The challenges of trying to reconstruct changes in Total Solar Irradiance (TSI) since 1700: A response to Chatzistergos (2024) s remake of Hoyt & Schatten (1993) – Watts Up With That?

He seems to have created it as a parody of a TSI reconstruction. Instead, he argues that the scientific community should stick to using the SATIRE reconstructions of the MPS group or reconstructions that are similar, e.g., the NRL TSI reconstructions developed by Dr. Judith Lean at the Naval Research Laboratory (NRL) and colleagues, e.g.,…

the polarity reversal

Do terrestrial geomagnetic field reversals have an effect on Earth s climate? Cooper et al.created a precisely dated radiocarbon record around the time of the Laschamps geomagnetic reversal about 41,000 years ago from the rings of New Zealand swamp kauri trees. This record reveals a substantial increase in the carbon-14 content of the atmosphere culminating during the period of weakening magnetic field strength preceding the polarity switch. The authors modeled the consequences of this event and concluded that the geomagnetic field minimum caused substantial changes in atmospheric ozone concentration that drove synchronous global climate and environmental shifts. Geological archives record multiple reversals of Earth’s magnetic poles, but the global impacts of these events, if any, remain unclear. Uncertain radiocarbon calibration has limited investigation of the potential effects of the last major magnetic inversion, known as the Laschamps Excursion

A global environmental crisis 42,000 years ago by Alan Cooper, Chris S M Turney et al

Abstract Geological archives record multiple reversals of Earth’s magnetic poles, but the global impacts of these events, if any, remain unclear. Uncertain radiocarbon calibration has limited investigation of the potential effects of the last major magnetic inversion, known as the Laschamps Excursion [41 to 42 thousand years ago (ka)]. We use ancient New Zealand kauri trees (Agathis australis) to develop a detailed record of atmospheric radiocarbon levels across the Laschamps Excursion. We precisely characterize the geomagnetic reversal and perform global chemistry-climate modeling and detailed radiocarbon dating of paleoenvironmental records to investigate impacts. We find that geomagnetic field minima ~42 ka, in combination with Grand Solar Minima, caused substantial changes in atmospheric ozone concentration and circulation, driving synchronous global climate shifts that caused major environmental changes, extinction events, and transformations in the archaeological record.
