Study Warns Deadly , Ocean Upswells Increasing , Due to Climate Crisis.<br />'The Guardian' reports that a new study highlights how <br />the climate-disrupted ocean has pushed a number of aquatic <br />species to flee increasing temperatures in the tropics.<br />The forced migration has increasingly resulted in <br />sharks, rays and other species dying amid intense <br />upswells of cold water from the depths of the ocean.<br />In 2021, extreme cold upswelling off of <br />South Africa's coast caused a mass die-off of over <br />260 marine organisms from 81 different species.<br />A recent study found that these <br />upswellings are increasing in <br />both frequency and intensity. .<br />Scientists were able to study the 2021 <br />mass die-off in precise detail, due to one of <br />the victims being a satellite-tagged bull shark.<br />The bull shark died in waters 10 degrees <br />Celsius below the temperature <br />tropical species are accustomed to.<br />Despite the shark's attempts to avoid the <br />cold swell, it could not escape the impacted <br />area before succumbing to hypothermia.<br />'The Guardian' reports that the team found <br />that the frequency of these cold upswelling <br />events has been increasing since 1981.<br />Other species killed in similar events <br />include whale sharks, bigeye trevallies, convict <br />surgeonfish and the common blacktip shark. .<br />Other species killed in similar events <br />include whale sharks, bigeye trevallies, convict <br />surgeonfish and the common blacktip shark. .<br />Other species killed in similar events <br />include whale sharks, bigeye trevallies, convict <br />surgeonfish and the common blacktip shark. .<br />Other species killed in similar events <br />include whale sharks, bigeye trevallies, convict <br />surgeonfish and the common blacktip shark. .<br />The team's findings were published <br />on April 15 in 'Nature Climate Change.'
