The oceans are very warm in June. They are warmer than ever before. Experts measured the heat on 21 June. An EU program monitors the climate. It is called Copernicus. Copernicus measured high values. One value was 20.86 degrees. The other value was 21.0 degrees. This is more than in previous years. Experts use satellites in space. They also use data from measuring stations.
Climate change is one reason for the heat. Another reason is El Niño. El Niño is a weather event. It happens every 2 to 7 years. Winds over the Pacific get weak. This makes the water very warm. El Niño makes climate change worse. It causes less rain or floods. Countries in the south notice this often. The effects are small in Europe.
Warm oceans are dangerous for the weather. Warm water makes the air warm too. The air keeps much energy. This leads to big storms and rain. Oceans are important for the world climate. They take in most of the heat. Carlo Buontempo leads Copernicus. He thinks that new records will come soon. The Earth enters a new phase of heating.
