Well, first, I read a very different conclusion from the paper... They say, for example: "That realization prompted us to reconsider the economics of energy. What’s needed, we concluded, are reliable zero-carbon energy sources so cheap that the operators of power plants and industrial facilities alike have an economic rationale for switching over soon—say, within the next 40 years." In other words, it's absolutely an economics question. It's also a policy question: Subsidies and penalties can radically change the economic realities for power plant operators. They're saying it's a very hard road. But notably, their graphs are not delta functions: There's paths between the best case and worst case scenarios, and excellent progress on the renewables front can, indeed, change the direction of the curve. Pulling carbon back to pre-industrial levels absolutely requires active sequestration, though, and there are efforts on that front, though the second law of thermodynamics tells us it's a hard road. But again, some progress is better than none. Your last 'graf sounds like unmitigated tinfoilhat-ism, I'm sorry to say. We should absolutely expect fluctuations in co2 measurements based on geography and proximity to large volumes of co2-spewing vehicles. There are standards for the calculation of average co2 ppm, which are helpful for knowing the overall state of things, and trends over time.

That is not the conclusion. They set out to prove that renewables was the way. They discovered they were wrong. That is a paradigm-shattering conclusion. To this day we hear incessant talk about renewables "saving the planet". This is nonsense. The only problem I have with the paper is that they did not follow this conclusion with a real study of the plausibility of any solution on a human time scale. They say things like having to capture carbon and have better power plants in 40 years. None of it is correlated to actual realizable effects at scale. > Your last 'graf sounds like unmitigated tinfoilhat-ism That isn't MY graphic! That's from the 800,000 ice core atmospheric sample data. Here: https://cdiac.ess-dive.lbl.gov/trends/co2/ice_core_co2.html https://cdiac.ess-dive.lbl.gov/trends/co2/ice_core_co2.html It's the first link in the "Graphics" section. If you are going to all this tin-foil it means negating all science on the subject. This data is incredibly accurate and reliable. One of my first questions when finding this data set was the simplest of inquiries: Can ice core atmospheric data from 800,000 years ago be accurate? Well, it turns out, yes, it is. I found and read papers on the subject. It's fascinating technology actually. The statement I made was that solar and wind --renewables-- can't help us and are pretty much an empty pursuit as it pertains to "saving the planet". These researchers went into it CONVINCED renewables was the way and conducted this research to, as they said, once and for all show the world. What they discovered is they were as wrong as one could be. Renewables are a waste of time, money and resources. They are good and very much justified for other reasons, just not anything related to climate change or atmospheric CO2 concentration. As I said, I have a 13 kW solar array, soon to grow to 20 kW. I am under no delusion about what it is for. It serves no purpose whatsoever as it pertains to climate change. This is particularly true if you consider the entire installation, which includes a large ground-mounted structure, concrete footings, etc. I sometimes wonder how much carbon was produced to go from minerals on the ground to a structure on my property with a theoretical 13 kW peak generation capacity. Different subject.
