- What is Permafrost
- Organic Carbon Material
- Carbon Dioxide
- Re emitted Infrared radiation
- Permafrost
- Methane gas
- Infrared radiation
- Greenhouse Gasses Increase
- Microbes Decompose Organic Material
- Permafrost is frozen organic carbon materials from a long time ago
- Increase in Temperature Melts More Permafrost
- Due to an increase in greenhouse gasses, there is an increase in back radiation, and as such, an increase in earths energy input. This results in a warming planet and so the permafrost has begun to melt, uncovering the things frozen inside.
- Increase in Temperature Melts More Permafrost
- As the organic carbon materials inside are uncovered, they begin to break down and release carbon dioxide and methane gas into the atmosphere with are greenhouse gasses. This results in a greater amount of infrared back radiation. This back radiation increases earth's temperature.
- Increase in Temperature Melts More Permafrost
- As the back radiation increases, so does the earth's temperature. The permafrost melts and more organic carbon is exposed, causing an influx of carbon dioxide and methane gas into the atmosphere.
- With Back radiation continuing to increase, as does the earth's temperature. Permafrost continues to melt and the carbon material decomposes, continuing the release of the greenhouse gasses and with is back radiation.
- With Back radiation continuing to increase, as does the earth's temperature. Permafrost continues to melt and the carbon material decomposes, continuing the release of the greenhouse gasses and back radiation. This loop increases the earth's temperature.
