What geoengineering strategy aims to decrease global warming?

Solar radiation management is a geoengineering strategy designed specifically to reflect a portion of the incoming solar radiation back into space, thereby reducing the amount of heat that reaches the Earth's surface. This approach aims to counteract the greenhouse effect and lower global temperatures, making it a direct method to address global warming. By manipulating how sunlight interacts with the Earth, this strategy has the potential to temporarily cool the planet and mitigate some of the impacts of climate change.

In contrast, carbon sequestration involves capturing and storing carbon dioxide, which is a significant greenhouse gas, but it primarily functions to remove CO2 from the atmosphere rather than directly regulating solar radiation. Landfill management pertains to waste disposal practices and solutions for reducing emissions related to waste, while forestation projects involve increasing tree cover to absorb carbon dioxide, but these are not classified under geoengineering. Neither of these strategies directly addresses the thermal regulation of the Earth’s climate in the manner that solar radiation management does.
