Reducing the impacts of human-caused climate change through the use of bioenergy with carbon capture and storage – better known as BECCS – could have major consequences for wildlife, forests and water resources, a new study shows. To understand how BECCS may affect the planetary boundaries, the researchers ran a series of models that considered both future climate change and how agricultural land use patterns may differ in the future. To understand how the rapid termination of solar generation could affect wildlife, the researchers used models to compare changes in temperature and rainfall under a scenario in which SRM runs from 2020 until 2070 to a scenario with no geoengineering and an intermediate level of greenhouse gas emissions (RCP4.5). The change in temperature velocity under (a) a modelled scenario including the introduction of solar geoengineering, (b) the termination of solar geoengineering, (c ) the current climate between 1960 and 2014 and (d) a world without solar geoengineering with moderate emissions (RCP4.5).

Abstract. Climate change damages are expected to increase with global warming, which could be limited directly by solar geoengineering.

China launched a large, government-funded program in 2017, while in the United States universities like Harvard (though its major effort shuttered in 2024), the University of Chicago and the University of Washington have been leaders in the field.12 A 2021 report from the US National Academy of Sciences argued it was time to create a transdisciplinary geoengineering research program in the United States, focused on developing “policy-relevant knowledge,” not advancing deployment.3 Two years later, in June 2023, a Congressionally-mandated report from the White House Office of Science and Technology Policy echoed the Academy’s recommendations and laid out a US research program on solar radiation modification, noting such a program would, “…enable better-informed decisions about the potential risks and benefits of SRM as a component of climate policy.”4. Despite the risks and shortfalls of geoengineering as a climate solution, it is likely to increase in its appeal as a climate shortcut as concern over accelerating climate impacts grows.9 Technologically advanced Global North countries may see it as a climate fix that diminishes the need for changes in social and economic behavior that are perceived to be politically risky.

Geoengineering could be crucial in the fight against climate change. But first scientists need to learn how to talk to the public about it.

We find that supplementing politically pledged mitigation with moderate solar geoengineering can achieve the 1.5°C target, with climate damages
