Carbonate-silicate cycle predictions of Earth-like planetary climates and testing the habitable zone concept [PDF]
Nature Communications, 2020 In the habitable zone concept, a planet’s carbon dioxide-water greenhouse maintains surface liquid water. Here, the authors estimate how many Earthlike exoplanets are needed to detect a relationship between stellar flux and the atmospheric carbon dioxide

Seasonal Thaws under Mid- to Low-pressure Atmospheres on Early Mars
The Astrophysical Journal, 2023 Despite decades of scientific research on the subject, the climate of the first 1.5 Gyr of Mars' history has not been fully understood yet. Especially challenging is the need to reconcile the presence of liquid water for extended periods of time on the ...

Moist Convection Is Most Vigorous at Intermediate Atmospheric Humidity
The Planetary Science Journal, 2023 In Earth’s current climate, moist convective updraft speeds increase with surface warming. This trend suggests that very vigorous convection might be the norm in extremely hot and humid atmospheres, such as those undergoing a runaway greenhouse ...

Transient climate–carbon simulations of planetary geoengineering [PDF]
Proceedings of the National Academy of Sciences, 2007 Geoengineering (the intentional modification of Earth's climate) has been proposed as a means of reducing CO 2 -induced climate warming while greenhouse gas emissions continue. Most proposals involve managing incoming solar radiation such that future greenhouse gas forcing is counteracted by reduced solar forcing ...

The Astrophysical Journal, 2023 In this study, we employ a cloud-resolving model to investigate how gravity influences convection and clouds in a small-domain (96 × 96 km) radiative–convective equilibrium.

Superhabitability of High-obliquity and High-eccentricity Planets
The Astrophysical Journal, 2023 Planetary obliquity and eccentricity influence climate by shaping the spatial and temporal patterns of stellar energy incident at a planet’s surface, affecting both the annual mean climate and magnitude of seasonal variability.

Arctic climate and atmospheric planetary waves [PDF]
Geophysical Research Letters, 2001 Analysis of a fifty‐year record (1946–1995) of monthly‐averaged sea level pressure data provides a link between the phases of planetary‐scale sea level pressure waves and Arctic Ocean and ice variability. Results of this analysis show: (1) a breakdown of the dominant wave 1 pattern in the late 1960's, (2) shifts in the mean phase of waves 1 and 2 since

The Astrophysical Journal Letters, 2023 Planetary organic hazes can play a significant role in influencing a planet’s radiative balance and climate, with their impact determined by the optical properties of the haze.
