[LINK] Neil deGrasse Tyson on killer asteroids

LessWrong is not big on discussion of non-AI existential risks. But Neil deGrasse Tyson notes killer asteroids not just as a generic problem, but as a specific one, naming Apophis as an imminent hazard.

So treat this as your exercise for today: what are the numbers, what is the risk, what are the costs, what actions are appropriate? Assume your answers need to work in the context of a society that’s responded to the notion of anthropogenic climate change with almost nothing but blue vs. green politics.
