On a planetary or large-habitat scale, this refers to the deliberate, mega-engineering efforts to manipulate and stabilize atmospheric and environmental conditions to achieve a desired state—a.k.a. terraforming or climate engineering. It's not just adjusting a thermostat; it's using world-altering methods (like orbiting solar mirrors, releasing engineered gases, or seeding oceans) to warm a frozen Mars, cool a runaway greenhouse Venus, or maintain equilibrium in a massive space habitat. It's the ultimate expression of humanity as a geological force.
*Example: Proposals to melt the Martian ice caps with orbital mirrors to release CO2 and thicken the atmosphere, or spraying sulfate aerosols into Earth's stratosphere to reflect sunlight and combat global warming, are acts of Climate Control. It's planetary-scale gardening with potentially universe-altering consequences.*
