The Joke

Scientists detect an asteroid heading toward Earth. They announce the threat and propose solutions. Instead of uniting to address the existential threat, humanity immediately begins arguing about who should pay for the defense, whether the asteroid is really a threat, whether the scientists have a political agenda, and whether asteroids are mentioned in religious texts. The asteroid hits.

The Humor

This is a thinly veiled allegory for climate change (or any long-term existential risk). The comic's point is that even when facing a clear, evidence-based threat with known solutions, human political systems are incapable of mounting a coordinated response because the incentive structures reward short-term thinking, denialism, and free-riding.

The asteroid makes the allegory sharper than climate change because the threat is more immediate and less ambiguous — and humans still can't get it together. If we can't coordinate against a visible asteroid, what hope is there for invisible greenhouse gases?

Context

This comic is frequently shared in discussions about existential risk, particularly in the rationalist and effective altruist communities. It illustrates the concept of "civilizational inadequacy" — the idea that human institutions are systematically unable to address certain classes of problems.
