An identical thermal anomaly occurred in the same place five years ago, causing the death of millions of marine animals.
A gigantic ocean heat wave in the Pacific off the west coast of the United States threatens to repeat the devastating effects of a similar phenomenon that was recorded in the region five years ago and killed millions of marine animals, experts warn of the National Oceanic and Atmospheric Administration (NOAA).
In 2014, an unprecedented thermal anomaly – at least from the records that have been carried out since 1981 – extended from the latitudes of the Baja California peninsula to the southern tip of Alaska.
This temperature increase persisted for several years, leading to the proliferation of toxic algae that killed more than 100 million copies of Pacific cod , as well as half a million seabirds .
In addition, the population of humpbacks was diminished by 30% in just one year, while the number of salmon , sea lions , and small crustaceans also significantly reduced, detailing the portal Science Alert.
A monstrous pattern
All this meant immeasurable damage to both ecology and industry. The destructive consequences of this phenomenon earned him even the nickname of ‘ Blob ‘, in reference to the horror film of the same name – known as ‘The voracious stain’ or ‘Terror has no form’ – on an amorphous monster that swallows everything his step.
The new heat spot has been registered a few months ago in the same location as its predecessor and seems to follow the same pattern of development , forming as the intensity of the winds that cool the surface of the water and reaching almost the same size in the course of the same time. And this disastrous similarity does not stop worrying the experts, who closely follow the phenomenon.
A growing problem
“It is on the way to becoming equally strong than the previous event,” said Andrew Leising, the author of the methodology used by NOAA to measure the intensity of ocean heat waves.
Scientists detail that the spot currently exceeds 2.8 degrees Celsius at the normal temperature for the region and is between half a degree and one degree below the predecessor. And they explain that these heat waves are able to dissipate with the same speed with which they arise, depending on complex climatic factors
However, these types of phenomena will become more frequent over time as the oceans heat up at an unprecedented rate due to the effects of global climate change.
