A Simple Question for Alarmists

What physical evidence supports the contention that carbon dioxide emissions from burning fossil fuels are the principal cause of global warming since 1970?

(Remember back in the 1970s, climate scientists and media were predicting a return to an “ice age.”)

I have posed that question to five “climate scientist” professors at the University of Arizona who claim that our carbon dioxide emissions are the principal cause of dangerous global warming. Yet, when asked the question, none could cite any supporting physical evidence.

Some of the professors would claim that computer models, when corrected for natural variation, required carbon dioxide emissions to correlate with observed warming of the late 20th century. But computer modeling is not physical evidence; it is mere speculation. And correlation does not prove causation.

One could easily substitute any increasing time series of data to produce similar results. In fact, an Australian group did a tongue-in-cheek exercise of comparing the historical price rise of a first class U.S. postage stamp with temperature. Results are shown in the graph below. The rise in the price of a stamp shows a remarkable correlation with the rise in global temperature.

In seeking an answer to the initial question, I also read the many reports from the UN Intergovernmental Panel on Climate Change. The reports provide no physical evidence, only various scenarios generated by computers. The outputs from computer models diverge widely from observational evidence because the models attribute too much warming influence to carbon dioxide emissions and little to none to natural variation. (See Why Climate Models Run Hot by Rud Istvan.)

It appears that there is no physical evidence showing that carbon dioxide emissions have a significant effect on global temperature. There is, however, physical evidence showing that our carbon dioxide emissions are not having any significant effect, see my article Evidence that CO2 emissions do not intensify the greenhouse effect for details. That article examines four predictions made by climate alarmists of what we should see as atmospheric carbon dioxide content rises. In each case, what really happened was the opposite of what was predicted.

The benighted, eco-faddish, Tucson City council wants to reduce the City’s carbon footprint by installing 100 percent renewable energy for all city government operations so Tucson will not get as hot as Phoenix. (Source) If they do that, they really will be in the dark. In another article, Impact of Paris climate accord and why Trump was right to dump it, I present research which shows that even if all countries fulfilled their pledges to reduce carbon dioxide emissions made in the Paris Climate Accord, it would make a difference of only 0.17°C by the year 2100.

Can anyone provide an answer to the initial question?

One other complication, Fake warming: A new peer-reviewed study finds that nearly all reported warming in the 20th century is a result of historical adjustments made to the original data. The study concludes: “The conclusive findings of this research are that the three GAST data sets [ Global Average Surface Temperature (GAST) data, produced by NOAA, NASA, and HADLEY] are not a valid representation of reality.

In fact, the magnitude of their historical data adjustments, that removed their cyclical temperature patterns, are totally inconsistent with published and credible U.S. and other temperature data. Thus, it is impossible to conclude from the three published GAST data sets that recent years have been the warmest ever –despite current claims of record setting warming.” Read the study

Bottom line: Reducing carbon dioxide emissions will have little to any effect on global temperature. Such efforts are therefore a waste of money and other resources.

      Always
      Spurning Plover, once again spew vile ignorance at people FAR Smarter
      than he could EVER be.

      Scientists WERE ALREADY LECTURING ABOUT GLOBAL WARMING and the resulting Climate Changes, in 1847 !
      .
      “The heat-trapping nature of carbon dioxide & other gases was experimentally demonstrated & PROVED in the mid-19th century.”
      ..( these same fundamental experiments are Challenged & REPEATED Every year, in nearly every University , around the world !
      .
      …they have been put up for study, & critique !

      … for decades, no appreciable critique of the fundamental science of Global Warming
      …not in climatology,
      not in physics,
      not Earth Science,
      not physical science,
      not in Meteorology, etc.

      ( Instead of 225-285PPM, as it has been for 1,000’s upon 1,000’s of years, today CO2 is NOW   ‘OVER’   411PPM ! )
      Humans have never existed during a time when CO2 or Methane have been this HIGH.
      We have no IDEA what this experiment with HIGHER Atmospheric Gases may have on Humans or life itself.

      ( Humans are NOW emitting more than 135 TIMES as much CO2 as ALL of the volcanoes on EARTH, each & every year, COMBINED ! )
      (The Unique Isotopic Signature proves that this CO2 INCREASE is from Human Activities & the Burning of Fossil Fuels)
      .
      CO2 traps heat
      .
      According to radiative physics & decades of laboratory measurements, increased CO2 in the atmosphere is expected to absorb more infrared radiation as it escapes back out to space.

