Dependencies
What this concept builds on and what it makes possible — derived from the atlas’s dependency, causal and structural relations, not from every related edge.
Enables · leads to
Fossil fuelscausesCarbon dioxide (CO₂)Established
Burning fossil fuels releases carbon dioxide.
Mechanism: Combustion of hydrocarbons combines their carbon with oxygen, emitting CO₂ that photosynthesis had stored long ago.
- IPCC Sixth Assessment Report, Working Group I (Physical Science Basis) — demonstrates this case · needs-check · strong evidence · Fossil-fuel combustion is the dominant driver of the observed rise in atmospheric CO₂. (5 — Global Carbon and other Biogeochemical Cycles and Feedbacks)
Structural role & consequence
Interpreted from the current atlas graph — what the connections mean, not just how many there are.
Directly enables 1 concept; following enables/causes relations, 1 concept is downstream across 2 disciplines.
structural · Follows only enables/causes dependency edges — not general relatedness.
Currently dark in the atlas: no verified source · no key date stored.
atlas representation · Describes the current Thinking OS representation, not the state of the world.
Structural neighbourhood: 1 → 7 → 51 concepts reachable within 3 hops.
structural · Structural reach — being reachable is not the same as being understood.
All 1 of its relationships stay within its own discipline — a field-specific concept in the current atlas.
structural · Structural graph analysis — not a claim of importance, causation or history.

Strengths & constraints
Constraints
- Evidence coverage currently thin in the atlas — few of its relationships carry claim-level evidence. atlas representation
- No dated history stored — the atlas records no key date for this concept. atlas representation

Seen through each discipline
How this concept sits in each of its fields — derived from its real connections in the graph, not asserted.
Through this lens it connects to Carbon dioxide (CO₂).
Through this lens it connects to Carbon dioxide (CO₂).
What it looks like
Concrete cases that make this idea recognisable in the real world.
Ancient sunlight in a tank of petrol
The petrol in a car is energy from sunlight that plants and plankton captured millions of years ago. Burning it returns that ancient carbon to today’s atmosphere as CO₂.

Pilot slice: mapped to selected official objectives, not a coverage claim. Concept identity is canonical and never redefined by a curriculum.
Fossil fuels are the remains of living things from millions of years ago. They store carbon that photosynthesis once removed from the air. Burning them returns that carbon to the atmosphere as CO₂.
