Study Warns Deadly , Ocean Upswells Increasing , Due to Climate Crisis.
'The Guardian' reports that a new study highlights how
the climate-disrupted ocean has pushed a number of aquatic
species to flee increasing temperatures in the tropics.
The forced migration has increasingly resulted in
sharks, rays and other species dying amid intense
upswells of cold water from the depths of the ocean.
In 2021, extreme cold upswelling off of
South Africa's coast caused a mass die-off of over
260 marine organisms from 81 different species.
A recent study found that these
upswellings are increasing in
both frequency and intensity. .
Scientists were able to study the 2021
mass die-off in precise detail, due to one of
the victims being a satellite-tagged bull shark.
The bull shark died in waters 10 degrees
Celsius below the temperature
tropical species are accustomed to.
Despite the shark's attempts to avoid the
cold swell, it could not escape the impacted
area before succumbing to hypothermia.
'The Guardian' reports that the team found
that the frequency of these cold upswelling
events has been increasing since 1981.
Other species killed in similar events
include whale sharks, bigeye trevallies, convict
surgeonfish and the common blacktip shark. .
