Imagine 8 billion people, running the equivalent of 20,000 coal power plants, switching to zero-GHG-emissions sources of energy overnight, for all future. Greta would say: magical dreams of infinite growth. If this is “best available science,” we need better science. smh https://twitter.com/_ppmv/status/1358447578241773574
This doesn’t matter. But it’s emblematic for the state of climate, where random assumptions & out-of-this-world wishful thinking pass for serious argument
Between a Nobel prize for “4°C are the optimal, never mind they would end humanity” Nordhaus, & bulldozer Michael Mann as the most prominent spokesman for climate, I remain unconvinced we’re remotely up to speed on climate. Surely we’d find better people if we were?
Worth persisting on supporting climate efforts for some time. But color me unimpressed with the quality of analysis I’ve seen, or the resources devoted to humanity’s most important question. Understandable in an egotistic world, but hard to imagine that this is the best we can do
Why this matters: as David says 👇, Mann & certain other climate scientists in recent years started *confidently* promoting scenarios like “zero GHG by 2050,” when their social science assumptions strike me as weak & barely even consciously reflected. Way to wager a civilization https://twitter.com/davidlwindt/status/1358464825282682880
