If carbon emissions dropped to zero today, there is enough carbon in the atmosphere to permanently raise the temperature and potentially enough to kick off nasty positive feedback loops like permafrost methane. Assuming we could hit zero today is of course wildly optimistic. Even reaching an equilibrial state of carbon inflow and carbon outflow would mean approximately halving emissions, rather than tinkering around the edges.
