Climate engineering methods that reduce the sunlight or shortwave radiation that hits the Earth (i.e. solar radiation management) include space-based sunshades and reflectors, stratospheric aerosol injection, marine cloud brightening and increases in the albedo or reflectivity of areas of the Earth. These approaches include include space-based sunshades and reflectors, stratospheric aerosol injection, marine cloud brightening, land albedo enhancement and Earth radiation management (Ming et al., 2014). Of these climate engineering approaches, space-based sunshades and reflectors, stratospheric aerosol injection and marine cloud brightening all, individually, have the potential to bring the average temperature of the Earth back to pre-industrial levels (Lenton and Vaughan, 2009). Marine cloud brightening is a climate engineering approach that aims to increase the albedo (reflectivity) of ocean clouds by seeding them with seawater aerosol (Latham et al., 2008). Ocean albedo modification is a solar radiation management climate engineering approach that aims to increase the reflectivity of the surface of the ocean.

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.

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.

Climate-altering technologies and measures (CATM) – also sometimes referred to as climate or geo-engineering – refer to a broad set of methods and technologies that aim to deliberately alter the climate system in order to alleviate the impacts of climate change (IPCC, 2014). At the 2017 UN Climate Change Conference (COP23), experts expressed the need to discuss the governance of CATM, especially in relation to stratospheric aerosol injection (SAI), due to the great uncertainties and potential side effects of these measures (UN News, 2017). These include the UNEP Independent Expert Review on solar radiation modification research and deployment, the report of the Human Rights Council Advisory Committee on the impact of new technologies for climate protection on the enjoyment of human rights (A/HRC/54/47), the UN Convention on Biological Diversity on certain restrictions on solar insolation activities that may affect biodiversity (CBD/DEC/X/33/8w), and mentions of SRM in reports of the Intergovernmental Panel on Climate Change.

# Need To Know: Geoengineering and Cloud Seeding. No comments on Need To Know: Geoengineering and Cloud Seeding. Techniques to deliberately alter Earth’s climate, such as geoengineering and cloud seeding, have been in the news following the devastating floods in Texas. Lamb, an associate research scientist in the Department of Earth and Environmental Engineering at Columbia University, introduces the science underlying geoengineering and weather modification and discusses their implications for future climate mitigation strategies. Another set of methods, referred to under the umbrella of Solar Radiation Management (SRM), aim to increase the reflection of sunlight from the Earth’s atmosphere in order to cool the Earth’s climate. The most studied of these methods is stratospheric aerosol injection, which proposes to put sulfate aerosols high up in the Earth’s atmosphere to cool the climate (this is similar to the cooling effect that is observed after a large volcanic eruption, such as Mount Pinatubo in 1991). atmospheric science, climate change, cloud seeding, geoengineering, Kara D.
