[PPS08-P15] What happens if you run out of ocean?
Keywords:habitability, exoplanet, earth, outreach, climate
Here we explore how changes to the fraction of the planet surface covered by water can affect the atmospheric carbon dioxide levels (a greenhouse gas) due to changes in a simple carbon cycle. We show that even altering this one property of an otherwise Earth-like planet can make major changes to the heat retention capabilities of the atmosphere.
We present our results as an interactive webpage where users can try different fractions of land and sea and see how the levels of carbon dioxide change. Our main goal is for users to explore for themselves how even small changes can greatly influence planetary environment and therefore, care must be taken in claiming a new world is truly “like Earth”.
