These feedback loops are in total larger than our emissions, so once we hit them in the coming decades, the global warming would continue increasing for at least a few centuries even if all humans would be dead and make zero emissions. Hitting zero emissions now (which IMHO is unrealistic) would stop global warming at something like +2C level. Hitting zero emissions in 2050 will still mean a runaway global warming, and fixing that would require some effects that go way beyond zero emissions e.g. large scale carbon sequestration (effectively negative emissions), geoengineering sci-fi or something like that. In 1980 it would have been sufficient to "just" reduce the growth.
