Real Science Fiction About 8 in 10,000 Molecules

How the escalation works

1. 1

   CO₂ concentration number

   A proportion of the atmosphere (e.g. 4 in 10,000 → 8 in 10,000).

2. 2

   radiative forcing estimate

   Physics estimate of energy imbalance from that concentration change.

3. 3

   model pathway / SSP5-8.5

   One of many modelled futures, a high-emissions stress-test pathway.

Claim-entitlement jump
From physics-based scenario to rhetorical framing of catastrophe. The model output describes one possible high-emissions future; the framing converts it into "the future" and selects high-end impacts as headline-grade.
4. 4

   headline-scale catastrophe framing

   Selection and amplification of high-end outcomes and impacts.

Claim-entitlement jump
From catastrophe framing to political mandate, treated as self-evident. The framing now licenses urgency, policy demands, and rhetorical closure — without re-auditing the physics, the scenario, or the framing itself.
5. 5

   policy urgency / apocalypse narrative

   Framing used to mobilise action, often treated as self-evident.
