> Making progress in (subtask of A) means we are making progress in (A). Not always, but I will grant that it likely does in the case of emissions reduction. (consider a thought experiment - US reduces emissions from power generation by building a ton of coal plants over the border in Mexico) The point was more that the Green New Deal can only address a small fraction of future world emissions, and that fraction is not large enough to prevent catastrophe. That doesn't mean that we shouldn't reduce emissions! Just that unilateral reductions might not be the way to go. (Imagine the US unilaterally giving up nukes in the 1960s and then trying to convince the Soviet Union to do the same - it would be far less likely than agreeing to both disarm at the same time. IMO negotiations on emissions reduction are like this)
