I wrote this book to help bridge the gap between Earth System science and ecosocialism — to show socialists why they must understand the Anthropocene, and to show Earth System scientists why they must understand ecological Marxism. I am honored that Unrast Verlag is making it available in German, and I hope it will expand dialogue at the intersections of science and socialism. When Facing the Anthropocene was published in 2016, it reflected, to the best of my ability, the state of scientific knowledge and debate at the time. But the world does not stand still, so it may be helpful to outline some important recent developments in Anthropocene science in the two main fields involved: geology, which has mainly been concerned with formally defining the new epoch; and Earth System science, which studies the global biological, chemical and physical changes that are reshaping the conditions of life on this planet.
