Saving the Planet!

 Today's class consisted of learning about Earth billion and billions of years ago, 4.6 billion to be exact. We learned about each stages of Earth, it goes like this. 

• Hadean Earth - 4.6 billion years ago
• Late Archean to Early Proterozoic - 2.8 billion years ago
• Rodinia - 900 million years ago
• Snowball Earth - 650 million years ago
• Cambrian - 500 million years ago
• Jurassic - 170 million years ago
• Pleistocene
• Earth today!

Then we learned about greenhouse gases and the effect of CO2. The rise in demand for factory production leads to CO2 rise in our atmosphere. 

We used a very simple climate change model. I will attach my model below. I chose to be very aggressive and decrease the carbon by 1 gigaton every 10 years. My model was able to stay under the temperature limit which is GREAT!
