"Is climate anxiety to be a permanent imposition?"

Excerpt from this post:

Without a standard advent, or indeed a comprehensive and observable meaning, it is impossible to answer if or when global warming as a physical phenomenon will ever have ended, but the question does lead to the more relevant problem of whether global warming as a political and rhetorical implement has a perceptible best-before date. How many years of ordinary survival and non-cataclysm, for example, would it take before politicians and activists might possibly abandon years of countless trade restrictions, caps and bans, artificial market schemes, conferences, advertising and general alarms as just so much fruitless agony and opportunism, not to mention untold billions of dollars of wasted wealth. Or is climate anxiety to be a permanent imposition?
