zaneselvans commented on the word geoengineering
Geoengineering is purposefully altering the Earth's large-scale natural systems (as opposed to accidentally, as we've done with greenhouse gasses). Today it's usually considered with respect to climate change. It's kind of like "terraforming", but on Earth! An example sentence: Injecting sulfate aerosols into the stratosphere is currently one of the leading geoengineering proposals.
