Other methods of geoengineering – that is, consciously manipulating the climate – include painting the roofs of houses white in order to increase the reflection of sunlight, covering deserts with reflective plastic, and fertilizing the seas with iron in order to increase the absorption of CO2.
把屋顶漆成白色以增强阳光反射、用反光塑料覆盖沙漠、以及在海水中注入铁离子以增加对二氧化碳的吸收，这些地球工程方法都可以刻意操控气候。
