Global Warming: Causes, Consequences, and Solutions

Global warming refers to the gradual increase in the average annual temperature worldwide, primarily caused by the greenhouse effect. Greenhouse gases like carbon dioxide, methane, nitrous oxide, and CFCs contribute to this phenomenon, leading to rising sea levels, human health issues, forest degradation, and climate variations. Explore the impacts on economies, agriculture, and aquatic ecosystems in detail.
