Many features of the Martian landscape are thought to have been formed by liquid water flow and water-related mineralogies on the surface of Mars are widespread and abundant. Several lines of evidence, however, suggest that Mars has been cold with mean global temperatures well below the freezing point of pure water. Martian climate modellers considering a combination of greenhouse gases at a range of partial pressures find it challenging to simulate global mean Martian surface temperatures… 
A cold and wet Mars
Water in the Martian interior—The geodynamical perspective
Petrological analysis of the Martian meteorites suggests that rheologically significant amounts of water are present in the Martian mantle. A bulk mantle water content of at least a few tens of ppm
The environment of early Mars and the missing carbonates
Abstract– A model is presented in which the aqueous conditions needed to generate phyllosilicate minerals in the absence of carbonates found in the ancient Noachian crust are maintained by an early
The Climate of Early Mars
The nature of the early martian climate is one of the major unanswered questions of planetary science. Key challenges remain, but a new wave of orbital and in situ observations and improvements in
Hygroscopic salts and the potential for life on Mars.
TLDR
Climate model results show that the RH in the region with chloride-bearing deposits on Mars often reaches the deliquescence points of all three salts, and the temperature reaches levels above their eutectic points seasonally, in the course of a martian year.
Depth of the Martian cryosphere: Revised estimates and implications for the existence and detection of subpermafrost groundwater
[1] The Martian cryosphere is defined as that region of the crust where the temperature remains continuously below the freezing point of water. Previous estimates of its present thickness have ranged
Experimental hydrothermal alteration of basaltic glass with relevance to Mars
Phyllosilicates, carbonates, zeolites, and sulfates on Mars give clues about the planet's past environmental conditions, but little is known about the specific conditions in which these minerals
Aqueous environmental history of Mars revealed by mineralogy and geochemistry of outcrop exposures of sedimentary rocks
Recent high-resolution spectral images and in-situ observations have revealed more than 1000 outcrops of diverse aqueous mineral deposits on Mars. Layered deposits of phyllosilicates (and carbonates)
Tracking the weathering of basalts on Mars using lithium isotope fractionation models
TLDR
Li isotopic data obtained by future exploration of Mars could be relevant to highlighting different processes of Li isotopic fractionation in the past, and therefore to understanding basalt weathering and environmental conditions early in the planet's history.

Early geochemical environment of Mars as determined from thermodynamics of phyllosilicates
TLDR
The results show that Fe3+-rich phyllosilicates probably precipitated under weakly acidic to alkaline pH, an environment different from that of the following period, which was dominated by strongly acid weathering that led to the sulphate deposits identified on Mars.
Geological and geochemical legacy of a cold early Mars
[1] We consider the hypothesis that Mars never experienced an early warm, wet period and the implications of a continuously cold Martian climate for the hydrology and geochemistry of the planet.
Hydrothermal hydration of Martian crust: illustration via geochemical model calculations.
TLDR
The alteration of Shergotty shows the greatest potential for storing water as hydrous minerals, and the alteration of Icelandic rhyolite has the lowest potential, in accord with studies of low-grade alteration of terrestrial rocks.
Sulfur-induced greenhouse warming on early Mars
[1] Mineralogical, geological, geophysical, and isotopic data recently returned from Mars suggest that the delivery of sulfur gases to the atmosphere may have played a significant role in the
Early Mars: How Warm and How Wet?
Early in its history, Mars underwent fluvial erosion that has been interpreted as evidence for a warmer, wetter climate. However, no atmosphere composed of only CO2 and H2O appears capable of
Environmental Effects of Large Impacts on Mars
TLDR
The martian valley networks formed near the end of the period of heavy bombardment of the inner solar system, about 3.5 billion years ago, and warmed the surface, keeping it above the freezing point of water for periods ranging from decades to millennia, depending on impactor size.
Atmospheric loss since the onset of the Martian geologic record: Combined role of impact erosion and sputtering
Chemical and geomorphic evidence suggests that Mars' atmosphere has undergone significant loss or modification since the onset of the Martian geologic record. Analyses of proposed loss processes have
A Sulfur Dioxide Climate Feedback on Early Mars
TLDR
It is proposed that climatic conditions enabling the existence of liquid water were maintained by appreciable atmospheric concentrations of volcanically degassed SO2 and H2S, and geochemistry resulting from equilibration of this atmosphere with the hydrological cycle is shown to inhibit the formation of carbonates.
