The Climate Crisis Unveiled The greenhouse effect is a crucial process that makes Earth habitable. Overview of the Natural Greenhouse Effect The greenhouse effect is a crucial process that makes Earth habitable. Without it, the planet's average surface temperature would be a frigid - 18 °C, which is far too cold to support most life forms (National Aeronautics Space Administration [NASA], 2023). This natural phenomenon occurs when greenhouse gases (GHGs) such as carbon dioxide (CO₂), methane (CH₄), nitrous oxide (N₂O), and water vapor trap heat in the Earth's atmosphere. These gases function like a blanket, allowing sunlight to enter the atmosphere and warm the surface while preventing some heat from escaping into space. This delicate balance enables the development of the ecosystem and human civilization by maintaining stable temperatures on Earth for thousands of years. However, this balance is now being disrupted due to anthropogenic activities. Since the Industrial Rev...
