The deliberate large-scale manipulation of an environmental process that affects the earth's climate, in an attempt to counteract the effects of climate change.

Origin:

Geo- + engineering.

Examples:

1. Geoengineering techniques include injecting reflective particles into the upper atmosphere to reflect sunlight back into space.
2. Geoengineering is a controversial field that is still in its infancy and is not yet fully understood.
3. The goal of geoengineering is to reduce the amount of solar radiation reaching the earth and thus reduce global warming.
4. Some scientists argue that geoengineering should be used as a last resort to combat climate change.
5. Geoengineering could have unintended consequences and should be carefully researched and regulated.
