Climate engineering, also known as geoengineering, refers to the deliberate and large-scale modification of the Earth's climate in order to mitigate the effects of climate change. This can involve various techniques, such as reflecting sunlight back into space, removing carbon dioxide from the atmosphere, or modifying clouds to increase their reflective properties. While climate engineering has the potential to address some of the impacts of climate change, it is also a controversial and largely untested field with potentially unknown risks and consequences. Critics argue that it may have unintended and negative impacts on the environment and society, and could potentially shift the focus away from more sustainable solutions, such as reducing greenhouse gas emissions. Research in the field of climate engineering is ongoing, with scientists studying the feasibility and potential risks of various techniques, as well as the ethical, legal, and governance implications of implementing such strategies.
