WMO: 2015–2025 Are the 11 Warmest Years Ever Recorded
An unbroken streak of record-warm years means longer, more intense high-UV seasons — and a stronger case for daily SPF.
The WMO confirmed 2025 was one of the three warmest years on record at about 1.44°C above the 1850-1900 average, and that 2015-2025 are the 11 warmest years in all eight datasets.
The World Meteorological Organization frames an unbroken decade-plus of record warmth as evidence of a sustained climate shift, noting the consistency across all eight major temperature datasets it assessed.
Questions we get a lot
How warm was 2025 according to the WMO?
The World Meteorological Organization confirmed that 2025 was one of the three warmest years on record, at about 1.44°C above the 1850-1900 pre-industrial average. The figure draws on multiple independent global temperature datasets.
What does the 2015-2025 streak mean?
The WMO confirmed that 2015 through 2025 are the 11 warmest years on record across all eight datasets it assessed. An unbroken streak of record-warm years signals a sustained warming trend rather than year-to-year noise.
Why does this matter for sun protection?
Sustained record warmth tends to lengthen and intensify high-UV seasons, meaning more days of elevated exposure. That strengthens the case for treating broad-spectrum sunscreen as a daily, year-round essential rather than something reserved for summer.
