These studies suggest Mars is cold due to its thin CO2 atmosphere, glacial features, and a climate similar to the Antarctic Dry Valleys, with transient liquid water and ice equilibrium.

Mars, often referred to as the "Red Planet," is known for its cold climate. Understanding why Mars is so cold involves examining its atmospheric composition, historical climate changes, and geological features. This synthesis aims to consolidate findings from multiple research papers to provide a comprehensive explanation for Mars' cold temperatures.
Thin Atmosphere and Limited Greenhouse Effect:
Historical Climate and Geothermal Activity:
Cold-Based Glaciation:
Geomorphological Evidence:
Saline and Acidic Liquid Solutions:
Mars is cold primarily due to its thin atmosphere, which lacks the capacity for significant greenhouse warming. Historical geothermal activity and impacts provided only transient warming, insufficient to sustain long-term warm conditions. The planet's geological features and evidence of cold-based glaciation further support the notion of a predominantly cold climate. Periods of liquid water were likely brief and driven by specific conditions, such as higher atmospheric pressure and the presence of saline and acidic solutions. Overall, Mars' cold climate is a result of its atmospheric composition, historical climate events, and geological processes.
