LSE: What is geoengineering and how could it help tackle climate change?

“Geoengineering, also known as climate engineering, describes a range of ways to intervene on a large scale in the Earth’s natural systems – the oceans, soils and atmosphere – to directly combat climate change. They mostly fall into two categories: those designed to remove carbon dioxide (CO2) from the air and those that try to limit the amount of sunlight that reaches the Earth’s surface.”
