Blueprints For Taming the Climate Crisis 389

Posted by Soulskill from the pump-all-of-our-smog-into-the-sun dept.
mdsolar sends this story from the NY Times: Here's what your future will look like if we are to have a shot at preventing devastating climate change. Within about 15 years every new car sold in the United States will be electric. ... Up to 60 percent of power might come from nuclear sources. And coal's footprint will shrink drastically, perhaps even disappear from the power supply. This course, created by a team of energy experts, was unveiled on Tuesday in a report for the United Nations (PDF) that explores the technological paths available for the world's 15 main economies to both maintain reasonable rates of growth and cut their carbon emissions enough by 2050 to prevent climatic havoc. It offers a sobering conclusion: We might be able to pull it off. But it will take an overhaul of the way we use energy, and a huge investment in the development and deployment of new energy technologies. Significantly, it calls for an entirely different approach to international diplomacy on the issue of how to combat climate change.

      Consider that on the one side we have a revealed religion that depends on global climate models that embody all they think they know about climate. The GCMs really do not seem to work.

    We need to do several things in the US to help ourselves, as well as push other nations.
    We would be better off stopping subsidies on solar, and allow wind to expire in 2 years. Instead, we should now focus those subsidies on nuclear power (our own), along with electricity storage.
    Then require that all new construction below 5-6 stories will have on-site AE that will equal or exceed its HVAC usage.

    In addition, we need to put a tax on all consumed goods (including those shipped from overseas), based on the MAX CO2 that went into make it. The tax should start low and raise every 6-12 months. This will give time to all nations and states to make long-term choices.
    Basically, the tax is applied to all goods, unless you register where it and its parts come from. Then if you get the parts from nations/states where the CO2 is lowest, you get lower taxes.
    To make sure of the CO2, rather than the wild estimates that we have, we use the OCO2 which will show emissions production, along with movement, around the world.
    Finally, to normalize it, we use $ GDP / tonne of CO2. The higher the $GDP, the better.

    The above is all that is needed to force us to change, and give us time. Not just America, but all nations since America is the world's largest importer.
