Test Someone’s Climate Knowledge with Five Easy Questions

testIf your friends can’t understand why you don’t believe in manmade global warming, give them this simple, five-question quiz. They may realize they don’t know as much about global warming as they think.

1. The primary greenhouse gas in the atmosphere is:

[a] Nitrous Oxide

[b] Carbon Dioxide

[c] Methane

[d] Water Vapor

2. Carbon dioxide comprises what percentage of the Earth’s atmosphere?

[a] 400%

[b] 40%

[c] 4%

[d] 0.04%

3. When reviewing our planet’s long geologic history, the current level of carbon dioxide in the atmosphere is:

[a] Among the highest levels ever recorded

[b] Among the lowest levels ever recorded

[c] About average

4. Each new molecule of carbon dioxide added to the atmosphere traps:

[a] The same amount of heat as the previous additional molecule

[b] More heat than the previous molecule

[c] Less heat than the previous molecule

5. In the twentieth century, solar output was:

[a] The same as it’s always been

[b] The lowest in 1,000 years.

[c] The highest in 1,000 years.

ANSWERS:

1. [d] Water vapor. Roughly 80% of the Earth’s “greenhouse effect” is sustained by water vapor.

2. [d] 0.04%. Carbon dioxide is a minor constituent in the atmosphere, which is dominated by Nitrogen (78%) and Oxygen (21%).

3. [b] Carbon dioxide levels are currently among the lowest ever recorded in Earth’s 4.5-billion-year history.

4. [c] Less heat. Carbon dioxide follows a logarithmically declining function. That means, it exponentially loses the ability to trap heat as its concentration increases.

5. [c] The highest in 1,000 years. Starting in the latter part of the 1800s, solar activity ramped back up to the peak output previously seen during the Roman Warm Period (250-400 AD) and the Medieval Warm Period (950-1250 AD).

If you get more than two answers wrong, start reading Climate Change Dispatch regularly for a crash course in climatology.

    This is perfect for my know-it-all media-slave friends!

    I copied the post to my I-phone notes to make their heads explode at those opportune moments…

    I wish this were available in a business card size to leave behind.

      Suggested 6th question:

      CO2 is

      1. A noxious gas

      2. Particulate matter that contributes to global warming

      3. A necessary plant nutrient

    Every Senator should know the answer to all 5 questions . Do they ?
    No chance .
    Good idea because as they say …”the fewer the facts the stronger the opinions ‘ .
    But a better one for Senator Whitehouse to ponder is the one from Mark Twain
    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 .
    Yep climate changes , hopefully it keeps warming .Humans , animals and especially natural variables drive the climate bus just like they always have .
    If there was no money in the climate fear industry the world would be able to
    solve some real environmental and social issues . It’s not like there is a shortage is there ?

    Only got 4/5 myself so hahaa..

    Got Q3 wrong. So how long is a piece of string. Its a bit vague without an actual timeframe.

    The definition of denier in the climate caper are those (like me ) who deny the sales pitch for wasting ” $ Trillions” on an” Opportunity ” to pay conmen and grant seeking business interests based on their over hyped climate Armageddon propaganda .
    Climate changes , it is warming thankfully , and humans must have some influence both positive and negative . When $Trillions of other peoples money (debt in most cases ) is up for grabs it pulls out the worst in some .
    Proudly a DENIER .

    I thought CO2 was 4% of the earth’s atmosphere and man made CO2 4% of that

      Michael, carbon dioxide is 0.04% of the earth’s atmosphere: 400 parts per million is the same as 40 parts per 100,000, 4 parts per 10,000, 0.4 parts per 1,000 and 0.04 parts per 100 which is the same as 0.04%. And yes, the human contribution is, at most, 4% of that 0.04%; the UN IPCC calculates it at around 3% of that 0.04%.
      Check the deception: http://www.ilovemycarbondioxide.com/archives/IPCC_deception.pdf
      And, by the way, there is no atmospheric greenhouse effect at all. The entire article is quite mis-informed. It is thermodynamically impossible for radiation to make an emitter of that same radiation any warmer by means of sending that radiation back to its source.
      There are some 65 version of the “greenhosue effect” and all are wrong.

        Many thanks for that. So in effect man made CO2 is minute. I gather the Main argument for man made global warming is an increase in CO2. It that is their thesis then I can’t understand how hat can be true given the minute amounts of CO2. Have I understood this correctly.

          Yes Michael, you have understood it correctly. More and more high-level bureaucrats are coming out to steate quite openly that AGW was never an issue; all the wanted to do is curb capitalism, preserve resurces and estabish a world government under the UN. See Agenda 21 by the UN. AGw never had anything to do with CO2, that was just a sinister plot by sinister people who are running this world of ours.

