Amplified Cooling Of Snowball Earth From A Salt-albedo Feedback
[Climate of the Past] It is believed that the atmospheric circulation on Snowball Earth produced a net ablation zone exposing bare sea ice.
![This global map of Mars (greys) is overlaid with a map of ice “consistency,” C. Values of C near one (dark blue) indicate a high likelihood of ice in three independent mappings. Lower values of C (lighter blues) indicate lower confidence in ice being present, and indicate detection in at least one dataset. The extreme north and south are both rich in ice (dark blues), ice is absent near the equator, and the presence of ice is uncertain (light blues) in the mid-latitude regions best for astronauts.

Laying Odds On The Potential For Martian Water
[PSI] We know Mars has water ice in its polar regions, but astronauts (and their solar powered equipment!) would much rather experience life closer to Mars’ equator. As NASA looks […]

Exploring The Orbital Stability Of Large, Lightweight Mirrors Around Exoplanets
Extraterrestrial civilizations might place large, lightweight mirrors into orbit around an exoplanet, either to alter its climate or to provide illumination to the planet’s dark side. We previously analyzed the […]
