No Place to Hide? Regional Resilience and Vulnerability to Global Catastrophic Risk
Global Challenges, Volume 10, Issue 8, August 2026.No location on Earth withstands every global catastrophe. This review maps the geographic, institutional and infrastructural factors shaping resilience to nuclear, volcanic and impact winters, infrastructure loss and pandemics. Geographic isolation, food self‐sufficiency, strong governance and decentralization improve resilience across scenarios ...

PFN report on field meteorite search in period 2018–2020 [PDF]
, 2021 Since 2010, the Meteorite Section of the Comet and Meteor Workshop (PKiM) has been systematically organizing exploratory expeditions to selected meteorite strewn fields, calculated from bolides registered with the Polish Fireball Network (PFN).

Comparing Monte Carlo Models of Impact Alteration of Planetary Atmospheres
Journal of Geophysical Research: Planets, Volume 131, Issue 8, August 2026.Abstract One process that affects atmospheric surface pressure is impact bombardment. The evolution of a planet's atmosphere under impact bombardment is an open question. We use a Monte Carlo method to evolve a range (0.006–92.5 bar) of initial atmospheres at Mars, Earth, and Venus under bombardment of 5×106 $5\times 1{0}^{6}$ impactors using seven ...

GOES GLM, Biased Bolides, and Debiased Distributions
, 2023 The large combined field of view of the Geostationary Lightning Mapper (GLM) instruments onboard the GOES weather satellites makes them useful for studying the population of other atmospheric phenomena, such as bolides.

Catastrophic bolide impacts on the Earth: Some estimates [PDF]
, 2006 We analyze the impact of large high velocity bodies on the surface of the Earth and obtain estimates of the size of the crater. We show that the atmosphere does not stop large bolides and their mass loss and heating during entry in the atmosphere can be ...

Possible test of ancient dense Martian atmosphere [PDF]
, 1993 We have completed preliminary calculations of the minimum sizes of bolides that would penetrate various hypothetical Martian atmospheres with surface pressures ranging from 6 to 1000 mbar for projectiles of various strengths.

The Astronomical JournalHow effective are methods for estimating bolide energies from infrasound signal period-yield relationships? A single global period–energy relation can obscure significant variability introduced by parameters such as the atmospheric Doppler wind profile ...
