Key findings
Twelve findings carry the global baseline. They are grouped by system and never ranked. Each resolves to its source or, where Nexus analysis is involved, to its stated method.

2.1Headline finding
ReportedEQL 4NRF-GLOBAL-SYSTEMS-2026-BASELINE-FIN-003
Insurers covered about 48% of the US$224 billion in natural-disaster losses in 2025, about 70% in North America, about half in Europe, about 12% in Asia and under a fifth in Africa.
| Item | Bar, scaled to the largest value | Value |
|---|---|---|
| Insured | 108 | |
| Uninsured | 116 |
Source: Munich Re NatCatSERVICE 20252; the uninsured share is the difference between overall and insured losses.
Implication
The protection gap is widest where exposure is growing fastest and fiscal space is thinnest. Uninsured losses become household debt, delayed reconstruction and pressure on public budgets, which feed back into vulnerability before the next event21318.
What would move it
Regional loss splits by peril (agenda item G-02), the growth of sovereign and parametric cover, and the 2026 and 2027 loss years would each move this finding.
2.2Climate forcing
ReportedEQL 5NRF-GLOBAL-SYSTEMS-2026-BASELINE-CLI-001
Global temperature was 1.43 ± 0.13 °C above 1850–1900 in 2025, after a record 1.55 °C in 2024; 2015–2025 are the eleven warmest years.1.
ReportedEQL 3NRF-GLOBAL-SYSTEMS-2026-BASELINE-CLI-010
Six of nine planetary boundaries were assessed as transgressed in 2023, and five major tipping systems are at risk at current warming.2021.
2.3Finance
ReportedEQL 4NRF-GLOBAL-SYSTEMS-2026-BASELINE-FIN-002
Natural disasters caused US$224 billion in losses in 2025, of which US$108 billion (48%) was insured.2.
ReportedEQL 4NRF-GLOBAL-SYSTEMS-2026-BASELINE-FIN-003
Insured shares differ sharply by region: about 70% in North America, about half in Europe, about 12% in Asia and under a fifth in Africa (2025).2.
ReportedEQL 4NRF-GLOBAL-SYSTEMS-2026-BASELINE-FIN-011
Public debt reached US$102 trillion in 2024; 3.4 billion people live in countries that spend more on interest than on health or education.13.
2.4Energy
ReportedEQL 5NRF-GLOBAL-SYSTEMS-2026-BASELINE-ENE-004
Energy-related CO₂ emissions reached a record 37.8 Gt in 2024; total greenhouse-gas emissions were 57.1 Gt CO₂e in 2023.34.
ReportedEQL 3NRF-GLOBAL-SYSTEMS-2026-BASELINE-ENE-005
Data centres used about 415 TWh of electricity in 2024, about 1.5% of the world total, with use projected to roughly double by 2030.5.
2.5Food
ReportedEQL 4NRF-GLOBAL-SYSTEMS-2026-BASELINE-FOO-006
About 673 million people faced hunger in 2024, and 2.3 billion were moderately or severely food insecure.7.
2.6Water
ReportedEQL 4NRF-GLOBAL-SYSTEMS-2026-BASELINE-WAT-007
2.2 billion people lacked safely managed drinking water and 3.5 billion lacked safely managed sanitation in 2022.8.
2.7Health
ReportedEQL 4NRF-GLOBAL-SYSTEMS-2026-BASELINE-HLT-008
Ambient and household air pollution together cause about 6.7 million deaths a year.14.
2.8Biodiversity
ReportedEQL 4NRF-GLOBAL-SYSTEMS-2026-BASELINE-BIO-009
Monitored wildlife populations declined by 73% on average between 1970 and 2020; 17.6% of land and 8.4% of the ocean are protected.910.
2.9Systemic
Expert inputEQL 2NRF-GLOBAL-SYSTEMS-2026-BASELINE-SYS-012
The leading compound pathway for 2027 testing is a concurrent breadbasket shortfall coinciding with an energy and fertiliser price shock. § scenario.
