Causation Of Climate Change, And The Scientific Method — Manhattan Contrarian
I've spent a lot of time and energy debunking Global Climate Hysteria. Unfortunately, cults are impervious to facts, reason, and logic. Update on the Holocene and how it undermines climate fear mongering Men go mad in mass, but only regain their senses slowly one by one. (Thanks to Mackay in Extraordinary Popular Delusions and the Madness of Crowds (Harriman Definitive Edition): The Classic Guide to Crowd Psychology, Financial Folly and Surprising Superstition for the paraquote). We are in for the long haul.
Evaluate the following three graphs after you read the article quoted below then tell me if you see any indication of correlation whatsoever. I do not. That is what makes the entire AGW hysteria so unbelievable. There is a period of less than 20 years ( 1978 - 1996 or perhaps 1998.) where the climate correlates with the AGW hysterics theory. That's all folks. There are not millennia, or centuries, not even decades, only a period of less than 20 years.
What bothered me most when I first became aware of AGW theory was that it lacked any significant amount of evidence. I expected to see thousands of years of data and a bright line shift in the data which established a clear correlation, and then clear bright line experimentation establishing that the AGW theory unambiguously beat the "placebo." Nope. That never happened. Instead, I saw defrauded data, lousy data, research findings that did not provide necessary data to evaluate the research findings and much worse. I also found hundreds if not thousands of emails of the AGW hysterics/charlatans plotting their lies. The whole sordid mess is a travesty and in the US, felonious since these people are defrauding the federal taxpayers.
Marcott et al. is the only worldwide proxy reconstruction of the Holocene to date. It should be used as the primary data source when discussing the world Holocene climate. Notice how the climate was far warmer 10,000 - 3,000 years ago. What is most remarkable about his data set is that it refutes AGW hysteria nearly completely. Notice the myriad temperature declines in the graph and understand that all of them resulted in a rebound. Why is the Curren rebound from the deepest, coldest decline during the Holocene surprising? It is not.
To compound matters CO2 rises in the graph while global temperatures fall, all before humans had any effect on climate. But notice how the modeled temperatures (green line on graph) seem to closely correlate to the rise in CO2. This is BS following the BS AGW theory, not reality.
How cold is it today compared to the entirety of the Holocene? Cold. Pretty much colder than at any other time during the Holocene save for three other even colder periods
Yes, the ice age was colder, but the Holocene was nearly always warmer than today. The data does not fit the hysterics.
So, what happens if we go back 600 million years, the AGW smoking gun must be in that data, right? Nope.
So, we are in the coldest period and the lowest CO2 levels of the past 600 million years. We are not in a high carbon/CO2 period; we are in a CO2 drought. The problem is not too much CO2 but too little in the atmosphere. Life on Earth flourished 600-500 million years ago with the most dynamic bloom of life in Earth's history. Yet the AGW hysterics claim the problem today is too much carbon, not too little. The data does not support their position. We live in an ice age; yes, we live in a temporary interglacial warming period during the ice age, but we live in an ice age, and the reason is there is too little carbon in the atmosphere to drive life. We live in the dying days of life on Earth, all the while the AGW hysterics claim the opposite, carbon is a toxic poison, not a necessary building block for life.
Notice that Earth's temperature during the past 600 million years was generally near 22˚C; it is now near 12˚C, a 10˚ decline. Also, note the fact that CO2 is the lowest it has been excepting two other brief periods.
CO2 and temperature are not correlated in these graphs, only in the minds of the AGW hysterics.
Also, note that CO2 begins to gradually decline from the great bloom of life about 550 million years ago and continues right up to the present.
So, why is CO2 so low now?
The answer is simple. Animal life uses carbon to create durable structures like bones and shells. Over millions of years, those carbon structures became embedded in the sedimentary rock, which sequestered them away from the atmosphere and away from existing life. 600 million years ago, carbon was free in the oceans and atmosphere, and life could freely use that carbon. Yet the Earth did not burn up because that theory is silly BS. Over millions of years, the Earth's carbon has been bound in rock and unavailable to life. The situation is dire. We are very near the point at which life cannot continue if atmospheric CO2 declines much further.
Life on Earth was nearly doomed by too little CO2
I stand in awe that the anti-science progressive cult has so completely propagandized the academe and the people that many actually believe in the cult's lies.
I have hundreds of articles on AGW and the lies and fraud the hysterics perpetrate.
Below I repost the contents of the original article. Please click through and give the article a read at Manhattan's site; he deserves your click.
"Let’s have yet another go at trying to apply the scientific method to the subject of causation of climate change. This is just basic logic, and not that complicated. We can do it.
As simple and basic as this is, you will shortly see that the agglomeration of all of the world’s leading “climate scientists” can’t figure it out. They are completely lost and befuddled. Check me and see if I’m wrong.
The proposition we are addressing is the one for which you see a constant drumbeat of advocacy. It runs something like, “the climate is changing, and we are the cause.” OK, nobody denies that the climate is changing; but how about the “we are the cause” part? What is the proof?
Let’s apply the scientific method. We start with the basic maxim that “correlation does not prove causation.” Instead, causation is established by disproof of all relevant alternative (“null”) hypotheses.
Everybody knows how this works from drug testing. We can’t prove that drug A cures disease X by administering drug A a thousand times and observing that disease X almost always goes away. Disease X might have gone away for other reasons, or on its own. Even if we administer drug A a million times, and disease X almost always goes away, we have only proved correlation, not causation. To prove causation, we must disprove the null hypothesis by testing drug A against a placebo. The placebo represents the null hypothesis that something else (call it “natural factors”) is curing disease X. When drug A is significantly more effective at curing disease X than the placebo, then we have disproved the null hypothesis, and established, at least provisionally, the effectiveness of drug A.
