Basic Physics At NASA

Besides all the other BS in this tweet, the rocket scientists at NASA believe that melting sea ice raises sea level.  They should be sent back to elementary school to learn some basic physics.

NASA on Twitter: “The last 5 years have been the hottest in the modern record”

    NASA used to hire scientists. Now they hire idiots.
    God help the astronauts on our next space mission.

    • AndyDC says:

      They aren’t idiots, they are diabolical liars with massive political and financial backing.

      • arn says:

        You are right-
        they lie on purpose and pretend to be stupid,
        because stupidity and good intentions is the best cover for evil crimes.

        Anyway-NASA was about Rockets and Space.
        When did they all become doom&gloom salesme….climate expert??

  2. EternalOptimist says:

    This isn’t even basic physics, anyone who makes a cocktail understands this.
    NASA climate scientists , aspiring to bartender status

  3. DCA says:

    Someone should introduce NASA to Archimedes.

  4. ЯΞ√ΩLUT↑☼N says:

    What blatant propaganda. Maybe these dregs should move to the only cool spot they deliberately left unfilled for dramatic effect. They don’t sleep at night because they’re vampires.

    • arn says:

      So blatant and that i’m really surprised that there is no hammer&sickle on the photo.
      (the reds are so busy with saving us from the red color they use so much)

  5. Colorado Wellington says:

    I hope President Trump knows with whom he’s dealing when he makes plans

  6. DCA says:

    “The last 5 years have been the hottest in the modern record. This means that fire seasons are burning longer…”

    That is an incredible non sequitur. How long is the fire season in the Arctic?

    • ЯΞ√ΩLUT↑☼N says:

      I’m still trying to figure how a fire season can “burn”. Then somehow they’ve forgotten about their claims that cold also means global warming, but they warm the map regardless. They need jailing.

  7. GW Smith says:

    Imagery is all that maters. Those they want to convince don’t understand it. Our pointing it out is only heard by us. Keep it up, amigo!

  8. Bart Tali says:

    Melting sea ice can raise sea levels a little bit. It is due to the density difference between sea ice which is mainly freshwater and the denser salty ocean water it is displacing.

      Fear mongering. The author believes in wild CAGW theories and preaches waaaaay to passionately…

      Science isn’t absolute truth, but there’s a lot of scientists who are warning that sea level rise might become significant within the next few decades, and we should start preparing what we are going to do when the floods come. Scientists don’t have all the answers, but spending a little less time mocking their inquiry, and more effort trying to understand the basis of their theories, is going to be to your benefit. And, if you have children, to their benefit as well.

      Think of the children!

      Yeah, real sciency.

    • Ben says:

      The difference in density is so small it’s negligible.

    • DCA says:

      No wonder climate scientists can’t create models that are worth anything. If you can’t even grasp Archimedes, just pack it up and go home.

      Mr. Backoff errs by overthinking the issue. It’s deceptively simple.

      Any floating object – a log, a ship, a chunk of freshwater ice, a vast expanse of saltwater ice, whatever – creates a “hole” in the water (a.k.a. displacement). The surrounding water that would occupy that hole is EXACTLY the same mass as the object. And that is true regardless of the temperature of the object or the temperature of the water.

      Ice floats because of the density difference. It is already exactly displacing the volume it would occupy if melted. And thus the portion of the ice above the waterline is the volume that would go away if the ice melted.

      • Phil. says:

        True if the composition of the ice is the same as the water that is supporting it. However sea ice is usually less saline than the sea water so there will be a slight change when it melts. If you put ice cubes in a glass of salt water you will get a change in volume when it melts.

    • Bart Tali says:

      I meant to post a different link for the simple page. Here is what I meant to post:

      https://nsidc.org/news/newsroom/20050801_floatingice.html

      It is a small effect. That page says if all sea ice melted, it would raise sea levels by 4 cm or 1.57 in.

  9. Ari says:

    Look on the bright side- it’s only the 4th hottest ever!
    We are cooling!
    :)

  10. Paul says:

    6300 Temperature Stations on a planet 197,000,000 square miles. That’s a Temperature Monitoring Station for an area the size of approximately South Carolina and we are talking hundredths of a degree with a margin of error of tenths of a degree while adjusting the Data sitting at a desk. The reds are scary however.

  11. MGJ says:

    It all makes perfect sense just as long as you don’t think about it. As thought seems to have been completely removed from university curricula (you are only allowed to ‘think’ other people’s thoughts), I expect this tweet will be quite effective.

  12. Fire is fed by oxygen and extinguished by CO2.
    Fire trucks and fire fighter helicopters and planes run with fossil fuels.
    Melting floating ice does not sea levels.

  13. nejking says:

    I accidentally posted this under another post: NASA deleted the tweet. LOL. Good job Tony! They put up other propaganda instead.

  14. Colorado Wellington says:

    They aren’t the bold rocketeers of old, are they? Here is today’s NASA in its full glory:

    • Gator says:

      How does a season burn longer? Is climate change adding days to the calendar?

      I’m sure the Mercury, Gemini and Apollo astronauts are glad they had real scientists working on their rockets, instead of this crew of flakes and snowflakes. I’m trying to imagine anyone surviving a “renewable” powered rocket trip to the moon.

  15. GummansGubbe says:

    Good thing you saved the image of that thing. It is deleted now.

  16. Jl says:

    So they made no headway with number of acres burned, so now they’re going with “fire seasons that burn longer”?

  17. GCSquared says:

    “Besides all the other BS in this tweet, the rocket scientists at NASA believe that melting sea ice raises sea level. ”

    Believing in the alarmist BS isn’t necessary but it may help.

    A scientist friend he told me he couldn’t really discuss climate change with me because he didn’t have the time to look into it in depth. (This is pretty common. A lot of skeptics, Judith Curry for example, describe becoming that way when they took a close look.) My friend tended to go along with his alarmist colleagues simply on the basis of their competence in technical areas, which he assumed to apply to their judgment of climate.

    That’s sort of like believing that all good hunters know animal biology. They probably have quite a bit of incidental knowledge, but they’re also likely to be wrong about a lot. All “experts” suffer from the syndrome, “It ain’t what you don’t know that gets you into trouble. It’s what you know for sure that just ain’t so.” The cognitive trust you place in people (especially yourself) and ideas has to be re-examined continuously. Scientists don’t do that any more than the rest of us, but with some admirable exceptions, and just like the rest of us, most think they do.

    Relatively minor human weakness explains the behavior of climate scientists; but the deliberate deception of those in power who are exploiting that weakness, and that of the rest of society, lies at a much lower moral depth. Those are the ones that most deserve scrutiny, exposure, and public condemnation. Well, good luck.
