Just When You Thought Scientists Couldn’t Possibly Get Any Stupider …

Hawking attacks Trump: US president will cause ‘250 degree temperatures – like VENUS’ | Science | News | Express.co.uk

450 million years ago, CO2 levels were 10X current values and Earth was in an ice age.

Venus is hot because it has an atmospheric pressure almost 100X that of Earth. The same reason why the top of the Grand canyon is cold, and the bottom of the Grand Canyon is hot. Temperatures in Venus troposphere at the elevation where pressure is 1 bar, are similar to earth.  Only a complete moron would believe that adding 0.0001 mole fraction CO2 to the atmosphere would cause that.

Enter Carl Sagan and Steven Hawking.

Every climate scientist in the world knows that Hawking’s claim is complete garbage, but none will speak out because they hope to benefit from his stupidity.

    Even ignorantly ignoring Venus’s 2802 hour long days, the biggest reason Venus is the way it is, is because it doesn’t have a stable axes of rotation. Which thanks to our Moon, Earth does. So at different points throughout it’s history, parts of Venus has had year round Sun…

      Nighttime temperatures on Venus are about the same as daytime temperatures. The heat is due to the thick atmosphere, not the small amount of sunlight which reaches the surface.

      • mat says:

        I’m speaking to the make up of that atmosphere. “the biggest reason Venus is the way it is”. In other words, without the Moon, especially if you subscribe as I do to the Giant Impact Hypothesis, the Earth and Venus would have similar atmospheres. And be almost the same size…

        • Weylan McAnally says:

          Tony is referring to the fact that incoming energy at the top of the atmosohere and atmospheric pressure at the surface are what determine the average surface temperature of any planet or moon. Venus receives much more energy from the sun AND has 91 times the atmopheric mass than the earth. The composition of the atmosphere is irrelavant. This is why idea of CO2 causing any climate change is laughable.

          • cdquarles says:

            The composition does matter, for the bulk atmosphere’s heat capacity is determined by the mole fraction of each component and each component’s heat capacity. That said, in the case of Venus, its proximity to the power source and high mass atmosphere do matter more than the composition does as a first approximation.

    I does make me wonder: Given Stephen Hawking’s condition, could someone not simply write something (even from his computer) then send it out with his name on it, without his having either knowledge or, or any way to prevent? I’ll admit that I’m simply reacting out loud to this, but he is in pretty rough shape…and he does have kids and others/handlers around him with access to him and his email. I don’t think he can author any papers w/o help, but I’m not 100% sure of that. Anyhoo. Happy 4th.

    Genius does not preclude stupidity; wisdom comes in knowing when to shut up and keep the spark of genius alive.

      well said

    • Colorado Wellington says:

      It’s tragic that just as our civilization relies more than ever before in recorded history on science and technology, people like Hawking join the global warming clowns and undermine people’s trust in scientific expertise.

    • mat says:

      It’s the mistake we all make at some time. Which is to assume that because we are/appear smarter than most on a given subject, that that “smartness” applies to all things automatically…

    Global warming in action…

    The mercury in the NSW town or Deniliquin , close to the Murray River, sank to -5.6C early on Sunday morning — that’s the coldest it’s been for 110 years.

    ‘Only a complete moron…’ or a complete propagandist with a hidden agenda?

  6. Edmonton Al says:

    Stephen William Hawking, CH, CBE, FRS, FRSA is an English theoretical physicist.
    The operative word is “theoretical”.
    Need I say more?
