Measurements analyzed by an international research team led by ETH Zurich show that the global ocean absorbed significantly less COβ than anticipated during the unprecedented marine heat wave in 2023. The world's oceans act as an important sink for carbon dioxide (COβ). To date, they have absorbed around a quarter of human-induced COβ emissions from the atmosphere, thereby stabilizing the global climate system.
