So all of these are necessary wedges to add to have a chance of delivering 1.5, if you assume, what I think my IPCC colleagues would call an orderly phase out of the fossil fuel economy. But, of course, I would like to turn that around to say, well let's take an Earth system perspective on this, 00:22:02 and just look at the tipping points, the buffering capacities, how the planetary boundaries are doing, and build it up from that perspective. And then you end up with the result that shows that the budget is gone.
