Solar Radiation Management (SRM) is a technology used for what purpose?

Solar Radiation Management (SRM) is a set of techniques aimed specifically at reflecting a portion of the sun's energy back into space to mitigate the effects of climate change. This approach is part of geoengineering strategies that target the Earth's atmosphere to reduce global warming by controlling the amount of solar radiation that reaches the surface. By reflecting sunlight away, SRM helps lower surface temperatures and potentially counteract some of the adverse effects of climate change, such as rising sea levels and extreme weather events.

In contrast, the other options do not align with the primary purpose of SRM. Storing solar energy relates to energy capture and use, not reflection. Reducing pollution pertains to emissions controls and environmental regulations rather than solar reflection techniques. Increasing agricultural productivity involves improving crop yields and farming practices, which is unrelated to the processes involved in SRM. Hence, the focus of SRM on reflecting the sun's energy is what distinguishes it as the correct answer in this context.
