Evolutionist belief that the steep slopes on Mars have gullies with morphologies suggesting that they were formed by a fluid, But the mechanisms involving carbon dioxide ice do not explain the distribution of the gullies.

Now, Dickson et al. simulated how the climate of Mars differed when its axis tilted by different amounts over the past evolution’ s few million years. In their view,  at a tilt of 35 degrees, the ice caps partially melted, raising the atmospheric pressure,. As a result, it resulted in higher summer temperatures, and water could form so that it would melt to form a liquid.
