> Anthropogenic emissions dominate climate change, and will for the remainder of the athropocene. That's true by definition, since the anthropocene is defined as the geologic era where humans have had a measurable effect on the geologic record. The anthropocene may or may not actually exist for future species' geologists. One fairly likely scenario I can imagine is that global warming leads to mass migrations, which lead to nuclear war, which lead to the deaths of 90% of the human population and the reversal of anthropogenic climate change. Boom, global warming solved...except that'll be cold comfort (literally) for the 90% of us who are dead. If it happens, it'll probably happen before 2100, which means the anthropocene will last less than 150 years, a blink of an eye in geologic time. Future dino-geologists will observe it as a very thin layer that led to a change in the radiation signature and composition of elements in the earth's crust, as well as a small mass extinction. Come to think of it, that's not all that different from the K-T boundary.
