Global ocean surface temperature has reached a record-breaking level, causing heat waves.
The temperature of the ocean's top floor is at 21.1C, surpassing the earlier record of 21°C.
The current trajectory is smashing previous records, according to Prof Matthew England.
La Nina states have helped cool temperatures and reduce greenhouse gas emissions.
Heat rising to the ocean's surface reflects the possibility of an El Nino pattern later in 2022.
Oceans have absorbed 90% of the excess heat caused by greenhouse gas emissions.
La Nina cools global temperatures, while El Nino raises them.
The ocean has absorbed over 90% of excessive heat caused by the burning of fossil fuels and deforestation.
