THIS POST IS A COLLECTION OF LINKS TO RELATED POSTS ON THIS SITE THAT TOGETHER EXAMINE THE STATISTICAL VALIDITY OF THE CLAIM BY CLIMATE SCIENCE THAT ANTHROPOGENIC GLOBAL WARMING IS CAUSED BY FOSSIL FUEL EMISSIONS BECAUSE THESE EMISSIONS CHANGE ATMOSPHERIC COMPOSITION. 

 

A WUWT POST: “But the idea that the Worldwide Covid Lockdown has had any effect on atmospheric CO2 concentrations is simply not true. And that’s the news for the day…. Don’t ask me to explain it, I don’t know. But it sure is interesting – even I thought the lockdowns would show up at Mauna Loa.” [LINK]

RESPONSE: There are a few things to consider when relating observed changes in atmospheric composition to fossil fuel emissions (if fossils they are) as explained in the documents linked below.

 

LINK#1: When the stated uncertainties in carbon cycle flows are not considered we can detect fossil fuel emissions in the mix and measure its effect on atmospheric CO2, but when the stated uncertainties in carbon cycle flows ARE considered the relatively small flow of fossil fuel emissions cannot be detected. Bottom line: from a purely empirical point of view we can’t even tell that fossil fuel emissions exist let alone measure their effect on the atmosphere.   [CLICK HERE FOR LINK#1]

 

LINK#2: “Since the industrial revolution we have been burning fossil fuels and at the same time atmospheric CO2 has been going up.” This kind of logic has no causation interpretation as Tyler Vigen has shown over and over and over again.                     [CLICK HERE FOR LINK#2]

 

LINK#3: To keep Tyler happy, what we need to do is to compute the detrended correlation between fossil fuel emissions and atmospheric composition at an annual time scale. Why annual time scale? Because the IPCC and the Carbon Project and climate science in general carry out this mass balance at an annual time scale. I looked for that detrended correlation. It’s not there. Here is my work. [CLICK HERE FOR LINK#3]

 

LINK#4: Climate science has an answer to that and it is the Damon Matthews 2009 paper. Damon says screw the atmospheric composition thing because there is a near perfect correlation between cumulative warming and cumulative fossil fuel emissions. The regression coefficient of that relationship shows that temperature goes up by about 1.5C per terratonne of cumulative emissions give or take 0.5C. Climate science now says that this coefficient, that Damon calls the Transient Climate Response to Cumulative Emissions (TCRE), is the proof of human cause and the measure of the impact of emissions on temperature and also the tool we need to construct climate action plans with carbon budgets. [CLICK HERE FOR LINK#4]

 

LINK#5: Sadly for Damon and for climate science, Damon made a horrible statistics error in his TCRE proposal. It is described in detail here [CLICK HERE FOR LINK#5]

 

LINK#6: When Damon’s statistics error is corrected we find no evidence that warming is related to fossil fuel emissions and no evidence that the rate of warming can be attenuated by reducing fossil fuel emissions in accordance with the “climate action” demands of climate science and the United Nations [CLICK HERE FOR LINK#6]

 

LINK#7: For those not easily convinced by boring statistics arguments, here is a demonstration of the spuriousness of correlations between cumulative values.

If I had one wish, it would be to have people know the difference between correlation and causation.

Yes sir. A complex issue not well understood in climate science. Thank you for this reminder.
