Underestimated future climate change?

A new study by Thomas Frölicher suggests that the Earth's atmosphere could continue to warm for hundreds of years after a complete stop of CO2 emissions, leading to a 25% increase in global temperature. The ESM2M climate model reveals that regional ocean heat uptake is crucial in understanding the effects of climate change.
