As global temperatures climb, scientists are exploring bold ideas to cool the planet beyond simply cutting emissions. This NOVA film examines geoengineering schemes, from pulling carbon straight out of the air to reflecting sunlight back into space. It weighs the potential of these technologies against their risks and uncertainties. Thought-provoking and grounded, it asks how far we should go to engineer a cooler climate.
