As we recklessly warm the planet by pumping greenhouse gases into the atmosphere, some industrial emissions also produce particles that reflect sunshine back into space, putting a check on global warming that we're only starting to understand. Climate activist Kelly Wanser asks: Can we engineer ways to harness this effect and further reduce warming? Learn more about the promises and risks of "cloud brightening" -- and how it could help restore our climate to health.

Global investment in sunlight reflection methods is nearly zero, despite their potential as emergency climate interventions.

Marine cloud brightening could reflect more sunlight, potentially offsetting up to 2°C of warming with strategic interventions.

Exploration of stratospheric particle dispersal suggests a controlled method could keep global temperatures stable through 2100.
