“…The former is now generally accepted as a solar event (cf. Frolov et al 2018), while the latter was likely caused by a volcanic eruption in 1458 (Sigl et al 2014(Sigl et al , 2015, with aerosol loading leading to rapid removal of beryllium in the polar region, emptying the stratospheric reservoir (Baroni et al 2011(Baroni et al , 2019. Such volcano-induced beryllium spikes can be identified in ice cores through enhanced sulphate concentration.…”

We trace the evolution of research on extreme solar and solar-terrestrial events from the 1859 Carrington event to the rapid development of the last twenty years. Our focus is on the largest observed/inferred/theoretical cases of sunspot groups, flares on the Sun and Sun-like stars, coronal mass ejections, solar proton events, and geomagnetic storms. The reviewed studies are based on modern observations, historical or long-term data including the auroral and cosmogenic radionuclide record, and Kepler observations of Sun-like stars. We compile a table of 100- and 1000-year events based on occurrence frequency distributions for the space weather phenomena listed above. Questions considered include the Sun-like nature of superflare stars and the existence of impactful but unpredictable solar "black swans" and extreme "dragon king" solar phenomena that can involve different physics from that operating in events which are merely large.

“…Büntgen et al (2018) believe the 774-775 AD event recorded as anomalies in 14 C in tree rings and as anomalous levels of 10 Be, 36 Cl and other cosmogenic radionuclides in ice cores resulted from a solar energetic particle event. Frolov et al (2018) calculate the particle fluence in the 775 AD event had to be tenshundreds times greater than in the modern powerful solar particle events in 1956 and 1972.…”

Global catastrophic risks (GCRs) affect a larger than hemispheric area and produce death tolls of many millions and/or economic losses greater than several trillion USD. Here I explore the biophysical, social-economic, demographic and cultural strands of four global catastrophic risks – sea level rise, a VEI 7 eruption, a pandemic, and a geomagnetic storm – one human-exacerbated at the least, one geological, one biological in large part, and one from space. Durations of these biophysical events range from a day or two to more than 100 years and the hazards associated range from none to numerous. Each of the risks has an average return period of no more than a few hundred years and lie within a range where many regulators ordinarily demand efforts in the case of less extreme events at enhancing resilience. Losses produced by GCRs and other natural hazards are usually assessed in terms of human mortality or dollars but many less tangible losses are at least as significant. Despite the varying durations, biophysical characteristics, and the wide array of potential consequences, the aftermath at global (and at more granular scales) can be summarised by one of four potential futures. While this assessment considers the present and the near future (the Anthropocene), much of this appraisal applies also to global catastrophic risks in the Early Holocene.
