Oceans, warmer than before - According to Copernicus, the average global

On August 22, the oceans were warmer than ever before, since measurements began in 1979. According to data from the EU Copernicus program, the average global temperature of the seas and oceans reached 21.1 degrees Celsius.

Climate researchers were particularly surprised by the timing of the record. Sea and ocean temperatures around the world are usually highest in March and April, after the southern hemisphere summer. The previous record of 21.09 degrees was recorded in March 2024.

The new record value follows a series of monthly records that have been measured this year. According to experts, the new record is largely a consequence of global warming caused by greenhouse gas emissions, especially from the burning of oil, natural gas and coal.

Temperatures are rising even further due to the El Niño climate phenomenon in the Pacific Ocean, which occurs every few years and causes particularly high temperatures in tropical regions.

The new temperature record is another sign that the oceans are increasingly under pressure. As temperatures in the seas and oceans rise, so do the risks to coastal residents and ecosystems. One of the consequences is the destruction of coral reefs around the world, which is considered a climate tipping point. Science has been warning about this danger for years.

According to Copernicus, higher ocean and sea temperatures also increase the risk of extreme weather events. A warmer ocean releases more heat and moisture into the atmosphere, which can cause heavier rainfall and more powerful storms. It can also absorb CO₂ from the atmosphere less efficiently, thus weakening one of the most important natural defense mechanisms against climate change.
