The Basics of Climate Change
Understanding how our atmosphere protects (and gets hurt by) our planet
What's Happening?
Our atmosphere naturally protects Earth by trapping heat from the sun - like a blanket! Without this, Earth would be a frozen, lifeless rock. But humans have added SO much CO₂ and other greenhouse gases that the blanket is getting TOO THICK!
💡 Did You Know? Before factories existed, the air had 280 ppm CO₂. Today? Over 420 ppm! That's 50% more in just 150 years!
Where Does CO₂ Come From?
- 🚗 Cars burning gasoline
- 🏭 Factories burning coal
- ⚡ Power plants generating electricity
- ✈️ Airplanes and jets
- 🪚 Cutting down trees (removes CO₂ absorbers!)
- 🐄 Cows producing methane gas
Why Climate Change Matters
The real impacts happening RIGHT NOW
What's Changing?
When Earth gets even 1-2°C warmer, EVERYTHING changes. Ice melts, storms get stronger, animals lose homes, and entire ecosystems suffer. Let's look at the real impacts:
🌍 Real Examples Happening NOW
- 🐻 Polar Bears: Losing sea ice homes where they hunt seals. Many are starving.
- 🪸 Coral Reefs: Bleaching and dying from warm ocean water. Turning white and dead.
- 🏝️ Island Nations: Sinking as oceans rise. Some will disappear completely!
- 🌪️ Hurricanes & Storms: Getting more powerful and dangerous each year.
- 🔥 Wildfires: Spreading faster and burning hotter. Destroying homes and forests.
- 🌾 Droughts: Destroying crops, causing food shortages and famines.
- 🦗 Insects Disappearing: Some species down 75% in just 50 years!
⚠️ The Bad News: If we don't act soon, things could get MUCH worse. Some changes might be permanent.
✨ The Good News: We STILL have time to fix this! Every choice we make TODAY changes the future.

The Greenhouse Effect Explained
The science behind why our planet is warming
How Does It Work? (Step by Step)
- ☀️ Sun's Energy Arrives: The sun sends rays to Earth. Some bounce back to space, but most pass through.
- 🌍 Earth Gets Heated: Earth's surface absorbs the sun's energy and gets warm.
- 🔥 Heat Bounces Back: Warm Earth radiates that heat back up toward space.
- 💨 Gases Trap Heat: Greenhouse gases catch some of that heat and hold it!
- ↩️ Heat Bounces Down: The trapped heat bounces back down to Earth.
- 🌡️ Planet Gets Warmer: More heat gets trapped, so Earth gets hotter and hotter!
🌡️ Key Greenhouse Gases
- CO₂ (Carbon Dioxide): From cars, factories, and burning fossil fuels. The biggest culprit!
- 🐄 CH₄ (Methane): From cows and decomposing waste. 28x more powerful than CO₂!
- 💧 H₂O (Water Vapor): Natural, but increases when it's warmer (creates a feedback loop!)
- N₂O (Nitrous Oxide): From fertilizers and factories.
🎓 Important: The greenhouse effect is NATURAL and NECESSARY! Without it, Earth would be -18°C. The problem is we've added TOO MUCH extra greenhouse gas!

Scientific Evidence
What the data shows us
📊 The Facts (97% of Scientists Agree!)
- 🌡️ Temperature Rise: Earth warmed 1.1°C in the last 100 years. That's FAST!
- 📈 CO₂ Levels: Rising every single year - now 420 ppm (highest in 3 million years!)
- 🧊 Arctic Ice: Shrinking 13% per decade. Summer ice is disappearing!
- 🌊 Ocean Levels: Rising 3.3mm per year. Small islands will be underwater soon.
- 🔴 Heat Records: Heat records broken almost EVERY year now.
- 🌪️ Extreme Weather: Hurricanes, droughts, and floods becoming more common.
- 🐝 Species Loss: Extinction rate 100-1000x faster than natural rate!
🔬 Why Do Scientists Know This?
- 📏 Thermometers: Measuring temperature worldwide for 150+ years
- 🧬 Ice Cores: Ancient ice shows CO₂ levels from 800,000 years ago!
- 📡 Satellites: Tracking Earth's temperature and ice from space
- 🌊 Ocean Sensors: Measuring water temperature and acidity
- 🌳 Tree Rings: Showing past climate patterns
✅ Consensus: 97% of climate scientists agree humans are causing climate change. That's more agreement than on any other scientific topic!
