🌦️ 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
