Climate Change – Introduction & Basic Concepts
Climate change refers to long-term changes in temperature, precipitation, and other atmospheric conditions on Earth. It is mainly caused by the increase in greenhouse gases.
What is Climate Change?
Climate change is the long-term alteration in Earth’s climate patterns, including temperature rise, rainfall changes, and extreme weather events.
Greenhouse Effect
- Gases like CO₂ and CH₄ trap heat in the atmosphere
- Leads to global warming
- Essential but excessive levels are harmful
Major Causes
- Burning of fossil fuels
- Deforestation
- Industrial pollution
Effects
- Rising global temperatures
- Melting glaciers
- Sea-level rise
- Extreme weather conditions
Key Points for Exams
- Greenhouse gases → CO₂, CH₄
- Global warming → temperature rise
- Climate change → long-term impact
Summary
Climate change is a global challenge that affects the environment, economy, and human life.
