Overview - the CO₂ timeline 🍃
- Carbon dioxide (CO2) has had its ups and downs over geological history.
- More CO2? 🔥Hotter temps.
- Less CO2? ❄️Cooler temps.
A blast from the past - the carboniferous period 🦕
- Early Carboniferous (350 million years ago):
- 🌡️ Around 20°C
- CO2 levels: ☁️ High at 1,500 ppm (parts per million)
Real-world example: Imagine a tropical climate, kinda like Florida on steroids!
- Middle Carboniferous (300 million years ago):
- 🌡️ Cooler at around 12°C
- CO2 levels: ☁️ Dropped to 350 ppm
Real-world example: It's like going from tropical Miami to a spring day in New York in just 50 million years! 🏖️➡️🗽
The big CO₂ picture - last 600 million years 🌏
- Generally, Earth had CO2 levels higher than 400 ppm.
- Only two exceptions:
- Carboniferous Period 🌴
- Our current age (The Quaternary Period) ❄️
- Current CO₂ levels? ☁️ Less than 400 ppm. But here's the twist...
