The Moist Greenhouse is Sensitive to Stratospheric Temperature
Ramses M. Ramirez
In this Research Note, I use my single-column climate model to explicitly show that the moist greenhouse surface temperature threshold is sensitive to stratospheric temperature. I…
A warmer and wetter solution for early Mars and the challenges with transient warming
Ramses M. Ramirez
The climate of early Mars has been hotly debated for decades. Although most investigators believe that the geology indicates the presence of surface water, disagreement has persist…
A Volcanic Hydrogen Habitable Zone
Ramses Ramirez, Lisa Kaltenegger
The classical habitable zone is the circular region around a star in which liquid water could exist on the surface of a rocky planet. The outer edge of the traditional N2-CO2-H2O h…
Habitable Zones of Post-Main Sequence Stars
Ramses Ramirez, Lisa Kaltenegger
Once a star leaves the main sequence and becomes a red giant, its Habitable Zone (HZ) moves outward, promoting detectable habitable conditions at larger orbital distances. We use a…
Testing the Early Mars H2-CO2 Greenhouse Hypothesis with a 1-D Photochemical Model
Natasha Batalha, Shawn D. Domagal-Goldman, Ramses Ramirez +1
A recent study by Ramirez et al. (2014) demonstrated that an atmosphere with 1.3-4 bar of CO2 and H2O, in addition to 5-20% H2, could have raised the mean annual and global surface…
