California full-ring sequoia (Eastoe 2019): radiocarbon rise between the 1052 and 1053 rings
Annual sequoia series AD 998 to 1510 measured at Arizona. Brehm et al. 2021 and Panyushkina et al. 2022 both describe its 1052 to 1053 rise as matching the English oak STK-C10. A third tree with first high ring 1053, on a different continent. The exact values are behind a paywall and have not been read here.
How it connects
This clue from nature supports this hunch
The 1052 white vapour matches the 1052 radiocarbon candidate first high ring 1053
