The decade 2026–2035 will be the warmest on record globally, as measured by the WMO/NASA/NOAA combined dataset
Following the WMO's 2025 report of record heat-trapping greenhouse gas levels and the continuation of a trend in which the 11 warmest years on record occurred between 2015 and 2025, climate models project persistent warming driven by anthropogenic emissions. The decadal average global temperature anomaly for 2026–2035 is expected to exceed that of 2016–2025 with high confidence.
The US-Iran war drives cascading global crises: Hormuz blockade sustains oil above $112 and rising toward $120, IEA-reported damage to 40+ energy sites portends major Gulf marine pollution, Iranian cyber threats target critical infrastructure, while Ukrainian drone escalation forces Russia toward emergency measures near St. Petersburg.
I assess P=0.92, higher than the analyst's 0.85 and the Skeptic's adjusted 0.85, based on extremely strong base-rate evidence and physical fundamentals. Every decade since the 1980s has been warmer than the one before it, giving a base rate of 100% over four consecutive decades. Current atmospheric CO₂ exceeds 425 ppm with annual increases of ~2.5 ppm; there is no plausible pathway to a sudden emissions reversal within this timeframe. The Skeptic's critique raised volcanic eruptions, aerosol shifts, and unexpectedly sharp mitigation as counterarguments. I address each: (1) A Pinatubo-scale eruption (VEI 6+) causing multi-year global cooling occurs roughly once per 50–100 years; even if one occurred, the cooling effect (~0.3°C for 1–2 years) would likely be insufficient to offset a full decade of warming against a +1.2°C baseline trend. (2) Aerosol-shipping regulations actually reduce cooling aerosols, which would accelerate warming. (3) No current policy trajectory achieves net-zero before 2035. The Skeptic also noted ENSO variability, but at decadal scale ENSO averages out. I accept the Skeptic's suggestion to focus the claim tightly on temperature records rather than bundling in extreme weather frequency, which is harder to measure. Resolution: the 2026–2035 decadal mean global temperature anomaly (NASA GISTEMP or NOAA NOAAGlobalTemp) exceeds the 2016–2025 mean.
