  1. Paul Whyte Says:

    Well I’m usually impressed by Hansen but that in such a short period of time covers both the problem and a good start on the solutions.

    His point that a carbon price needs to be implemented by conservatives I found the cherry on the top!


  2. And Hansen gets in several plugs for the most feasible option in the whole portfolio.

    At $10/ton of CO2, the carbon tax is roughly equivalent to a 2.2¢/kWh PTC advantage over coal.

    At $20/ton of CO2, the carbon tax is roughly equivalent to a 2.2¢/kWh PTC advantage over natural gas.

    By the time it hit $30/ton, the former owners of Vermont Yankee, Kewaunee and San Onofre would be kicking themselves for ever thinking about shutting them down.

    Since burning one gallon of gasoline produces about 20 pounds of CO2, the tax would be about 10 cents per gallon at the $10 /ton rate. Not enough. And whatever the rate may be, we needed the carbon tax yesterday. Any bets on when it will be enacted? And how many “conservatives” will be on board?

    All in all, another good presentation by Hansen, with some discouraging graphs—-particularly #3, which shows that coal is having a worldwide resurgence that is outpacing conversion to renewables.

    India and China hold 1/3 of the human population of the planet, and they are the ones that need to deal with their future carbon emissions. The past footprint of the US and the West may be what has gotten us to our present sorry state, but future success or failure lies mainly in the East.

    PS to E-Pot. Really getting into the Atomic Accidents book. Did you know that the first reactor explosion can be credited to Nazi scientists during WW2, although the first radiation deaths were of Manhattan Project bomb scientists in the U.S.?


    • In re: alleged Nazi nuclear explosion, are you referring to this?

      Conventional explosives are used in the compression systems of implosion bombs, and they’re quite capable of causing damage and killing people even if not a single nuclear fission occurs.  It’s pretty safe to say that if there isn’t any residual nuclear material from a fission explosion at the German site (U-236, Sr-90 and Cs-137 would be biggies) then it didn’t occur.  The criticality accidents in the USA did not have any explosive yield worth mentioning.

        No, “this” link sounds like total BS by a guy who is trying to sell books. Two tons of conventional explosive would make a pretty big bang by itself, if this event even happened. All that’ I’ve read leads me to think that the Germans were nowhere near achieving a fission bomb.

        What I’m referring to is, just as I said, is an actual “reactor explosion” that occurred on June 23, 1942. The uranium in a reactor named L-IV caught fire and the reactor then exploded (steam, non-nuclear)—-it burned for two days. Werner Heisenberg was the head scientist on the project

        And the criticality incidents in the USA didn’t have ANY real explosive yield—it was the burst of radiation that killed the folks—some took such high doses they were dead in two or three days.
