The concentration of carbon dioxide
is now higher than at any other time in the last 850,000 years.

I learn about Milancovitch cycles.

These are the natural cycles
of glacial and interglacial eras.

Animating to these rhythms,
I connect with the cycles of change.

Layers and layers of data
trapped in glacial ice
and sea floor sediments,
reveal that a natural rhythm
has been upset
by massive burning of fossil fuels.
