Global warming

Global warming refers to the long-term increase in Earth’s average surface temperature due to human activities, primarily due to the release of greenhouse gases into the atmosphere. These gases, such as carbon dioxide and methane, trap heat from the sun as a greenhouse effect, leading to a gradual rise in temperatures worldwide. This phenomenon results in various environmental changes, including melting polar ice caps, rising sea levels, ocean acidification, altered weather patterns, and disruptions to ecosystems and biodiversity.
