🌦️ What is Climate Change?

➡️ Long-term changes in temperature and weather patterns

➡️ Can happen naturally (e.g., solar cycle)

➡️ 🌡️ But current rapid change = mostly due to human actions

🔥 What is Global Warming?

➡️ Steady rise in Earth’s surface temperature

➡️ Caused mainly by greenhouse gases (CO₂, CH₄, CFCs, etc.)

➡️ Disturbs Earth’s climate → leads to extreme weather

🛑 Major Causes of Climate Change & Global Warming

🌍 Man-made Causes:

➡️ Deforestation

  ⤷ Fewer trees = more CO₂ in the air

  ⤷ Cuts oxygen supply & disturbs balance

➡️ Burning of Fossil Fuels (vehicles, factories)

  ⤷ Releases CO₂ and other toxic gases

➡️ Industrial Emissions

  ⤷ Factories emit greenhouse gases

➡️ Overuse of ACs & Refrigerators

  ⤷ Releases CFCs → damages ozone layer

➡️ Agriculture

  ⤷ Emits methane & CO₂ (from livestock, fertilizers)

➡️ Overpopulation

  ⤷ More people = more CO₂ from respiration & resource use

🌋 Natural Causes:

➡️ Volcanic Eruptions

  ⤷ Release gases and ash → traps heat

➡️ Water Vapour

  ⤷ More heat → more evaporation → more water vapour → more heat

➡️ Melting Permafrost

  ⤷ Releases trapped greenhouse gases

➡️ Forest Fires

  ⤷ Emit carbon-rich smoke → adds to warming

⚠️ Effects of Global Warming

➡️ 🌡️ Rise in Earth’s Temperature

  ⤷ Melts glaciers → sea level rise → floods

➡️ 🐠 Ecosystem Threats

  ⤷ Coral reefs dying → biodiversity loss

➡️ 🌪️ Climate Disruption

  ⤷ Droughts, floods, cyclones becoming common

➡️ 🦟 Health Risks

  ⤷ Heatwaves, new diseases, malaria spread

➡️ 🏝️ Displacement

  ⤷ Sea-level rise forces people to migrate

📊 Key Facts:

🔹 Earth’s average temperature has increased by 1.2°C since the 1800s

🔹 The last decade (2011–2020) was the warmest ever

🔹 6 biggest emitters: China, USA, India, EU, Russia, Brazil

🔹 45 poorest countries contribute only 3% of emissions

💡 Solutions and Global Actions

➡️ Switch to Renewable Energy (solar, wind)

➡️ Afforestation – Plant more trees

➡️ Sustainable Farming

➡️ Use public transport

➡️ Reduce plastic & energy waste

➡️ Follow global frameworks:

  ⤷ UNFCCC, Paris Agreement, SDGs

🙋‍♀️ Why It Matters:

🌎 Everyone is affected

⚖️ But rich countries must act more

👩‍👧 Future generations need a livable planet

⏳ Every fraction of warming avoided = lives saved

📌 Summary:

🟢 Global Warming = Earth getting hotter

🟢 Caused by CO₂, methane, CFCs (human + natural)

🟢 Impacts climate, health, economy, and future

🟢 Action needed NOW – every degree matters
