Abstract Numerous studies over the past 30 years have suggested there is a causal connection between the motion of the Sun through the Galaxy and terrestrial mass extinctions or climate change. Proposed mechanisms include comet impacts (via perturbation of the Oort cloud), cosmic rays and supernovae, the effects of which are modulated by the passage of the Sun through the Galactic midplane or spiral arms. Supposed periodicities in the fossil record, impact cratering dates or climate proxies… 
Evidence for a variation - but no periodicity - in the terrestrial impact cratering rate
Giant impacts by comets and asteroids have probably had an important influence on terrestrial biological evolution. There are about 180 confirmed high velocity impact craters on the Earth with ages
Exploring the role of the Sun's motion in terrestrial comet impacts
The cratering record on the Earth and Moon shows that our planet has been exposed to high velocity impacts for much or all of its existence. Some of these craters were produced by the impact of long

Abstract Despite tremendous interest in the topic and decades of research, the origins of the major losses of biodiversity in the history of life on Earth remain elusive. A variety of possible causes
Disc dark matter in the Galaxy and potential cycles of extraterrestrial impacts, mass extinctions and geological events
A cycle in the range of 26–30Myr has been reported in mass extinctions, and terrestrial impact cratering may exhibit a similar cycle of 31 ± 5Myr. These cycles have been attributed to the Sun’s
Risks for life on habitable planets from superflares of their host stars
We explore some of the ramifications arising from superflares on the evolutionary history of Earth, other planets in the Solar system, and exoplanets. We propose that the most powerful superflares
Potential encoding of coupling between Milankovitch forcing and Earth's interior processes in the Phanerozoic eustatic sea-level record
Abstract The driving mechanisms of Earth's climate system at a multi-Myr timescale have received considerable attention since the 1980's as they are deemed to control large-amplitude climatic
Biological implications of high-energy cosmic ray induced muon flux in the extragalactic shock model
TLDR
The biological dose resulting from enhanced muon exposure from cosmic rays and their implications for terrestrial biodiversity variations are computed using the Monte Carlo simulation package CORSIKA.
A model of possible variations of the galactic cosmic ray intensity over the recent billion years
Based on the analysis of published data on exposure ages of iron meteorites determined with the 40K/K method (TK) and ages calculated using short-lived cosmogenic radionuclides (with the half-life
Periodic Signals of the Milky Way Concealed in Terrestrial Sedimentary Basin Fills and in Planetary Magmatism
Long periodic geodynamic processes with durations between 150 and 600 Million years appear to be in phase with similar galactic cycles, caused by the path of the solar system through the spiral arms
Clouds and the Faint Young Sun Paradox
Abstract. We investigate the role which clouds could play in resolving the Faint Young Sun Paradox (FYSP). Lower solar luminosity in the past means that less energy was absorbed on Earth (a forcing

TLDR
The first priority in any plan for defense against impactors is to survey the population of Earth-crossing NEAs and project their orbits forward in time, and the purpose of the Spaceguard Survey, which has already found more than half of the NEAs >1 km in diameter.

Abstract Recent suggestions of periodic cometary showers coincident with mass extinctions have prompted a review of the terrestrial cratering record. From the point of view of completeness of search
