But what happens when we achieve the goal of zero carbon dioxide emissions from human actions? Does the climate keep warming, stay the same, or even cool? It turns out this is a critical question for understanding what carbon budgets we have in terms of emissions, if we seek to meet temperature thresholds like 2 degrees Celsius.
