    World Climate Research Programme lighthouse activity: an assessment of major research gaps in solar radiation modification research by Jim M. Haywood, Olivier Boucher, Chris Lennard, Trude Storelvmo, Simone Tilmes, Daniele Visioni

    Published 2025-02-01
    “…While future scenarios of climate change frequently include extensive use of terrestrial and marine carbon dioxide removal in the second part of the 21st century, it is unproven that these techniques can be scaled-up to reach the scale required to significantly reduce concentrations of atmospheric carbon dioxide and significant uncertainties and detrimental side-effects exist. These issues have led to increasing interest in so-called “Solar Radiation Modification” whereby the global mean temperature of the Earth is reduced by either blocking a small fraction of sunlight from reaching it or by increasing the Earth’s albedo to reflect a small proportion of incident sunlight back out to space. …”
