mallen baker give a good summary,

Good video, well presented. The kind of common sense that isn't encouraged on this website.

But only if you dont know the relevant science or history.

The greatly varying ratios of C12/C14 in different hydrocarbon sources depending  on origin and geological history has a history going back to the 1970's and before. I remember a  big kerfuffle back in the late 1970's over the amount of radioactive aerosols and particles being emitted by British coal fired power stations. It was being blamed on the nuclear stations and they said it not  us. The oil and gas guys said its not us either. Turned out to be the coal fired stations. There were traces of thorium etc in the coal and the different  C12/C14 ratios of the emissions were a large part of tracking down the culprits. C12/C14 was the easiest marker to track as the heavy element radionuclides were very low parts per trillion.

Lots more stories like that. I remember a story of source fingerprinting of oil spill in the Gulf using the same technique. Same kind of strata, different age. Very different ratios. 

So sounds like the classic example of someone without necessary domain expertise assuming that a variable is a constant.  Nothing surprising there.  In far too many papers constants are actually variables.  The guys writing the paper make them constants so they can solve equations and draw conclusions and get the damn thing published.

Thats one of the first thing I do when I read these papers. Where are the simplifications. And how plausible  are the estimated values.  Even in the hard sciences about 80% to 90% of papers fail to pass this simple test. There still might be value in the paper but the reliability of the conclusions is knocked down a few notches.

Science is messy.

The low amount of c14 in the atmosphere's co2 content indicates that much of it is from ancient fossil sources where the c14 has already decayed, hence only an ignorant person would claim the source is not fossils.

@jmc Yes, science is messy. But too many members of this website will believe anything, so long as it fits their conviction that climate change and/or covid is some kind of con trick.

This leads to a thoroughly bizarre situation.On a site called the Daily Sceptic, the actual sceptics are those who question the dominant conspiracy agenda!

It's a nice story, of course, carbon atoms looked into fossils fuels decay to c12/13 over millions of years, hence if an excess of c14 is observed, it cannot be fossil fuels unless they  is otherwise contaminated.

In far too many papers constants are actually variables.  The guys writing the paper make them constants so they can solve equations and draw conclusions and get the damn thing published.

All models are inaccurate but some are useful.

I'm thinking about Albedo modification, since I like to have my cake AND eat it, i.e. preserve modernity while stopping climate change monomania. It would be useful to have a way to control global climate like we do with a central heating system.

Same guy lays out why it is futile to put an infinite value on data!
