The planet in deep time
Earth science studies the planet itself — its rocks, oceans, atmosphere, and the deep-time story written in them. It reveals both Earth's four-and-a-half-billion-year past and the climate future we are now, unavoidably, helping to write.
One honesty note up front, because it matters: the basic science of human-caused climate change is settled. The genuine scientific debates are about magnitude and specifics, not whether it's happening. Set your level below.

Rock, ocean, air, and deep timeThe planet studied as a set of interacting systems.
- Geology & Earth structure — rocks, plate tectonics, and how the planet is built.
- Palaeontology — life's history, read from the fossil record.
- Oceanography — the oceans that drive climate and cover most of the world.
- Atmospheric science & meteorology — weather and the air.
- Climate science & Earth systems — how it all fits together, over time.
- Environmental science & hazards — pollution, resilience, earthquakes and floods.
The canon
The scientists who read the rocksReal figures, real ideas.
- James Hutton (18th c.) — deep time, and the dizzying idea of "no vestige of a beginning."
- Charles Lyell — Principles of Geology, which shaped Darwin as much as any biologist.
- Alfred Wegener (1912) — proposed continental drift, was rejected for decades, and was right.
- The plate tectonics revolution (1960s) — finally explained the shape and behaviour of the whole Earth.
- Milutin Milanković — orbital cycles that help drive the ice ages.
- Charles Keeling — the "Keeling Curve," the continuous record of rising atmospheric CO₂.
The live debates
Debates within a settled scienceThe consensus is firm; the frontier is about the details.
- Climate sensitivity and tipping points. How much warming per unit of CO₂, and where irreversible thresholds lie — real uncertainty, inside a settled picture.
- Geoengineering. Whether to deliberately intervene in the climate, and the enormous risks of doing so.
- Reading the deep-time record. How to interpret an incomplete rock and fossil archive.
- Predicting hazards. Why earthquakes, in particular, resist prediction.
- The Anthropocene. Whether human impact warrants a new formal geological epoch.
Where to start
A route inA route in — everything runs from the panel above.
- Run Orientation on plate tectonics (the key that unlocks geology) or on the climate system.
- Sit with Hutton's deep time via the Socratic tutor — it genuinely rewires your sense of scale.
- Use Real-World Applications on climate or natural hazards.
- Read a good Earth-science book alongside the primary climate data.
Deep time is the great lesson here: the Earth is old, patient, and far larger than us.
