Weekly strategic intelligence on Earth system risk, planetary boundary status, tipping points, and geopolitical cascades from environmental stress. Published every Saturday.
The Petermann Glacier calving event, combined with two further actively propagating rifts, indicates the glacier has entered a phase of accelerated dynamical instability distinct from its relative sta
Read briefing →The Amazon rainforest dieback threshold has been mechanistically lowered by deforestation to within the Paris Agreement temperature range, materially narrowing the safety margin between current warmin
Read briefing →AMOC weakening trajectory is reinforced by new Tier 1 evidence showing Nordic Seas Overturning Circulation strengthening as a physical symptom of weakening rather than a counter-signal, raising confid
Read briefing →Deforestation now functions as a co-equal driver alongside global temperature in determining Amazon tipping risk, lowering the effective collapse threshold to as little as 1.5 to 1.9 degrees Celsius u
Read briefing →West Antarctic ice-sheet sea-level-rise commitments are being revised substantially upward as ice-fracture dynamics are incorporated into modeling, indicating prior projections understated long-horizo
Read briefing →The confirmed strengthening of El Nino into a strong event for July through September 2026 raises multi-region food security and water stress risk across the Maritime Continent, southern Asia, the Car

Read briefing →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
