In complex systems under climate and conflict stress, early warnings are rarely absent. They are present — but they arrive in the wrong format, through the wrong channels, to the wrong people, at the wrong moment in the decision cycle. Or they arrive correctly and are actively filtered out by organisations that have learned, structurally, not to act on uncertain signals.
Yellow Flagging is a signal detection and early warning sub-service sitting within the Green Teaming practice. Where Green Teaming orients organisations to navigate climate complexity broadly, Yellow Flagging focuses on the front edge: the weak signals, the threshold indicators, the patterns that precede disruption — and the organisational habits that cause them to be missed.
The work is not prediction. It is perceptual discipline: training organisations to see what they are already capable of seeing, before the cost of not seeing it becomes irreversible.
Signal type 01
Climate Threshold Signals
Physical tipping indicators in operating environments — heat thresholds, water stress indices, extreme event frequency shifts — that precede supply and infrastructure disruption.
Signal type 02
Social Fracture Precursors
Early indicators of community stress, trust erosion, and distributional grievance that emerge before visible conflict — displacement pressure, livelihood instability, institutional delegitimisation.
Signal type 03
Regulatory Inflection Signals
Legislative, litigation, and policy signals that precede hard regulatory shifts — before they crystallise into obligations that organisations have no time to adapt to.
Signal type 04
Market Belief Shifts
Movements in investor sentiment, insurance withdrawal, and capital allocation that signal where market consensus on climate risk is heading — before it arrives.
Signal type 05
Competitor Repositioning
Structural moves by sector peers — supply chain reconfiguration, asset stranding, narrative pivots — that indicate where the sector believes the ground is shifting.
Signal type 06
Organisational Filter Failures
The internal signals — dissent, anomalous data, frontline intelligence — that are present in organisations but suppressed, averaged, or routed to people without authority to act on them.
