Climate engineering refers to a set of technologies and practices aimed at deliberately manipulating or altering Earth's climate in order to mitigate the effects of global warming, climate change, and other environmental issues. This can involve various methods such as injecting reflective particles into the atmosphere to reduce sunlight absorption, creating artificial trees that absorb carbon dioxide from the air, or even manipulating weather patterns through cloud seeding. The goal is to find ways to counteract human-induced climate change and its impacts on ecosystems, agriculture, and human health. However, there are concerns about the potential risks, unintended consequences, and ethical implications of using such technologies.
