Solar irradiance changes and photobiological effects at Earth's surface following astrophysical ionizing radiation events
Brian C. Thomas, Patrick J. Neale, Brock R. Snyder
Astrophysical ionizing radiation events have been recognized as a potential threat to life on Earth, primarily through depletion of stratospheric ozone and subsequent increase in s…
Terrestrial effects of possible astrophysical sources of an AD 774-775 increase in 14C production
Brian C. Thomas, Adrian L. Melott, Keith R. Arkenberg +1
We examine possible sources of a substantial increase in tree ring 14C measurements for the years AD 774-775. Contrary to claims regarding a coronal mass ejection (CME), the requir…
Revisiting the Carrington Event: Updated modeling of atmospheric effects
Brian C. Thomas, Keith R. Arkenberg, Brock R. Snyder
The terrestrial effects of major solar events such as the Carrington white-light flare and subsequent geomagnetic storm of August-September 1859 are of considerable interest, espec…
