Why might Earth's temperature continue to increase for a time even if all emission of greenhouse gasses ceased?

Question

Quizplus · Accepted Answer

The Answer is Because of the long lifetime of many greenhouse gases, even if emissions ceased, the gases already emitted will remain in the atmosphere for many years. Since it takes time for Earth to heat, the temperature will continue to rise until it stabilizes at the temperature dictated by the current levels of greenhouse gases.
