One-third of Mars’ surface has shallow-buried water, but it is currently too cold for use by life. Proposals to warm Mars using greenhouse gases require...
The five artificial greenhouse gases identified by University of California, Riverside astrobiologist Edward Schwieterman and his colleagues would be detectable...
Early Mars had rivers, but the cause of the transition from a wet planet to dry remains unknown. Past Martian climate can be probed using the distribution...
Mars is cold today but once had water lakes and flowing rivers. The early warm climate cannot be explained by basic models of the early Mars greenhouse...
Methane present in the early Martian atmosphere, together with carbon dioxide and hydrogen may have created a greenhouse effect on the planet 3.5-4.5 billion...
Using spectroscopic instruments operated by the U.S. DoE’s Atmospheric Radiation Measurement Climate Research Facility, scientists have directly observed...
