Climate engineering, according to Harvard’s Solar Geoengineering Program, is a broad category of technologies meant to alter the climate in order to reduce climate change. There are two main types of climate engineering: carbon dioxide removal and solar radiation management [1]. Technologies in this category attempt to change the atmosphere by removing carbon dioxide, which would “address the root cause of climate change — the accumulation of carbon dioxide in the atmosphere” [2]. The other major form of climate engineering is solar radiation management (SRM), which consists of reflecting solar radiation (sunlight) away from the Earth’s surface in order to reduce the amount of energy in the atmosphere. “Ocean-Based Carbon Dioxide Removal (CDR) and Its Implications for the Sustainable Development Goals.” University of Cambridge - Centre for Science and Policy, November 18, 2022. [9] Daisy Dunne, “Explainer: Six ideas to limit global warming with solar geoengineering,” *Carbon Brief: Clean on Climate*, 9 May 2018.

Also known as "geoengineering," climate engineering is the intentional large-scale intervention in the Earth’s climate system to counter climate change. Given the daunting challenge of keeping the rise in global temperatures in check, some researchers are also working to understand the risks and potentials of “geoengineering” or climate engineering technologies. It includes techniques to remove carbon dioxide from the atmosphere, and technologies to rapidly cool the Earth by reflecting solar energy back to space. Solar geoengineering technologies cool the earth by reflecting sunlight back into space—but they pose many risks, challenges, and uncertainties. Some climate scientists want to start atmospheric field experiments with sun-reflective aerosols and other solar geoengineering technologies to further understand their risks and potential benefits. They warn of the risk, or “moral hazard,” that investments in solar geoengineering may diminish efforts at reducing net carbon emissions through proven and affordable means like renewable energy, and that they also may increase geopolitical conflict over “who decides” what the climate goals of deploying SRM would be.

However, research shows that using solar geoengineering could indirectly lower the amount of CO2 in the atmosphere by stemming permafrost melt, reducing energy-sector emissions and causing changes to the carbon-cycle feedback. Aerosol injection could have an edge on other proposed forms of solar geoengineering because it would not require a large technological leap to become a reality, Jones says:. These brighter clouds would reflect away more sunlight, says Prof Douglas MacMartin, an engineering researcher from Cornell University, who contributed to the US House of Representatives’ hearing on geoengineering. Earlier this month, MacMartin, Keith and Prof Katharine Ricke, a climate scientist from the University of California, San Diego, published a research paper exploring how solar geoengineering – via releasing aerosols into the stratosphere – could be used as part of an “overall strategy” for limiting global warming to 1.5C, which is the aspirational target of the Paris Agreement. However, the researchers point out that using solar geoengineering to hold global warming to 1.5C would not have the same environmental effect as reaching the target using mitigation.

WRI [recently analyzed](https://www.wri.org/research/climate-adaptation-investment-case) more than 300 adaptation investments and found that over half of them are also expected to reduce GHG emissions in the long run; for example, by adopting climate-smart farming practices, bringing trees and green spaces to cities, or introducing more resilient renewable energy sources. This, in turn, reduces demand for air conditioning and cuts energy-related emissions — [both of which are rising](https://www.wri.org/insights/climate-change-effects-cities-15-vs-3-degrees-C) as the planet warms. [When harvested sustainably](https://www.wri.org/insights/mass-timber-wood-construction-climate-change), wood may drive fewer emissions than materials like concrete while also minimizing flood damage and reducing losses. These are critical ecosystems: In addition to storing [17% of all forest carbon](https://www.wri.org/insights/4-ways-indigenous-and-community-lands-can-reduce-emissions), they provide [habitat for biodiversity](https://www.wri.org/insights/indigenous-and-local-community-land-rights-protect-biodiversity) and resilience benefits for nearby communities, such as climate regulation and water security.
