Yet, billions will die. Regardless. Setting aside snide remarks, the concern most people have for the environment is not about "life", it is about our civilization. We have seen huge advances in quality of life in the past 100 years, because of increases in medicine, trade, and mobility. These characteristics rely on a relatively peaceful coexistence across the globe. The fear is that increased survival pressure will void most of those advances. If global trade breaks down, we might lose the technology and infrastructure that enables us to feed 7+ billion people. So regardless of whether the Earth's climate will kick us out, we still might end up returning to population levels of the 1900s.
