Came across it on radio last evening. I got curious.
Geoengineering, the large-scale manipulation of a specific process central to controlling Earth’s climate for the purpose of obtaining a specific benefit. Global climate is controlled by the amount of solar radiation received by Earth and also by the fate of this energy within the Earth system—that is, how much is absorbed by Earth’s surface and how much is reflected or reradiated back into space. The reflectance of solar radiation is controlled by several mechanisms, including Earth’s surface albedo and cloud coverage and the presence in the atmosphere of greenhouse gases such as carbon dioxide(CO2). If geoengineering proposals are to influence global climate in any meaningful way, they must intentionally alter the relative influence of one of these controlling mechanisms.
Most geoengineering projects exist to reverse negative effects of industrial civilization on Earth's climate. For instance, Earth's atmosphere and stratosphere are taking on increased levels of greenhouse gas emissions such as carbon dioxide (CO2) and methane (CH4) due to deforestation and burning fossil fuels. To address atmospheric carbonization, humans can engage in resource conservation and carbon emissions reduction, yet geoengineering schemes go a step further by seeking to actively remove greenhouse gasses from the atmosphere and stratosphere.
