HOW IT WORKS
Every number comes from a verified public source. Composite indices publish every

WORLD ON EDGE INDEXFive inputs normalized 0–100, weighted and summed. GPR (35%): Caldara & Iacoviello index vs 0–200 range. ACLED (25%): active conflict zones vs 0–80 range. Gallup (15%): worry index as published. Conflict Deaths (15%): YTD deaths vs 50,000 threshold. Species Threat (10%): threatened % vs 50% threshold. Weights at anthonycharts.com/composites-v1.0.json
WORLD GOODNESS INDEXSix inputs normalized 0–100, weighted and summed. Aid (20%): OCHA commitments vs 30B USD. Poverty (20%): World Bank rate inverted. Breakthroughs (15%): OWID annual count vs 50. Treaties (15%): UN quarterly signatures vs 30. Social Mobility (15%): World Bank GSMI 0–100. Conservation (15%): % of 30x30 target achieved. Weights at anthonycharts.com/composites-v1.0.json
GLOBAL TEMP ANOMALY12-month trailing average of global surface temperature anomaly above 1850–1900 pre-industrial mean. Primary: Copernicus C3S ERA5 reanalysis. Cross-referenced with NOAA GISSTEMP and Berkeley Earth. Arc = position in 0–2°C Paris risk corridor. Updated monthly.
SEA LEVEL RISEContinuous satellite altimetry: TOPEX/Poseidon (1993) → Jason-1/2/3 → Sentinel-6 Michael Freilich (2020–present). Monthly global mean averages from NASA JPL Physical Oceanography DAAC. Arc = position in 0–200mm scale. Rate acceleration from linear trend analysis of 5-year segments.
ARCTIC SEA ICE EXTENTNSIDC Sea Ice Index via satellite passive microwave (SMMR, SSM/I, SSMIS). Extent = total ocean area with at least 15% ice concentration. Updated daily. Compared against 1981–2010 median for the same calendar day to remove seasonal signal. Arc = percentile within seasonal historical range.
CO₂ CONCENTRATIONContinuous measurement at NOAA Mauna Loa Observatory since 1958 (the Keeling Curve). Weekly averages from NOAA Global Monitoring Laboratory. Cross-referenced with Scripps Institution CO₂ program. Arc = position between 280ppm (pre-industrial) and 500ppm (extreme risk ceiling).
EXOPLANET DISCOVERYRaw count from NASA Exoplanet Archive. Confirmed status requires: peer-reviewed publication, independent verification via secondary detection method, and archive acceptance. Habitable zone defined by orbital distance allowing liquid surface water. Arc = pace toward 10,000 milestone by 2030.
TECHNOSIGNATURE WATCHManual count from Breakthrough Listen published candidate reports and SETI Institute announcements. Candidate criteria: passed RFI filtering, observed in multiple independent beams, no confirmed natural explanation at time of logging. Updated as reported in peer-reviewed publications.
SOLAR ACTIVITY24-hour peak geomagnetic storm rating from NOAA Space Weather Prediction Center (SWPC). G-scale from Kp-index: G1=Kp≥5, G2=Kp≥6, G3=Kp≥7, G4=Kp≥8, G5=Kp=9. Sunspot number from WDC-SILSO, Royal Observatory of Belgium — international standard since 1849.
NEAR-EARTH OBJECT WATCHNASA CNEOS close approach database. Close approach = within 0.05 AU (~7.5M km). Impact probability from JPL Sentry automated orbital mechanics. Potentially hazardous: >140m + intersects within 0.05 AU. Updated daily from automated telescope observations worldwide.
WEALTH INEQUALITYGlobal Gini from World Inequality Database (WID.world) — maintained by Piketty, Chancel, Saez, and Zucman. Gini: 0 = perfect equality, 1 = perfect inequality. Arc normalized against 0–1.0 scale, with 0.8 as practical ceiling. Updated annually with World Inequality Report.
SOCIAL MOBILITY INDEXWorld Bank GSMI: 10 equal-weight pillars — health, education access, education quality, lifelong learning, technology access, work opportunities, fair wages, working conditions, social protection, institutions. Supplemented by Opportunity Insights intergenerational income mobility data. Annual publication.
CONFLICT DEATHSPrimary: ACLED — real-time coding of political violence events from media, NGOs, and government sources across 200+ countries. Cross-referenced with UCDP (Uppsala Conflict Data Program) for battle death estimates. Battle deaths only — excludes indirect deaths from displacement or disease. Updated monthly.
PEACEKEEPING REACHUN DPPA monthly fact sheets. Personnel = troops + police + civilian international/national staff. Budget from UN General Assembly appropriations. Mission count = active mandated operations. Updated monthly from official UN reporting.
SPECIES THREAT INDEXIUCN Red List — the world's most comprehensive biodiversity database. Assessed across nine categories from Least Concern to Extinct. Threatened = Vulnerable + Endangered + Critically Endangered. Updated quarterly. Arc = threatened % of assessed, normalized against 50% ceiling.
CONSERVATION COVERAGEProtected Planet database by UNEP-WCMC and IUCN. Counts nationally designated protected areas and OECMs (Other Effective Area-Based Conservation Measures). Updated annually with country submissions to the Convention on Biological Diversity. Arc = % of 30x30 land target achieved.
GLOBAL TRADE STRESSExperimental composite: Freightos Baltic Index (35%) — global container freight benchmark normalized historically. Manufacturing PMI inverted (35%) — S&P Global composite, inverted so contraction = higher stress. World Bank trade volume momentum (30%) — month-over-month change.

INFORMATION INTEGRITY INDEXExperimental composite: IFCN claim accuracy rate (50%) — from IFCN-verified fact-checkers internationally. RSF Press Freedom Index inverted (30%) — higher freedom = higher integrity score. NewsGuard credibility average (20%) — ratings of major news and information sources. Experimental — weights subject to revision, published at anthonycharts.com/composites-v1.0.json
