Engineering the Climate: Can Injecting Chemicals in the Sky Help Save the Planet? (Professor David Keith)

Environment
Global
Started July 23, 2026

What if the answer to climate change is not only to cut carbon emissions, but to make the Earth more resilient using tech? Professor David Keith is one of the world’s leading researchers of geoengineering which aims to do just that. Efforts to capture carbon are already underway, but Professor Keith is particularly interested in sunlight reflection - the controversial idea of cooling the planet by reflecting the sun’s rays back into space. To do this, he wants to release sulphur high into the...
