Mentioning the Earth’s climate cycle is relative to Mars only in the sense that planets can have cycles. Earth’s current warming is still unknown as its relation to ocean currents and the ability for the oceans to mitigate higher CO2 levels.
To speculate on Mars climate cycles we must find heat and water. Solar intensity due to angle or change in orbit is the primary source with any residual geologic activity secondary. The discovery of abundant vapor emissions from the scarp would increase water vapor levels and increase temperature because water is one of the greatest green house gases.
It would seem to me that any condition can have many potential causes with the etiology limited only to the ability of the speculator.
