I never said that. Sure, there may be more ice ages at some far distant future , but there is a non-zero chance humans will be extinct by then. The cooling effects of the present Milankovitch cycle is being overridden by anthropogenic climate change and on its current trajectory the warming will tip us into new, ever-worsening equilibrium states that we will not be able to reverse. If some of these earth system tipping points are crossed they will become self-perpetuating, and it won't really matter what we do then. The effects will last for potentially thousands of years. So yes, for all intensive purposes, we have effectively reversed this coming ice age