Back to climate change. The hypothesis is “humans are causing significant climate change.” An appropriate null hypothesis would be “observed climate change can be fully explained by some combination of natural factors.” How might you test this?
The most obvious test would be to ask, in earth’s recent history, has it been warmer than the present — the present having been the subject of significant human greenhouse gas emissions? If periods in the recent past prior to human emissions have been warmer than the present, then quite obviously some combination of “natural factors” is sufficient to bring about temperatures as warm or warmer than we are experiencing.
And it doesn’t matter whether or not we know what the alternative “natural factors” might be, any more than, in the failed drug trial, it matters whether or not we know why the placebo beat the experimental drug. In the failed drug trial, it could have been the human immune system, or it could have been gut bacteria, or it could have been the weather, or anything else. The fact is that, whatever they might have been, the “natural factors” outperformed the experimental drug.
For the test of the climate hypothesis, consider a December 28 blog post from retired physicist Ralph Alexander titled “New Evidence That Ancient Climate Was Warmer Than Today’s.” Alexander summarizes the results of two recent studies:
A June 2020 piece from Nature titled “Persistent warm Mediterranean surface waters during the Roman period,” by a group of Italian and Spanish authors led by G. Margaritelli.
A November 2020 piece from New Scientist titled “Climate change has revealed a huge haul of ancient arrows in Norway,” by C. Baraniuk.
The Margaritelli, et al., piece analyzes proxy data from “fossilized amoeba skeletons found in seabed sediments” to reconstruct Mediterranean Sea temperatures over the past 2000 years. “The ratio of magnesium to calcium in the skeletons is a measure of the seawater temperature at the time the sediment was deposited; a timeline can be established by radiocarbon dating.” Conclusion:
With the exception of the Aegean data, the results all show distinct warming during the Roman period from 0 CE to 500 CE, when temperatures were about 2 degrees Celsius (3.6 degrees Fahrenheit) higher than the average for Sicily and western Mediterranean regions in later centuries, and much higher than present-day Sicilian temperatures.
The Baraniuk study, from Norway, analyzes large new finds of ancient artifacts, including arrows, arrowheads, and clothing, that have been revealed by recent retreats of glaciers in that country. But of course, the existence of the artifacts in these areas implies that the areas were not covered in ice at the time the artifacts were deposited:
That the artifacts come from several different periods separated by hundreds or thousands of years implies that the ice and snow in the region must have expanded and receded several times over the past 6,000 years. During the Holocene Thermal Maximum, which occurred from approximately 10,000 to 6,000 years ago and preceded the period of the stunning Norwegian discoveries, global temperatures were higher yet. In upper latitudes, where the most reliable proxies are found, it was an estimated 2-3 degrees Celsius (3.6-5.4 degrees Fahrenheit) warmer than at present.
Whether 2000 years ago (the Roman Warm Period) or 6000 years ago (the Holocene Thermal Maximum), these periods clearly long preceded any significant human greenhouse gas emissions from the burning of fossil fuels. Obviously, then, some combination of “natural factors,” whatever they may be, is sufficient to cause terrestrial temperatures to increase to levels as high or higher than we are experiencing today, in the era of human use of fossil fuels.
I should mention that the two papers discussed by Alexander are just the latest of many dozens of studies giving evidence for the proposition that times in the recent geologic past — either the Medieval Warm period, or the Roman Warm Period, or the Holocene Thermal Maximum — were warmer than today. One collection of many papers, mostly focusing on the Medieval Warm Period, can be found at Craig Idso’s CO2 Science website.
You would think that mainstream climate “science” would be focused like a laser beam on trying to deal with these early periods that were warmer than today. But instead, these guys have almost entirely taken a different approach. They call their approach “detection and attribution.” Of many examples of the art, here is a major paper from 2018, sponsored by the UN’s Intergovernmental Panel on Climate Change, with the title “Detection of Climate Change and Attribution of Causes.” The authors are a who’s who of the official climate establishment, including the likes of Phil Jones, Michael Mann, Gerald North, Gabriele Hegerl, and Ben Santer.
Instead of evaluating whether available data refute either their main hypothesis (human causes) or the null hypothesis (natural factors), these guys adopt a different approach which I would describe as “we can’t think of anything else other than human greenhouse gas emissions that could be causing this, so therefore human emissions it is.” They create so-called models of what they think natural factors might cause in the way of warming, and then test those against the data. Since when does that prove anything? The article is very long and riddled with nearly impenetrable jargon that makes it near impossible to get a good quote, but here are a couple of the best:
Attribution studies have applied multi-signal techniques to address whether or not the magnitude of the observed response to a particular forcing agent is consistent with the modelled response and separable from the influence of other forcing agents. The inclusion of time-dependent signals has helped to distinguish between natural and anthropogenic forcing agents. As more response patterns are included, the problem of degeneracy (different combinations of patterns yielding near identical fits to the observations) inevitably arises. Nevertheless, even with the responses to all the major forcing factors included in the analysis, a distinct greenhouse gas signal remains detectable. Overall, the magnitude of the model-simulated temperature response to greenhouse gases is found to be consistent with the observed greenhouse response on the scales considered.
And here’s another:
To detect the response to anthropogenic or natural climate forcing in observations, we require estimates of the expected space-time pattern of the response. The influences of natural and anthro- pogenic forcing on the observed climate can be separated only if the spatial and temporal variation of each component is known. These patterns cannot be determined from the observed instru- mental record because variations due to different external forcings are superimposed on each other and on internal climate variations. Hence climate models are usually used to estimate the contribution from each factor.
Apparently, this kind of mumbo jumbo is good enough to fool pretty much all of academia, and most all journalists, not to mention gaggles of billionaires. But how about the Medieval Warm Period and the Roman Warm Period? Don’t those refute the whole thing?"
