This talk provides an overview and tour of the findings from Curiosity, featuring spectacular high definition images, tantalizing mineralogical evidence for fresh water, and atmospheric isotopic measurements indicative of an ancient climate different from today.
The research from NASA's Goddard Institute for Space Studies (GISS), published this week in the journal Geophysical Research Letters, used topographical and atmospheric data collected by the Pioneer and Magellan space probes to create 3 - D climate simulations, filling in lowlands with water and accounting for an ancient sun 30 percent dimmer than it is today.
The identified atmospheric feedbacks including changes in planetary albedo, in water vapour distribution and in meridional latent heat transport are all poorly represented in zonal energy balance model as the one used in [7] whereas they appear to be of primary importance when focusing on ancient greenhouse climates.
In short, your idea that the temperature of the earth has been remarkably stable over times is correct, and the idea that water seems to dominate also looks correct, but the idea of a stable atmospheric density appears incorrect, and the ancient sun is a complete unknown that needs looking into.
Micro bubbles found in deep polar ice cores of the ancient atmosphere (1 - 200,000 years ago) showed a higher atmospheric density than now, perhaps 2 atmospheres, also higher water vapor and CO2.
