„Wanderers“ is my short science fiction film envisioning our humanity‘s future expansion into the Solar System. Although admittedly speculative, the visuals in the film are all based on scientific ideas and concepts of what our future in space might look like, if it ever happens.
All the locations depicted in the film are digital recreations of actual places in the Solar System, built from real photos and map data where available.

Earth and Mars: Evolution of Atmospheres and Surface Temperatures
(7. Juli 1972)
Indeed, detailed global climatic models (17) suggest that a relative increase in A of only 2 percent is enough to induce extensive glaciation on Earth, which implies that the present climate is extremely sensitive to albedo. This leaves changes in atmospheric composition as a possible explanation. Major variations in the CO2 abundance will have only minor greenhouse effects because the strongest bands are nearly saturated. A change in the present CO2 abundance by a factor of 2 will produce directly a 2° variation in surface temperature (18). The CO2 abundance is highly controlled by silicate-carbonate equilibria; by buffering with seawater, which contains almost 100 times the atmospheric CO2; and by the respiration and photosynthesis feedback loop (19).
