Global warming

Global warming refers to the long-term increase in Earth’s average surface temperature due to human activities, especially the emission of greenhouse gases like carbon dioxide (CO₂), methane (CH₄), and nitrous oxide (N₂O).

Key Points:
• 🌍 Cause: Primarily caused by the burning of fossil fuels (coal, oil, natural gas), deforestation, and industrial processes.
• ☁️ Greenhouse Effect: These gases trap heat in the atmosphere, preventing it from escaping into space—this is a natural effect, but human activity has intensified it.
• 📈 Consequences:
• Rising global temperatures
• Melting polar ice and glaciers
• Rising sea levels
• More extreme weather (heatwaves, droughts, storms)
• Ocean acidification
• Disruption of ecosystems and wildlife habitats

Difference Between Global Warming and Climate Change:
• Global warming is specifically about Earth’s rising temperatures.
• Climate change includes global warming plus other effects like changing rainfall patterns, stronger storms, and shifting weather conditions.
