Core Forecast: Near-Record Heat and Accelerating Arctic Warming
The World Meteorological Organization (WMO) and the United Kingdom’s Met Office released the Global Annual-to-Decadal Update, projecting that the global annual-mean near-surface temperature for 2026-2030 will lie 1.3 °C to 1.9 °C above the 1850-1900 pre-industrial baseline. The report states it is very likely (?91 % chance) that the 1.5 °C threshold will be temporarily exceeded for at least one year in this period, and ?86 % chance that a year between 2026 and 2030 will surpass 2024 as the warmest on record. Arctic winter temperatures are expected to rise about 2.8 °C above the 1991-2020 average, more than three-and-a-half times the global mean anomaly, with March sea-ice loss projected in the Barents Sea, Bering Sea and Sea of Okhotsk.
Background & Context: WMO-Met Office Update and the Paris Agreement
The update synthesises observations from 13 institutes—including the Barcelona Supercomputing Centre, the Canadian Centre for Climate Modelling and Analysis, and Deutscher Wetterdienst—and serves as guidance for regional climate centres and national meteorological services. It follows the 2015 Paris Agreement, under which signatories pledged to keep long-term warming “well below 2 °C” and to pursue efforts to limit it to 1.5 °C.
Data & Statistics: Probabilities, Temperature Anomalies, and Precipitation Shifts
- Temperature range (2026-2030): 1.3 °C–1.9 °C above pre-industrial.
- Probability of a new record year (2026-2030): 86 % (exceeding 2024).
- Probability of a temporary 1.5 °C exceedance: 91 % (at least one year).
- Arctic winter anomaly: +2.8 °C, ?3.5 × the global mean.
- Precipitation outlook: wetter winters in northern Europe, Alaska, Siberia and the Sahel (May-Sept); drier conditions projected for the Amazon; overall increase in high-latitude and tropical winter precipitation, with declines in subtropical regions.
Official Statements & Responses: Institutional Perspectives
Melissa Seabrook, research scientist at the UK Met Office, emphasized that the evidence of ongoing warming is unequivocal and warned that the window to keep average temperatures at 1.5 °C is rapidly closing. Leon Hermanson, lead author of the report, highlighted the role of an anticipated El Niño at the end of 2026 in raising the likelihood of a record-breaking 2027. The WMO noted that the forecasts are intended to guide regional climate centres, outlook forums, and national meteorological and hydrological services.
Criticism & Opposition: Scientific Concerns About Crossing 1.5 °C
Scientists cited in the report caution that sustained warming beyond 1.5 °C “risks unleashing ever more severe climate change impacts, extreme weather and decreasing adaptation options.” These warnings underscore the urgency of mitigation efforts despite the report’s framing of temporary exceedances as not constituting a Paris-Agreement breach.
Conflicting Reports & Gaps: Probability Discrepancies and Missing Regional Detail
While most sources agree on the temperature range, the probability figures differ: the Reuters summary cites a “very likely” exceedance without a numeric value, whereas the DownToEarth and Shillong Times pieces give a 91 % chance for a 1.5 °C breach. The report provides broad precipitation trends but lacks detailed forecasts for specific sub-regional basins, leaving a gap for local adaptation planning.

- “There's very clear evidence that the climate is warming and that the global average temperature is continuing to rise,” — Melissa Seabrook, research scientist, UK Met Office
- “The science is very clear that the window to keeping the global average temperature to 1.5 degrees is closing rapidly,” — Melissa Seabrook, UK Met Office
- “There is an El Niño predicted for the end of 2026, which increases the chances of the following year, 2027, being the next record-breaking year,” — Leon Hermanson, lead author, WMO report
- “The forecasts are intended as guidance for Regional Climate Centres, Regional Climate Outlook Forums and National Meteorological and Hydrological Services,” — World Meteorological Organization statement
- “Astrong El Ninois also predicted for winter this year, which could persist into 2027, driving up global temperatures to potential record-breaking levels due to the heating of the Pacific Ocean, Seabrook said.” — Melissa Seabrook, UK Met Office
What’s Next: El Niño Outlook and Monitoring Plans
The report flags a strong El Niño developing in the central tropical Pacific (Nino 3.4 region) for late 2026, with heightened risk of a record-breaking 2027. WMO and the Met Office will update regional outlooks annually, and national services are urged to incorporate these projections into climate-risk assessments and adaptation strategies.
