My new map about asteroids and impact risks is up!
This map is part of the “Map of Natural Risks ” which is in turn part of the map “Typology of Global Risks.”
TL;DR: Observation is the best instrument in asteroid risk reduction, and large nuclear anti-asteroid defense could be more of a threat to Earth and be of negative
value; but the main uncertainty is whether we live in a period of intense bombardment because of recent large comet break-up.
