Note though that the warming was always going to continue even after reducing emissions to zero, because it takes time for a complex system to settle into a new stable state. This is only one of the many effects that make highly nonlinear systems difficult to intuitively understand. The math is clear, though (although many of the myriad feedback loops involved are still poorly understood).
