Oceans Heatwaves Are Just Like Wildfire But Underwater

The oceans of our planet are affected by the so-called “ocean heatwaves” that have increased sharply and, according to the scientists, the swathes of sea-life are killed by them like “wildfires that take out huge areas of the forest.”

The humanity is also harmed by the damage caused in these hotspots because we rely on the oceans for food, storm protection, oxygen and the removal of the carbon dioxide from the atmosphere that make the climate warm faster than ever.

The average temperature of the oceans is gradually increasing due to global warming, but the first systematic, comprehensive analysis of ocean heatwaves took place in this new research. It is a phenomenon that consists of temperatures reaching extremes for five days or more.

Ocean Heatwaves Kill The Marine Flora And Fauna, Making The Future Look Gloomy

Ocean heatwaves are becoming more and more prolonged, frequent and severe, as researchers say, and, in the last couple of years, the number of days with heatwaves considerably increased. To be more precise, the number of heatwave days have jumped in 30 years to 2016 by more than 50%, compared with previous periods such as 1925 to 1954.

Seagrass meadows, kelp forests and coral reefs have been lost as ocean heatwaves have increased. The disappearance of these species of marine fauna and flora is terrible news for the sea creatures that rely on them for food and shelter. Unfortunately, that has been happening for a while, and scientists are not sure for how long it will still be going.

According to the professional who led the research that got published in Nature Climate Change, Dan Smale at the Marine Biological Association in Plymouth, in the UK, “you have heatwave-induced wildfires that take out huge areas of forest, but this is happening underwater as well. You see the kelp and seagrasses dying in front of you. Within weeks or months, they are just gone, along hundreds of kilometers of coastline.”
