Scientists are trying to understand why the surface temperature is at an all-time high.
This is unheard of. The average temperature at the surface of the oceans has exceeded 21°C since March 12, a threshold that was fleetingly reached in 2016. « What surprises is the very significant jump compared to all previous years. Is it a short-lived extreme event or an underlying trend ? »wonders Jean-Pierre Gattuso, oceanographer and associate researcher at the Institute for Sustainable Development and International Relations (IDDRI).
In details, « the 21,1 °C of the average temperature of the “skin” of the ocean, reached at the beginning of April, is a record since the beginning of reliable satellite measurements in 1981. We are maintaining a very warm plateau »explains Thibault Guinaldo, researcher in space oceanography at Météo-France, in Lannion. « We do not yet know why there is a sharp increase in the average temperature at the surface of the oceans, which is particularly evident in the Indian and Pacific oceans. The entire scientific community is wondering…
