How ancient Mars may have kept its lakes liquid

Successful Liquid Lake Conditions in a Cold Martian Paleoclimate

Editors’ Highlights are summaries of recent papers by AGU’s journal editors. Source: AGU Advances Understanding the paleoclimate of Mars is essential for gaining insights into Mars’ early history and atmospheric conditions. Such information is the key to learning why Mars shifted from a potentially warm, wet planet to the cold, dry desert we see now; whether climate change was gradual or catastrophic, thus informing how terrestrial planets evolv…

How ancient Mars may have kept its lakes liquid

For years, scientists have puzzled over a contradiction on Mars. The planet’s surface is covered with features that look unmistakably like ancient lake beds—shorelines, layered sediments, and minerals that usually form in water. Yet most climate models suggest that early Mars was far too cold for liquid water to last on the surface. A new […] The post How ancient Mars may have kept its lakes liquid appeared first on Knowridge Science Report.
