Study: Warming already baked in will blow past climate goals

The amount of baked-in global warming, from carbon pollution already in the air, is enough to blow past international agreed upon goals to limit climate change, a new study finds.

But it's not game over because, while that amount of warming may be inevitable, it can be delayed for centuries if the world quickly stops emitting extra greenhouse gases from the burning of coal, oil and , the study's authors say.

For decades, scientists have talked about so-called "committed warming" or the increase in future temperature based on past carbon dioxide emissions that stay in the atmosphere for well over a century. It's like the distance a speeding car travels after the brakes are applied.
