The sea heat has been at its historic extreme for years!

By dint of hearing about it, climate change is almost a habitual phenomenon for us. Global warming is becoming a very frequent term, but we do not necessarily realize its extent. To assess the evolution of sea ​​warmingscientists have been collecting and comparing data for a century and a half.

The results showed that the ocean experienced a excessive heat since 2014 till today. The rise in sea temperature would become almost a normality. Of course, this represents a imminent danger for marine flora and fauna. We could witness the collapse of aquatic ecosystems and the extinction of several species.

We find ourselves at a time when decisions must be combined with the present and the immediate future. The drastic reduction in greenhouse gas emissions produced by human activities is a crucial necessity.

In 150 years, sea temperatures have been excessive for 7 years

Researchers from the Monterey Bay Aquarium have revealed the excessive ocean warming. This study was conducted in the California kelp forest and then extended beyond California. They performed a temperature mapping surface of the sea for a century and a half. Throughout history they have wanted determine a reference fixed for sea heat extremes.

Scientists have observed how the temperature exceeded the reference point and at what frequency. Since exactly 2014, the majority of the surface of the ocean, more precisely its half, has experienced extremes of heat. Still in relation to the benchmark set, in 2019, 57% of the ocean experienced extreme heat. Yet, towards the end of the 19th century, only 2% of the surface of the ocean experienced extreme hot temperatures.

“Today, the majority of the ocean surface has warmed to temperatures that only a century ago were considered rare extreme warming events, occurring once every 50 years. »

Action against global warming becomes an emergency

The marine ecosystems are currently exposed to extreme conditionsincreasing the risk of their collapse. Dr. Kyle Van Houtan recalled that climate change is a reality that affects us and not a future event. The dramatic changes in the ocean should spur us to action.

“When marine ecosystems near the tropics experience intolerable temperatures, key organisms such as corals, seagrass beds or kelp forests can collapse. Altering the structure and function of ecosystems threatens their ability to provide vital services to human communities, such as supporting healthy and sustainable fisheries, protecting low-lying coastal regions from extreme weather events, and the function sinks to store the excess carbon emitted into the atmosphere by human-caused greenhouse gas emissions. »
