Global warming is the gradual increase in the Earth’s average temperature due to the excessive release of greenhouse gases such as carbon dioxide (CO₂), methane, and nitrous oxide into the atmosphere. These gases trap heat from the sun and make the planet warmer. This process is mainly caused by human activities like burning fossil fuels, cutting down forests, industrial production, and pollution from vehicles.
Global warming has become one of the most serious environmental problems in the world today. The temperature of the Earth has been rising steadily over the past century, leading to climate change and unusual weather patterns.
Causes of Global Warming
- Burning of Fossil Fuels: Coal, oil, and natural gas are burned for electricity, transportation, and industries, releasing huge amounts of carbon dioxide.
- Deforestation: Trees absorb carbon dioxide. Cutting down forests increases greenhouse gases in the atmosphere.
- Industrial Pollution: Factories release harmful gases and smoke that contribute to warming.
- Vehicle Emissions: Cars, buses, and airplanes produce carbon emissions that increase air pollution.
- Agricultural Activities: Some farming methods release methane gas, which is a powerful greenhouse gas.
