Yeah, exactly. If the change happens as fast as it is happening, you get a mass extinction. If the change happens over thousands of years, biomes have time to migrate.
Using the xkcd timeline as a guide, the temperature change in the last 120 years is about the size of the temperature change between 11,000 and 9,000 BC, which was only mildly disruptive to global ecology.
