Mr. Janssen, it might be instructive for you to view US fossil fuel energy consumption vs time.  We have reduced the amount consumed by only a few small percent including the time span in which your rational sensitive President Obama was in office.  The sad news that you probably haven't heard is that global warming can only be stopped by nearly 100 percent reduction in the use of fossil fuels to generate energy.  Of course a 50 percent reduction would slow warming a bit but not stop it.  Unfortunately, massive elimination of fossil fuel use would radically change our society and the costs we the people would have to bear would be dreary.  I suspect that most warmers are not really educated about how massive the problem of stopping CO2 build-up is.  I further suspect that you and many like you would be personally unwilling to make the sacrifices necessary to drastically reduce fossil fuel use.
