Visionaries and Crackpots, Maniacs and Saints: Existential Risk and the Politics of Longtermism

Ratio, Volume 38, Issue 4, Page 268-278, December 2025.
ABSTRACT Despite advancing strong claims about our collective priorities, longtermism has received little attention in debates in political philosophy. I first provide an account of longtermism that highlights the way it departs from established work on intergenerational justice.

Quantification of Perturbation to the Daytime Lower Ionosphere From a Gamma Ray Burst Using ELF Remote Sensing

Geophysical Research Letters, Volume 52, Issue 22, 28 November 2025.
Abstract On 9 October 2022, a powerful gamma ray burst (GRB), GRB221009A, caused significant changes in the electron density of the lower ionosphere, as evidenced by VLF (3–30 kHz) radio wave observations. However, GRB221009A did not yield any observable signatures at the Schumann resonances (∼8, ∼14 Hz), which are also sensitive to the lower ...
