To Gain Attention the Climate Alarmists Go to Extremes

Science is not supposed to mislead. It’s supposed to be precise. Rigorous. Circumspect.

But in recent years, something sneaky and unethical has occurred. Officials have begun talking about the worst-case climate scenario is if it were our likely future.

More than a decade ago, the Intergovernmental Panel on Climate Change developed four fairy tales to describe how humans might impact the climate by the year 2100.

There was an optimistic scenario, two mid-range scenarios, and a pessimistic scenario. The latter is known as RCP8.5 (I think of it as Ridiculous Climate Prophesy 8 dot 5).

In January, Zeke Hausfather and Glenn Peters published a comment in Nature reminding everyone that RCP8.5 isn’t a realistic vision of the future.

It represents an unlikelyhigh-riskdystopian world (their words) in which “the dice are loaded with the worst outcomes.”

It can’t become reality, they point out, unless humanity burns five times more coal than we currently do, “an amount larger than some estimates of recoverable coal reserves.”

Whenever RCP8.5 gets mentioned, they say, it should be clearly labeled as an “unlikely worst case.”

Their plea is unmistakable:

We must all – from physical scientists and climate-impact modellers to communicators and policymakers – stop presenting the worst-case scenario as the most likely one. [bold added]

US climate analyst Roger Pielke Jr. has similarly written a trio of articles that document how RCP8.5 “moved from an extreme outlier to the center of climate policy discussions,” corrupting great swaths of the scientific literature along the way (see herehere, and here).

He, too, calls the RCP8.5 vision of the future imaginary and impossible.

Canadian economist Ross McKitrick is also ringing the alarm bell. RCP8.5, he says, is “a scorcher that predicts historically unprecedented increases in global CO2 emissions.”

Using words such as implausibleimprobableexaggerated, and distortion, he makes it clear the only place this vision of the future exists is in fevered imaginations.

“No one seriously believes,” he says, that the increase of coal consumption described by RCP8.5 “is even possible.”

Even journalists who’ve hyped the climate threat are wising up. In an article titled We’re Getting a Clearer Picture of the Climate Future – and It’s Not as Bad as It Once Looked, David Wallace-Wells reports that most experts he’s interviewed “told me that they did not see RCP8.5 as a plausible scenario.”

By the year 2100, remember, teenager Greta Thunberg will be 97 years old. Wallace-Wells observes that any attempt to predict what the world will be like that far into the future is really just “a foolish game.”

In his words:

Projecting what global energy use will be in the year 2100 is the equivalent of trusting projections made in 1940 about where we are today.

Yet that is what much of climate ‘science’ – and climate ‘journalism’ – now amounts to. In 2018, the front page of the New York Times announced: U.S. Climate Report Warns of Damaged Environment and Shrinking Economy.

It began this way:

A major scientific report issued by 13 federal agencies on Friday presents the starkest warnings to date of the consequences of climate change for the United States, predicting that if significant steps are not taken to rein in global warming, the damage will knock as much as 10 percent off the size of the American economy by century’s end. [bold added]

Incredibly, that ‘major scientific report’ takes RCP8.5 seriously. Calling it a “core scenario,” page 6 of the report presents it as a realistic possibility rather than a farfetched hallucination:

RCP8.5 is generally associated with higher population growth, less technological innovation, and higher carbon intensity of the global energy mix.

This means the report is junk. No matter how many federal agencies were involved in its creation. But the Times didn’t tell readers that.

    “RCP8.5 (I think of it as Ridiculous Climate Prophesy 8 dot 5).”

    And based on modelled nonsense.
    These models don’t even begin their calculations from a known starting data point — current weather data, or recent past climate data. No they are fed politically adjusted nonsense, and when any of the model(s) show unwanted outcomes they are ignored (or maybe reset?).
    Climate Science is the pinnacle of an anti-science methodology — adjust the data to fit the theory.

    “It can’t become reality, they point out, unless humanity burns five times more coal than we currently do, “an amount larger than some estimates of recoverable coal reserves.””

    Even if we burned all the available carbon, including ourselves, we could not raise the atmospheric CO2 by much more than 20%. The oceans absorb CO2 at 50 to 1, a partitioning between water and air, which means we would have to burn 50 times the CO2 in the atmosphere in order to double it. The oceans are the main CO2 reservoir and we are not in control of atmospheric CO2, having no detectable effect.

    Alarmists will always tout the most extreme prediction as the likely outcome, so they can persuade the public to accept ever more damaging legislation and cuts to their rights and freedoms. Exactly the same is happening with the Covid virus scam, which may well turn out to be a bigger con than ‘climate change’.

    Does anyone know or have data on atmospheric temperatures above the Tropopause? I keep hearing alarmists claim the Thermosphere is cooling but that’s unlikely given our rate of solar irrradiance, naturally the “evidence” is hidden behind a pay wall.

      Hi CD,
      There are charts with the temperature of the stratosphere, mesosphere, and thermosphere but they are of no value. You cannot use temperature from a thermometer as an indicator of the kinetic energy in a gas. When energy is added to an unconfined gas, like the atmosphere, it expands and fewer molecules (less mass) transfer energy to the thermometer. In a gas you need to use the universal gas law to determine the kinetic energy of the gas molecules.
      The thermosphere (where heat is absorbed and radiated by the Earth) is cooling (shrinking) because it is ultraviolet and x-rays that add energy to the nitrogen and oxygen in the atmosphere, while visible light and longer wavelengths heat the solids and liquids on the Earth. UV and x-rays are produced in solar flares and with the Grand Solar Minimum there is less energy heating the atmosphere. I’ve re-written an article (The Physics of Climate Change) and submitted it which explains it further.

        Herb,
        Thanks again I remember you explaining this before to some degree (now) it makes more sense.
        I’ve had them argue with me that the “surface-lower Troposphere warming” and the rest of atmosphere “cooling” is proof of the magic GHG is working.

        I have explained solar flares reducing would contribute to that, they came back with it also contributes to the surface warming so why is it still warming?

        Knowing they are not telling the whole truth and proving it isn’t always the same thing.
