  People are stupid. Let’s keep our hands off geo engineering.

    And do what?

      Step one: invest in nuclear power and renewables

      Step two: stop taking carbon from outside the carbon cycle and putting it into the carbon cycle

      Step three: use the abundance of energy from self-heating rocks to take carbon out of the carbon cycle

        Your "step three" is geoengineering.

        As long as they are operated by for-profit entities who are more than willing to ignore safety procedures and best practices, and lobby for lower safeties, nuclear energy cannot be safe, regardless of the underlying technology.

        Let’s be honest, renewables are already geoengineering (changing water flow, air flow, albedo, etc.), just done in an uncontrolled fashion. Nuclear energy or renewables do not solve the long term problem unless coupled with large scale geoengineering. Granted all of the above are vast improvements over fossil fuels.

        Thermodynamics is a bitch. If you make a nuclear reactor, you make heat. You add additional heat to the system, either at the source (energy production isn’t 100% efficient), or at the point of consumption (the waste product of using energy is always heat). So, if you switch everything to nuclear, you’re still adding heat to the system that wasn’t there before (in addition to whatever the sun is blasting us with). If energy use goes up, and it always does, it just means we add more heat faster.

        Literally the only way we can have our cake and eat it too is geoengineering. Solar shields in the earth-sun Lagrange point are my preference and least disruptive to other natural processes.

      Reduce emissions. That’s cheaper, more effective and safer than any other method.

      Geo engineering commonly only tries to fix temperature. While that would be a big achievement, it does not change the CO~2~ ppm. And that translates to ocean acidification. Which translates to mass extinctions. Which is still an existential threat also for land living species, and us.

      There is only one solution to fix both (and many other, related / caused problems): Fix the source.

      We cannot engineer our way out of all the individual symptoms. Just leave fossil fuels in the ground.

        I don’t think we can reduce emissions fast enough though. 2050 seems a long way away.

        There are ways to capture carbon in seawater, kelp is the fastest growing I know of.

        We need many solutions, not one.

      Put paper bags over our heads and lie down.

    I wrote a similar conclusion back in 1996, not so much changed in that discussion, it’s a distraction.

  IQ tests are designed relative to the population so the median is always (or should always be) 100. The point is that is measures people against one another in the present. If we all got 10% smarter, our individual IQ scores would stay the same.
