Is this an unprecedented climate catastrophe or are scientists manipulating the data?

The Facts

  • Global average sea surface temperatures outside polar regions reached 20.96°C in July, surpassing the previous July record of 20.89°C set in 2023, with El Niño conditions in the equatorial Pacific cited as a contributing factor.
  • The EU’s Copernicus climate change service recorded that sea surface temperatures reached record highs for July on the Atlantic coast and western Mediterranean. It also found that severe marine heatwaves had swept the seas near Europe.
  • The rising sea temperatures were partly caused by evolving El Niño conditions in the equatorial Pacific, Copernicus said. However, global surface air temperatures in July 2026 fell lower than in July 2024 by a margin of 0.01°C.

The Spin


Climate-concerned narrative

Ocean temperatures matching the 2023 all-time high aren't a coincidence; they're a compounding disaster where every time the ocean reaches that ceiling, the land-based damage gets worse. Western Europe is living through a climate catastrophe — three straight months of record heat, over 500,000 hectares burned, and major rivers running dry reveal a continent under siege.

Climate-skeptic narrative

Blaming record ocean heat on a single year's CO2 emissions is textbook energy accounting abuse. The observed 23 zettajoule increase already reflects ENSO shifts, internal variability and decades of accumulated forcing — not 2025 emissions, which could account for under 1 zettajoule at most.
