The composition of the atmosphere, especially the abundance of greenhouse gases, influences Earth’s climate. Researchers at Purdue University, led by Stephanie Olson, assistant professor of earth, atmospheric, and planetary sciences, have recently found that the presence of salt in seawater can also have a major impact on the habitability of Earth and other planets. The team used a climate model to investigate the climates of worlds with different amounts of salt dissolved in seawater to predict that saltier oceans tend to result in warmer climates, and therefore, can aid in a planet’s ability to host life.
