What ice? Looks like a vast expanse of sand. Palm trees off in the distant horizon? Posit these to our pals:

1. Define the “correct” temperature range for the planet.

2. Define the “correct” humidity range for the planet.

3. Define the “correct” mean sea level for the planet.

4. Define the “correct” amount of precipitation for the planet.

5. Define the “correct” makeup of the atmosphere.

6. Define the “correct” amount of sea ice at the N/S poles.

7. Define/explain past glaciation and subsequent warming without any input from humans.

We’ll wait..............
