned On Energy Invested (EROEI).  A 300 year time series of EROEI shows a dramatic rise and peak in the earl part of this century when the US oil patch produced EROEI of 100:1.  Offshore rigs of the last two decades have an EROEI of 20-30 while Alberta tar sands are somewhere in the range of 1.5-2:1.  Clearly, our use of fossil energy will stop somewhere before EROEI of 1:1.It is important to notice that the history of banking closely follows the development of the industrial revolution.  Financial energy is measured in a similar fashion as Capital Returned On Capital Invested.  Over the last few centuries the amount of capital avialable for investment has risen in concert with our consumption of energy.  This centuries decrease in the energy intensity of the economy has allowed availabe capital to increase even as EROEI has decreased.My question is:  At what point does EROEI couple with CROCI in a negative fasion so as to reduce our use of fossil fuels through demand destruction.

    Can you further describe the concept of "richer is safer"?
