We are focused on greenhouse gas emissions. World leaders are promising huge reductions. What else do you expect them to do? Do you expect them to tell the truth? They cannot. Emissions will not stop, they will continue at pretty much the same pace. The only thing that will stop them is massive system failure of capitalism. But even if there is collapse, mass unemployment, and emissions go to zero, there is already too much greenhouse gas in the atmosphere.
We need to focus on heat. The energy on earth can be stored as plant material or it can be turned into heat by humans. Heat can only be radiated into space at a fixed rate, so we have to degrow or burn.
