Weekly strategic intelligence on Earth system risk, planetary boundary status, tipping points, and geopolitical cascades from environmental stress. Published every Saturday.
Sustained three-month record heat sequence (May to July 2026) combined with a lowered Amazon degradation threshold indicates the climate change and land-system change boundaries are now interacting no
Read briefing →The Nordic Seas Overturning Circulation strengthening is confirmed by PIK to be a symptom of AMOC weakening rather than a stabilising counter-signal, and may itself be a precursor to eventual collapse
Read briefing →El Niño onset in context of already-elevated baseline SST represents non-linear acceleration of climate change boundary rather than discrete crossing; super El Niño trajectory by September will compou
Read briefing →The June 2026 European heatwave represents a structural threshold in climate risk manifestation: formal attribution confirms the event was virtually impossible without anthropogenic forcing, and polit
Read briefing →The 1.5°C carbon budget exhaustion timeline of approximately 3 years at current emission rates creates acute pressure on NDC compliance cycles and compresses adaptation windows for climate-fragile sta

Read briefing →AMOC slowdown has entered structural lock-in phase where enhanced North Atlantic salinity variability persists even under climate mitigation because ocean circulation recovers slowly, creating irrever

Read briefing →AMOC weakening trajectory has materially accelerated with two independent Tier 1 papers in 2026 tightening risk envelope by 60 percent stronger weakening projection than model-only estimates; observat
