Could we avert climate change by pulling carbon dioxide out of the atmosphere? Could we not just stop, but actually *reverse* the damage done? Unfortunately, most don't fully appreciate just quite how much CO2 we've emitted and the outrageous scale of the problem facing us. Today, we apply the fundamental principles of thermodynamics to question whether this is even feasible.Written & presented by Prof. David Kipping. Edited by Jorge Casas.
