Sure. But if we stopped emitting greenhouse gases, 100%, right now... we would still be absolutely fucked. Temperatures would continue to rise. Ice sheets would continue to melt. We would still see an increase of 5x what we've already experienced over the next few decades.
(See here - and note that article is four years old.)
We're slowly, SLOWLY transitioning to renewable, sustainable energy around the world. If everyone sticks to the Paris Agreement numbers strictly, that will still take decades. We're already decades past the point of "we're fucked."
We should be on the "solve the problem" stage, not the "how do we stop making the problem worse" stage.
