The surface temperature of the world's oceans reached a historic maximum in June

The average surface temperature of the world's oceans in June 2026 was 20.98 degrees Celsius, which was a historical maximum. This was announced on July 1 by the European monitoring service Copernicus Marine.

It is noted that the previous record was set in 2024 and was 20.89 degrees. Experts attribute the rise in temperatures to global warming and the El Nino climate phenomenon.

"Given these ocean temperatures and the approaching El Nino, we are likely to see new records in the coming months," said Carlo Buontempo, director of Copernicus' climate change service.

It is also specified that the first half of 2026 was the second warmest in the history of observations, second only to the same period in 2024.

"Scientists estimated the restoration of the Mir deep-sea vehicles at 20 billion rubles."

Anna Kozachek, a researcher at the Laboratory of Climate and Environmental Change at the Arctic and Antarctic Research Institute (AARI), said on June 11 that the complete melting of all glaciers on Earth could lead to an increase in sea levels by 150 m, but such a scenario is not predicted in the coming centuries. At the same time, the expert stressed that such a catastrophic scenario should not be expected in the next few centuries.
