Global warming refers to the long-term increase in Earth’s average surface temperature due to human activities, primarily the emission of greenhouse gases like carbon dioxide (CO₂), methane (CH₄), and nitrous oxide (N₂O). These gases trap heat in the atmosphere, leading to climate changes such as rising sea levels, extreme weather events, and shifts in ecosystems. The primary sources of these emissions include burning fossil fuels (coal, oil, and natural gas), deforestation, and industrial processes. Scientists warn that if global warming continues unchecked, it could lead to severe environmental, social, and economic consequences worldwide.
