Global warming refers to the long-term increase in Earth's average surface temperature due to the accumulation of greenhouse gases, such as carbon dioxide and methane, primarily from human activities like burning fossil fuels and deforestation. This rise in temperature leads to significant environmental changes, including more frequent and severe weather events, rising sea levels, and shifts in ecosystems and wildlife habitats. These impacts threaten biodiversity, food security, and human health, making it a critical global challenge.
