Earth doomed! Hawking offers to pay deniers fares to Venus

Forget 2 degrees of warming, Hawking says “460″!

Oh, look, there goes another attention-seeking celebrity scientist — flaming out –watch the arc:

In the second episode of his new series “Stephen Hawking’s Favorite Places,” the British physicist warns Earth could soon become as hot as Venus if action to halt climate change is not taken immediately.

Now temperatures on Venus reach 250°C with powerful 300mph winds. Hawking says a greenhouse effect burned the planet’s oceans and lands, and that something similar could happen right here on Earth if climate change continues unabated.

“Next time you meet a climate-change denier, tell them to take a trip to Venus; I will pay the fare,” says the physicist in his show.

Sadly, Hawking is an atmosphere-denier. Venus’s atmosphere is ninety times denser than the Earth’s.

The lapse rate* just goes on and on through 60 kilometers of “air” and Venus ends up with a 467-degree surface, just like Earth would if it had an atmosphere this thick.

When Hawking yells “Venus”, I yell back “Mars”. Both have atmospheres of 95% CO2, but one is 467 degrees and the other is minus 40.

Hawking may say, “but the Martian atmosphere is thin”. I would say “Exactly“! It’s not the percentage of CO2 that matters most, it’s the thickness of the atmosphere.

On Earth, to get the same atmospheric pressure you need to get down about a kilometer below sea-level or 50 kilometers down a mine shaft, which is 40 kilometers deeper than anyone has ever dug.

Hawking can save himself the money for my fare to Venus, and get himself a ticket to Mars. He wants to go there anyway, so I’m doing him a favor.

Stephen Hawking is supposed to know some physics.

“Venus is like Earth in so many ways,” he explained. “A sort of kissing cousin.”

As I said, when I was a baby-blogger responding to DeSmog: Venus is not much of a twin for Earth:

…Venus is also 40 million kilometers closer to the Sun; it spins backward; a day lasts longer than a year; it has an atmosphere 90 times denser than Earth, and it’s hot enough to melt lead on the surface. All this AND the clouds are made of sulphuric acid.

It’s one hell of a ‘sister’ with acid rain at 475 degrees.

With an atmosphere 90 times denser than Earth, Venus is ‘like’ the Earth in the same sense that Bruichladdich Whiskey is ‘like’ water. They’re both clear liquids, but one will sterilize your bench top.

There is something truly tragic about being a physicist that’s ten years behind DeSmog.

*The lapse rate is standard scientific jargon for how much cooler the air gets as we rise up through the atmosphere.

    Look like he has been dropped on his head one too many times he is sounding as rediculous as Al Bore,,Leonardo DiCaprio and James Lovelock as well as E.O. Wilson and Peter Singer

    Sadly, Hawking’s myelopathy has apparently reached the brain. He had a blessed life considering that most similarly afflicted people would be decades dead.

    Hawking has said nothing of this.
    These are the statements of people who claim to speak for Hawking through interpretation of his catatonic state.

      I agree, and have been wondering about this for a long time.
      Who is verifying the interpreter??

      Then by the same token, you cannot claim that “Hawking has said nothing of this” .. how can you possibly know?

    I’m curious, when was this that Venus had “oceans” ??? .. ANY water at all? .. tell us, when was this? … Exactly when was Venus cool enough to be able to contain water?

    I’m so sick and tired of these asshats and their wild proclamations, and sicker still of the imbeciles that eat it all up without a question. The very notion that such a thing has ever happened is so patently absurd, a complete nonstarter. Stop it already! .. only someone with an IQ lower than a turnip is believing any of this sort of BS!

        Haha… thanks Al !! … I do work on it quite a bit. I’m somewhat of a golf junky. Actually, the term “somewhat” probably isn’t accurate. “Extreme” might be closer to the truth.

        Cheers!!!

    These idiots that fall Hook.Line & Sinker for this Global Warming/Climate Change poppycock are probibly the same suckers who bought into the Save the Rain Forests scam back in the 1990’s their what P.T. Barnum was talking about when he said THERE’S A SUCKER BORN EVERY MINUTE

    The recent researches of the scientist in this direction provide us with some data related to the increase of temperatures. However, they contain many contradictions.

    The habitual zone around a sun is defined as the area not so close that temperatures are too hot for life, and not so far away that it is too cold for life. Of course the actually distance depends on the solar output of each sun. At one time Venus was considered to be too close to the sun to be in the habitual zone. Now scientist have changed their minds. I’m not so sure that this was correct. I know an over riding factor is the density of the atmosphere, but high solar radiation might have been a factor.

      There’s no intelligent life on Jupiter, either.

    Hawking knows that:
    1. Mars has a similar CO2 concentration as Venus but is COLD, and
    2. That both planets have experience climate change WITHOUT humans.

    Actually going to Venus is not all that far fetched. There those who say people could live there in large air ship type constructs. The temperature is the same as earth at the same pressure. Which is about 50km from the surface.

    “I suggest to take a look at the above picture comparing temperature and pressure through the atmospheres of Venus and Earth. We see that for pressure between 10 and 1000 bar the temperatures are pretty much the same (the difference can probably be explained from the fact that Venus is closer to the Sun), indicating that the composition of the atmosphere has little influence at the same pressure, and that it is the large mass and resulting high pressure that makes the surface of Venus about 450 C warmer than that of the Earth.

    From the picture we can estimate an Earth-temperature of 15 C with Venus-atmosphere composition (2400 times as much CO2), and a Venus-temperature of 450 C with Earth-atmosphere composition. That is, no difference!”

    This arrogant posturing of the media-elected scientific elite has gotten out of hand. These people, like Neil deGrasse Tyson, et al, LOVE being fawned on my the left media while tipping cocktails and congratulating themselves on both scientific and political superiority. Tyson even has his own left-wing-celebrity-meets-like-minded-scientist ass kissing show on some cable channel.

    I’ve tipped a few cocktails with similar, but lesser known science scientists who assume I’m in their “club”. In private company the arrogance, vile language, and dismissal of anyone who would disagree as less-than-human is simply staggering. That’s why I nearly laughed my a$$ off when these same people respond in high dudgeon as Trump referred places like Somalia and Yemen as s#!+holes.
