Introduction Geoengineering is a term that describes a range of technological approaches to mitigate or offset the effects of climate change. It includes a variety of methods to manipulate the Earth's climate system, such as changing the reflectivity of clouds, capturing and sequestering carbon dioxide (CO2) from the atmosphere, and designing artificial trees. While some argue that geoengineering is the most viable solution to tackle climate change, others are concerned about its unintended consequences and ethical implications. In this article, we will explore the different approaches to geoengineering and their pros and cons. Part 1: Types of Geoengineering 1. Solar Radiation Management (SRM) SRM is the most widely discussed form of geoengineering. It involves reflecting more sunlight back into space to reduce the Earth's overall heat absorption. The two most prominent techniques are: a) Stratospheric Aerosol Injection (SAI) SAI involves injecting reflective particles, such a...
