The US Oceanographic Administration has just established that the average temperature at the surface of the oceans has exceeded the average temperature of the 20th century by 0.83°C.
But what is a sea heat wave and what are the consequences for the environment? We talk about it in franceinfo junior this Wednesday with CM1-CM2 students from the Jeanne Kaës school in Beaumont-Saint-Cyr, in Vienne. To answer their questions: Jean-Baptiste Sallée, oceanographer and climatologist at the National Center for Scientific Research (CNRS).

It is the children who play the interviewers on Wednesday July 5th. The first question comes back to the origins of this phenomenon: “How does a sea heat wave form?”, first wants to know Sarah. “How many kilometers deep does this take place?”, continues Maely. “Does the sea heat wave happen every year?”, “Can it cause tsunamis?”, worry in turn Lalie and Paul.
It’s Ruben’s turn to ask a question about the consequences of heat waves on wildlife: “Which animals could migrate or disappear because of these heat waves?”, asks the student.
