The ocean is a “climate regulator” for the planet. Over the last 50 years, it has absorbed 93% of the excess heat on earth, thus limiting the warming of the atmosphere.
However, this has been at the cost of significant consequences on its chemical and physical processes, including warming, acidification, deoxygenation, and rising sea levels.
The ocean offers different solutions to limit global warming, which researchers have categorised as Decisive, Low Regret, Unproven and Risky.
While the Decisive and Low Regret measures are clearly priorities for action, they will not be sufficient. Scientific research must continue to explore the field of Unproven solutions and to understand the application conditions of Risky solutions.
