Global warming refers to the long-term increase in Earth's average surface temperature due to human activities, primarily the burning of fossil fuels like coal, oil, and natural gas. This process releases greenhouse gases such as carbon dioxide and methane, which trap heat in the atmosphere, leading to climate change and severe weather patterns. The consequences of global warming are profound, affecting ecosystems, sea levels, and weather systems worldwide. As temperatures rise, we witness more frequent heatwaves, droughts, and floods, threatening biodiversity and human livelihoods. Addressing global warming requires collective action to reduce emissions and transition to sustainable energy sources.