            Exactly right, Hans Schreuder. I wonder why those who share a belief in AGW never notice that they alsol share the same political view as well. Does that not make them suspicious of their scientific superstitions?

    I disagree with #4.
    The logarithmic reationship is a contrived relationship. IMO.
    There is no empirical proof [that I am aware of] that this curve is true.
    Question: how does one take real measurments in the atmosphere, from zero to infinity, to obtain this curve’s relationship in the real world??

        Yes Steven, therein lies the problem: “laboratory exeriments”. All done, out of necessity, in an enclosed space. That’s the only space where a “greenhouse effect” can be observed and it has nothing to with radiation. It has everything to do with restricted convection and as there are no solid barriers in the open-to-space atmospere there is, by definitin, no “greenhouse effect” in the open atmosphere. In the open atmosphere there is no “heat trapping” by CO2 and in any case, just on logic alone, if heat is trapped, then that’s it, just like latent heat, which does not increase the temperature of the substace that is absorbing the heat. QED.

      The atmosphere is a physical equilibrium system and adding CO2 reduces H2O which is a far better absorber of infrared radiation, heat energy, than CO2 and thus cools the atmosphere. The effect of adding CO2 as now claimed is upside down. The truth is very simple:

      CO2 is a “trace gas” in air and is insignificant by definition. It would have to be increased by a factor of 2500 to be considered “significant” or “notable.” To give it the great power claimed is a crime against physical science.

      CO2 absorbs 1/7th as much IR, heat energy, from sunlight per molecule as water vapor which has 188 times as many molecules capturing 1200 times as much heat producing 99.9% of all “global warming.” CO2 does only 0.1% of it. Pushing panic about any effect CO2 could have is clearly a fraud.

      There is no “greenhouse effect” in an atmosphere. A greenhouse has a solid, clear cover trapping heat. The atmosphere does not trap heat as gas molecules cannot form surfaces to work as greenhouses that admit and reflect energy depending on sun angle. Gases do not form surfaces as their molecules are not in contact.

      The Medieval Warming from 800 AD to 1300 AD Micheal Mann erased for his “hockey stick” was several Fahrenheit degrees warmer than anything “global warmers” fear. It was 500 years of world peace and abundance, longest ever.

      Vostock Ice Core data analysis show CO2 rises followed temperature by 800 years 19 times in 450,000 years. Therefore temperature change is cause and CO2 change is effect. This alone refutes the anthropogenic global warming hypothesis.

      Methane is called “a greenhouse gas 20 to 500 times more potent than CO2,” by Heidi Cullen and Jim Hansen, but it is not per the energy absorption chart at the American Meteorological Society. It has an absorption profile very similar to nitrogen which is classified “transparent” to IR, heat waves and is only present to 18 ppm. “Vegans” blame methane in cow flatulence for global warming in their war against meat consumption.

      Carbon combustion generates 80% of our energy. Control and taxing of carbon would give the elected ruling class more power and money than anything since the Magna Carta of 1215 AD.

      Most scientists and science educators work for tax supported institutions. They are eager to help government raise more money for them and they love being seen as “saving the planet.”

      Google “Two Minute Conservative” for clarity.

    What this so perfectly demonstrates is how easily public “knowledge” can be manipulated by media and popular culture. Climate science in the public realm has been reduced to a series constantly repeated wive’s tales.

    The whole thing is fueled by the human desire to be recognized as someone who is “informed and caring” in the public square. Now we’ve ended up with this head-nodding circle-jerk of feel-good self-congratulatory nonsense.

    I couldn’t choose an option for questions 1 and 4, because there’s no such thing as a greenhouse gas!

    Senators that can’t answer these basic questions are not being informed . Why is that ?
    How many newspaper Editors could get these questions right ? The answer it doesn’t matter . Scary global warming is a produce wrapped in fear and sold with guilt .
    The truth is irrelevant when it fails to help sell a product that is now a
    $7 Trillion OPPORTUNITY according to banker Mark Carney .

    Come on folks step right up … buy GREEN TONIC ..satisfaction as guaranteed as an ice free Arctic . Save the Planet .

    CONSIDER THE ASS
    WHO THOUGHT GAS
    WAS LIKE GLASS
    AND BELIEVED THAT THE SKY
    WOULD TRAP HEAT AND HE’D DIE

    Stir estimates together
    and make some numbers crunch
    and soon you’ve got a science
    and more than just a hunch.

    From reading all of this
    it’s now quite clear to me
    that if you add up guesses,
    you get a certainty
