Crisis envy

If we can shut down the world to stop a virus, how come the public won't accept plans to cripple the global economy in service of climate alarmism? I'm just spitballing here, but it's possible a lot of people genuinely believe in the danger of a contagious, sometimes fatal disease, and aren't just virtue-signaling about a trendy hypothetical threat. Even in the case of the virus, there are those inconvenient people who insist on continually checking our assumptions against facts on the ground, kvetching about shoddy models, and thinking about cost-benefit trade-offs.
