2024 Confirmed as Earth's Hottest Year on Record, First Full Calendar Year Above 1.5°C Threshold
Six independent scientific monitoring agencies — including NASA, NOAA, Copernicus, WMO, and Berkeley Earth — independently confirmed 2024 as Earth's warmest year since recordkeeping began in the 1850s. Global average surface temperature reached approximately 1.55°C above the 1850–1900 pre-industrial baseline, the first full calendar year to breach the 1.5°C level referenced in the Paris Agreement. The previous record, set in 2023, was surpassed by a margin of roughly 0.10°C — an exceptional gap in a metric that typically advances by hundredths of a degree.
claim: 2024 was Earth's hottest year in recorded history, with global average surface temperature reaching approximately 1.55°C above pre-industrial levels — the first full calendar year to exceed 1.5°C.

Findings
- All six major global temperature datasets independently placed 2024 as the warmest year since instrumental records began in the 1850s, eliminating ambiguity about the ranking.
- Global average surface temperature reached approximately 1.55°C above pre-industrial levels (1850–1900 baseline) — the first calendar year to exceed the 1.5°C threshold referenced in the 2015 Paris Agreement.
- The 2024 record surpassed 2023 by approximately 0.10°C (0.18°F), an unusually wide margin for a year-over-year record in this metric.
- Every year in the past decade now ranks among the ten warmest on record, confirming an accelerating trend rather than a statistical outlier.
- For 16 consecutive months from June 2023 through September 2024, global monthly mean temperatures set new records for their respective calendar months.
Environmental compliance teams, sustainability report authors, and climate risk analysts need a single verified reference point to anchor annual climate disclosures — UVRN provides cross-agency consensus validation with a signed receipt suitable for formal reporting.
