SO 2 has also been one of the proposed effective greenhouse gases in the early history of Mars. [48] [49] [50] However, other studies suggested that high solubility of SO 2, efficient formation of H 2 SO 4 aerosol and surface deposition prohibit the long-term build-up of SO 2 in the Martian atmosphere, and hence reduce the potential warming ...
Because its atmosphere consists mainly of CO 2, a known greenhouse gas, once Mars begins to heat, the CO 2 may help to keep thermal energy near the surface. Moreover, as it heats, more CO 2 should enter the atmosphere from the frozen reserves on the poles, enhancing the greenhouse effect. This means that the two processes of building the ...
The idea would be to augment the natural greenhouse effect on Mars to raise its surface temperature by roughly 50 degrees Fahrenheit (28 degrees Celsius) over a span of a decade.

Gas in an atmosphere with certain absorption characteristics This article is about the physical properties of greenhouse gases. For how human activities are adding to greenhouse gases, see Greenhouse gas emissions. Greenhouse gases trap some of the heat that results when sunlight heats ...
Terraforming Mars would entail two major interlaced changes: building the atmosphere and heating it. [40] A thicker atmosphere of greenhouse gases such as carbon dioxide would trap incoming solar radiation. Because the raised temperature would add greenhouse gases to the atmosphere, the two processes would augment each other. [41]
Carbon dioxide is a greenhouse gas that raises a planet's temperature: it traps heat by absorbing infrared radiation. Thus, Tharsis volcanoes, by giving off CO 2, could have made Mars more Earth-like in the past. Mars may have once had a much thicker and warmer atmosphere, and oceans or lakes may have been present.

Early greenhouse gases came from Mars' early magma, planetesimals and comets. The carbonate catastrophe ended the Noachian time span. Mars' interior cooled, so it did not develop plate tectonics and a carbon cycle as Earth did. Thus, Earth did not develop a carbonate catastrophe. Mars' interior cooling also ended volcano activity on Mars. [1 ...
An increase in temperature from greenhouse gases leading to increased water vapor (which is itself a greenhouse gas) causing further warming is a positive feedback, but not a runaway effect, on Earth. [13] Positive feedback effects are common (e.g. ice–albedo feedback) but runaway effects do not necessarily emerge from their presence.
