No no, no plan, they suggested a hypothetical situation which, if it magically became true, would have an impact. As a result, they are absolved of any further effort, justification, or planning. This is the sum total of their contribution to solving global climate change. Think of them as an "ideas person," or a "visionary leader" who "manages by walking around."

After receiving this totally sufficient direction from an obviously exceptional thinker, it is entirely up to you to figure out how to make it work. If you don't, then you are not being a team player. Further criticism, or even just asking clarifying questions, is evidence YOU are the problem and are not taking constructive, solution-focused steps, and your bad attitude will be noted in your next performance review cycle along with being assigned full responsibility for letting the climate go to shit.
