Which proposed technologies reflect sunlight to reduce warming, funded by investors expecting future demand?

• A. Climate-related investment
• B. Clear-air turbulence
• C. Extreme weather events
• D. Solar geoengineering

Answer: (D)

The idea being tested is technologies that aim to reflect sunlight to cool the planet. The best fit is solar geoengineering, which encompasses proposals to increase Earth's reflectivity or reduce the amount of solar energy that reaches the surface, with the goal of counteracting warming. Investors funding future demand would back research and development in this area because it could become a deployable solution if policy, governance, and market conditions align. The other options don’t describe sunlight-reflecting technologies. Climate-related investment is a broad category of money put into climate solutions in general, not a specific cooling method. Clear-air turbulence relates to aviation and atmospheric motion, not a technology to reduce warming. Extreme weather events are outcomes of climate processes, not a tech approach to reflect sunlight.
