🌍 Global Warming Notes

✅ Definition

Global warming refers to the long-term rise in Earth’s average surface temperature due to increased concentrations of greenhouse gases in the atmosphere, primarily caused by human activities such as burning fossil fuels, deforestation, and industrial processes.

🔥 Causes of Global Warming

1. Greenhouse Gases (GHGs): Excess CO₂, CH₄, N₂O, CFCs trap heat.

2. Burning of Fossil Fuels: Coal, oil, natural gas release CO₂.

3. Deforestation: Fewer trees → less carbon absorption.

4. Industrialization: Factories emit pollutants and gases.

5. Agriculture: Livestock releases methane; fertilizers release nitrous oxide.

6. Urbanization: Overpopulation, transportation, and construction add emissions.

🌡️ Effects of Global Warming

1. Climate Change: Rising global temperatures.

2. Melting of Glaciers & Ice Caps: Causing sea-level rise.

3. Extreme Weather Events: Heatwaves, floods, droughts, cyclones.

4. Loss of Biodiversity: Threat to wildlife and ecosystems.