      In 1970, NASA launched the IRIS satellite measuring infrared spectra.
      In 1996, the Japanese Space Agency launched the IMG satellite which recorded similar observations.
      Both sets of data were compared to discern any changes in outgoing I.R. energy radiation over the 26 year period .
      .

      published in respected Science Journals & the science has been repeatedly been Replicated.
      .
      What they found was a drop in outgoing radiation at the wavelength bands that greenhouse gases such as CO2 and methane (CH4) absorb energy.
      .
      The reductions in outgoing radiation was consistent with Global Warming theoretical expectations.

      ** Thus these research studies & papers  found:

      (  If Infra Red HEAT Energy, does not escape, it is retained in our Earth System as rising temperatures, warming seas, & melting Ice. )

      These results has been confirmed by subsequent Studies & Research papers using data from later satellites.

      When greenhouse gases absorb infrared radiation, the energy heats the atmosphere which in turn re-radiates infrared radiation in all directions.
      .
      Much of it makes its way back to the earth’s lower atmosphere.
      .
      Hence we expect to find more infrared radiation heading downwards.
      .
      Surface measurements from 1973 to 2008 find an increasing trend of infrared radiation returning to earth.

      The planet IS accumulating heat

      CO2 does have some benefits, like stimulating plant growth under certain conditions….but also depletes Nutrients in Staple Grains…less iron, …less protein,… less Zinc.

      CO2 causes dizziness, fainting, nausea, & KILLS.
      Every Large building on Earth HAD to install air circulation systems to prevent these effects….the higher CO2 levels in our atmosphere
      …the more these units need to be upgraded.
      CO2 is heavier than AIR, it accumulates in basements, sealed rooms, protected glades.
      **
      “Miners not only walked into deadly accumulations of (CO2) choke damp; they were also sometimes lowered into them by being let
      down into mine shafts on ropes.
      If they hit pockets of carbon dioxide during their descents, they would fall from those ropes dead.”
      **
      “Persons not employed in the coal mining trade are unlikely to encounter deadly masses of carbon dioxide,
      yet such clouds have been known to form in the open air and at a cost dear in human life. Which was indeed the case on
      21 August 1986 at Lake Nyos in Cameroon.” 1746 DEAD.

      “The deadly cloud covered an area of up to 12 miles
      around the lake, killing thousands of cattle as well.

      A similar incident in 1984 at Lake Monoun, another crater lake in western Cameroon, killed 37 people.”

      Ocean acidification’s other evil twin – Blood acidification.

      Going from 250 to 410 ppm CO2 we’ve increased the pH of our blood by 0.1
      (equivalent to an increase in acidity of 30%).

        Except – you’re ignoring the fact that the effect is not linear http://theclimatescepticsparty.blogspot.com/2015/02/the-logarithmic-effect-of-carbon-dioxide_19.html
        Atmospheric levels of CO2 aren’t toxic. The Obama administration, in its desire to sequester CO2 however, would have created the possibility of a Lake Nyos catastrophe.
        Atmospheric CO2 will never reach toxic levels because “The ocean can handle all the carbon that is left for humanity to burn. There is enough calcium in the upper 200meters of the ocean to combine with all CO2 that you can burn from what we call the null reserves of fossil fuel” – Dr. Tom Segalstad

        Btw, they allow up to 8,000ppm in submarines with no harmful effects.

        You wrote that co2 retain heat. Strange thing: google thermal insulation and you will find that to retain heat, you must PREVENT ABSPORPTION in the cold surroundings to “retain heat”. Just click on the wiki-article for thermal insulation. It is in the introduction.

        Maybe you should try physics instead of the greenhouse mosque.

        The atmosphere is an added heat sink on top of space, not an interfering one. Why would anyone think that cold fluid heats hot surfaces, that is stupid.

        Oh, yeah, you are religious, that’s why.

        You should seriously consider studying biology. This is among the mist stupid things I’ve ever read.

        Rakool: Can you point to ANY climate prediction which has come true.
        As of this minute I am willing to meet with you, exchange identification and draw up a legal and binding agreement for a wager of $50,000 AUD that the Arctic Sea Ice will not disappear in the summer of 2017/18.

    I really like the idea that U.S. postal charges drive climate change. The correlation is pretty outstanding 😉
