At https://phys.org/news/2023-07-radiocarbon-dating-earth-environmental-glacial.html … a floating tree ring chronology has been created by using 33 larch subfossil trees from Ravine, a site located in the Venetian Prealps of NE Italy. They grew, it is thought, in the period of deglaciation – between 18,475 and 17,350 calendar years BP. Or, we might say, during the Oldest Dryas Event/Heinrich One, if I have interpeted the dates correctly. It shows greater variation in radiocarbon levels than the last calibration which is known as IntCal20 [2020]. Radiocarbon is produced when cosmic rays enter the atmosphere. It is interesting to note the variations date right at the end of the Late Glacial Maximum – so something was going on. Not only were C14 levels in flux, going up and down, but 10Be in ice cores, another radionuclide, shows variation in cosmic rays at the same time. This has been interpreted by mainstream, and the authors, as fluctuations in solar output rather than cosmic rays from beyond the solar system. Presumably this is because the Ice Ages occurred, according to current dogma, as a result of changes in solar energy brought about as the earth orbits the Sun. That doesn’t actually make sense as variations suggest the Sun was attempting to fire up to a warmer level – and was having hiccups as it did so. That might well be true but if the earth’s axis of rotation had changed at this point, variations as a result of wobble would not be out of kilter. The earth’s dipole would have entered a phase of wobble as it struggled to reach a new equilibrium – at the current position of the poles. In other words, the Late Glacial Maximum, which primarily affected NE North America and NW Europe, was due to a different location of the poles. Not too far away, of course. A point in the sea between Greenland and Baffin Island has been suggested. It was certainly a lot colder on Greenland during the LGM.
I am pointing this out as there are always other ways of looking at things. Geologists may argue the poles can’t shift yet the other day we had a post where scientists claim the poles had shifted as a result of the earthquake in the sea off the coast of Japan several years ago, and an earthquake in Chile, further back, shifted South America – by inches. Groundwater depletion as a result of irrigation and industrial processes is also thought to cause minor shifts in the poles. If poles can shift for climate science propaganda it can shift when the planet is struck by a space rock. What then might shift the poles – apart from an impact? With the discovery that the Sun is not as it was thought to be, and is an electro-magnetic animal, the possibility of pole shift is wide open for research. For example, the dinosaur asteroid seems to have shifted the poles – just look at the temperature at the North Pole at the time.
Going back to the dating issue. There are already archives, or research on the same period of time, via lake sediments, stalagmites, and marine sediments, which include the Chinese Hulu cave speleotherm. See also https://doi.org/10.1038/s43247-023-00929-9 …
