Draft, not yet released. In stewardship review. Not indexed until the first approved release.

Readings from the other desks

The global baseline is read through each steward’s lens, then once as a whole. Each lens is a projection of reviewed findings, not a separate argument. The other desks’ own editions of this subject are listed first, as cross-references, not copies.

6.1The other desks’ editions of this subject

Federation: each desk writes its own edition for the subjects in its remit. Until a desk releases, its edition shows its frame and the reading this edition printed for it.

6.2Three lenses

One edition, read by each steward. The lens of this site comes first.

GCRI · KEY T

Technical Truth

The evidence supports reading the Earth system as one linked system. Seven of nine boundaries are beyond their limits, warming is near the threshold range for reefs and ice sheets, and studies disagree on the Atlantic circulation. Evidence is strongest for boundary status and weakest for interactions between boundaries.

SYS-001 · CLI-005 · CLI-007 · SYS-012

GRF · KEY M

Public Meaning

For most people the signs arrive as hotter years, bleached reefs, shifting rain and thinner harvests. The baseline asks that public debate treat the Earth system as shared and linked, and keep thresholds, not only averages, in view.

CLI-002 · CLI-005 · BIO-009

GRA · KEY F

Capital Meaning

Readiness implications only. Projected warming of 2.3 to 2.8 degrees C by 2100 and threshold risks bear on long-term asset and credit risk. These show where finance-readiness evidence will matter. Nothing here is advice, a rating or an approval.

CLI-004 · CLI-006

NEXUS

Synthesis

Earth-system risk is well described boundary by boundary and thinly measured as a system. The 2027 programme should bind interaction strengths, resolve the ocean circulation disagreement and test the compound pathway.

6.3Standards, Academy and steward contributions

How the Nexus Standards drafts, the Risk Academy and the three stewards feed each quarterly edition for planetary boundaries. The standards are a preparatory working draft (2026) and are cited as drafts, never as adopted standards.

Table 6.1The quarterly rhythm every edition follows

6.4GCRI reading: the model card

GCRI’s reading of this edition is its model card: what the national model is, what it computes and where it stops. It is printed in full in Annex A, with the methods it belongs to. Annex A, methodology

6.5Global Risks Forum reading: editorial essays

Four signed essays by the Reports editorial team set out the positions this edition takes. They are interpretation, labelled as such; the evidence they draw on is in the findings register.

Each boundary has its own control variable, but the processes share causes and feed one another. Reading them together shows pressure that single-topic reporting misses. This edition reads the system.

EDITORIAL ESSAY · 01

Boundaries are one system

Tipping assessments give central estimates with wide ranges, and observation now confirms one case. Ranges guide risk screening. They do not forecast a date, and studies still disagree on several elements.

EDITORIAL ESSAY · 02

Thresholds are ranges, not dates

Three studies of the Atlantic circulation reach different conclusions with different methods. The baseline reports all three and treats the disagreement as a gap to close with better records.

EDITORIAL ESSAY · 03

Disagreement is part of the evidence

Safe and just boundaries show that limits set by fairness can be stricter than limits set by stability. The burden of exceedance falls unevenly across people and regions.

EDITORIAL ESSAY · 04

Justice sets the limit as often as safety

  • The 2023 to 2025 average temperature passed 1.5 degrees C8
  • The Emissions Gap Report 2025 lowered projected warming on new pledges to 2.3 to 2.5 degrees C14

To watch in 2027

  • Implementation of the 2030 conservation and restoration targets27
