**What was analyzed:** The article presents data regarding the achievement of a new record temperature at the ocean surface on June 21, 2026, citing the Copernicus service and various climate experts, in the context of the heatwave in Europe. **What the sources confirm:** Recent sources (The Guardian, Copernicus, WMO) confirm that on June 21, 2026, a historic record of ocean surface temperatures was recorded, surpassing the values from 2023 and 2024. The statements of the Copernicus director, Carlo Buontempo, and the context of the extreme heatwave in Europe and Romania are also confirmed. **Limitations:** Certain specific percentages attributed to UN estimates (91% and 86%) and the statements of climatologist Friederike Otto could not be directly verified from the sources available in the dataset. **Conclusion:** The article is largely correct and based on real and recent scientific data, with minor secondary statistical details remaining unverified due to source limitations.

Recommended next steps
- Consult the official website of the World Meteorological Organization (WMO) or the UN for reports on the 1.5°C threshold.
- Look for recent interviews with climatologist Friederike Otto from June/July 2026.
Analysis limitations
- The exact percentages from the UN (91% and 86%) could not be verified due to the absence of specific UN reports in the provided sources.
- The statements of climatologist Friederike Otto are not covered by the sources in the database.
- Some initially cited evidence could not be validated against the downloaded sources and was removed; the affected claims have been marked UNVERIFIED.
- Providing an official UN/WMO report from 2026 that certifies the probabilities of 91% and 86%.
