Heating Your Greenhouse At Night

Temperatures on the dark side of Venus are just as hot as the lit side, so it should be obvious to anyone capable of rational thought* that the “Greenhouse Effect” does not make Venus hot.

*This would apparently exclude James Hansen and Carl Sagan.

If Earth’s N2/O2 atmosphere was as thick as Venus atmosphere, Earth would be as hot as Venus.

    Unbelievers should use the in flight entertainment center during their next air travel. It doesn’t matter where you are in the world, as you climb to altitude, temperature drops to (around) -100 F.

    • Billy Liar says:

      -55°C = -67°F
      (not -100°F; you forgot to add 32)

        The machine will usually toggle between Celsius and Fahrenheit. So, I’m not converting.
        If the instrument is not working properly, I wouldn’t know. Temperatures as you suggest above do appear commonly on the system. -100 F is the lowest I’ve seen. Typically above 40k ft.

      • Billy Liar says:

        -100F is -73C; the stratosphere is isothermal at -56.5C up to 65,000 ft in the international standard atmosphere so at -100F it would be ISA-16.5C. That’s pretty cold. You must fly over (or near) one or other of the poles a lot. 🙂

    It takes 243 Earth days for one ‘day’ on Venus. Venus’ rotation is one of the slowest in the Solar System.

    That’s alot of noonday sun. 😉

    Steve,
    There is currently far far more N2 and O2 than CO2 in Earth’s atmosphere and yet their contribution to the greenhouse effect is dwarfed by the much smaller concentration of CO2. There is no logic to your assertion that greater pressures of N2 and O2 would create a Venus type atmosphere on Earth.

    • tckev says:

      This has already been pointed out recently by physicists Gerlich and Tscheuschner, who have written succinctly, “…since the venusian atmosphere is opaque to visible light, the central assumption of the greenhouse hypotheses [sic] is not obeyed.”

      But you missed the entire point that Venus is NOT the temperature it is due to an “out of control” greenhouse effect. The greenhouse effect in other words does not control the temperature of this planet as much as other factors. We can debate the actual reason, but some facts we do know about the planet include such tidbits as this:

      Instead of several major wind systems and inefficient storms such as on the Earth that transport heat, Venus tends to have one very hyper efficient heat transport system that keeps the night side a similar temperature as the day-side. This also equates into a planet that with similar temperatures on the night side (which is night for over 200 days) that the heat trapping capacity of greenhouse gases is not applicable to the nightside at all. This is the point you seemed to miss in the article. How is Venus staying warm predominantly without the greenhouse effect? The day side obviously has this effect to some extent, but the fact that heat is transported to the other side of the planet where it can easilly escape is proof that there is some other reason to the warmth of the planet. Another interesting tidbit, the planet gives off more heat than it receives from the sun. Most of the sun’s energy in other words is reflected back out….

      Although adding N2 and O2 to the Earth would probably warm our planet quite a bit as I would guess due to more efficient heat transport, I don’t know if the water effect which works to moderate the temperature on this planet wouldn’t also moderate the temperature at increased pressures. That is a question for astrophysicists who are not completely incompetent like Dr. Hansen.

    And if Earth was 26 million miles closer to the sun.
