Its perfectly actionable. Its just inconvenient. Imagine if tomorrow we discovered that internal combustion engines produced a gas which immediately killed everyone with 200 feet. What would change?
My point is that it’s theoretically “actionable”, but like all collective action problems (this being perhaps the most challenging example, because the scope is global, the timeline is decades to centuries, and the economic incentives are misaligned with taking action), it’s very difficult for an actual person to take any meaningful action. So pragmatically speaking, it’s not really actionable. Which is why I basically think we’re fucked in the short-term, and will really just be saved by cheap renewables changing the incentives, as they have been. We’re not going to magically solve the most intractable collective action problem of all time.
