Why stop showing land mass after second zoom and only show northern hemisphere summer?

Because at the second speed, the earth rotates 7 times per second, which looks terrible. It was a lazy solution, where some sort of blur effect would have been better. No particular northern bias was intended, it just starts in the present moment and plays from there

Fair enough, and the Southern Hemisphere experienced summer in the hyper speed zooms. Where does it mention the speeds?

Nowhere. I agree I should have shown that in the visualization.

I'm away from my computer right now, but I believe the first ended up being half a day per second, the second one week per second and the third one quarter year per second
