Global Climate Change
Scott Fortmann-Roe
A model of Global Climate Change driven by the impact of Carbon Dioxide on the Greenhouse Effect. This model contains a physical model of energy inflowsΒ β˜€οΈΒ and outflows from the Earth (primary source). And a simple model of carbon dioxide sources and sinks in the atmosphere (primary source).

The energy model assumes inflowing short-wave solar radiation that does not interact with the atmosphere. A fraction of this is reflected immediately (e.g. by snow and ice cover). The remaining is absorbed 🌎 and re-radiated as long-wave infrared which can be captured by the atmosphere ☁️. The fraction captured by the atmosphere is related to the level of Carbon Dioxide in the atmosphere.

This model tracks Carbon Dioxide emissions from burning fossil fuels 🏭 and land use changes 🚜 (e.g. deforestation). It also tracks removal of Carbon Dioxide from the atmosphere into a land sink 🌲 (e.g. vegetation) and the an ocean sink πŸ–.

πŸ§ͺ Experiment with different levels of emissions to see their impact on global average temperatures. You can also compare predicted temperatures and Carbon Dioxide levels to historical data.
