The Consequences of Marine Heatwaves

In 2022, scientist and diver Nathaniel Bensoussan experienced a striking phenomenon during a dive. He witnessed the direct consequences of marine heatwaves on underwater ecosystems. These events, linked to climate change, cause what could be called 'underwater fires,' destroying entire habitats and threatening marine biodiversity.

The Consequences of Marine Heatwaves

Marine heatwaves are prolonged periods of elevated water temperatures, often exceeding seasonal averages. These events can be as devastating to marine ecosystems as terrestrial forest fires. Gorgonians and seagrasses, sessile marine species, are particularly vulnerable to temperature changes. When the water heats up, these organisms experience intense thermal stress, leading to their decline and death.
