Study: Great white sharks will be swimming in British waters by 2050
As a result of warming seas, at least 10 types of sharks currently found in warmer areas will likely be found in British waters in coming decades.
Great white sharks will likely start moving north as warming seas open new habitats for the predatory fish, according to a new study.
The study, led by Ken Collins at the University of Southampton, predicts that at least 10 types of shark currently found in warmer places, like the Mediterranean and coast of Africa, will be swimming in British waters in coming decades.
“These include the likes of blacktips, sand tigers and hammerheads, which are currently found swimming off the coasts of Spain and Portugal,” Collins said.
Collins, a Senior Research Fellow within Ocean and Earth Science, National Oceanography Centre Southampton at the University of Southampton, said the changes are the result of climate change, which poses threats to shark populations worldwide.
“Though while the potential number of shark species may increase in the next few decades, the overall number of sharks, especially the larger ones, will fall as a result of overfishing, plastic waste and climate change.”

He elaborated in an interview with The Independent:
“We will increase from 40 species to maybe 60, but there will still be less of them—and some of the existing ones will maybe go extinct in the meantime... They are getting rarer and rarer—and it’s the big sharks that have the problem because people target them.”
Shark migration patterns also seem to be changing in other parts of the world’s oceans. Earlier this year, National Geographic spoke with marine biologist Stephen Kajiura, who’s been tracking blacktip sharks for more than a decade.
“This year has been strange,” he said.
During the colder months, blacktip sharks normally swim south from North Carolina to Florida, but this year researchers noticed that only one-third of the usual number of blacktips had migrated south. They suspect the sharks are staying north because of warmer waters.
“Last year was unusually warm all winter: The water temperatures never got below 73.4 Fahrenheit,” Kajiura said. “This year, the temperatures have risen dramatically to 78.8 Fahrenheit. It’s now even hotter than this time last year.”
Sharks can disrupt marine ecosystems when they relocate or change migration patterns. An increase of sharks in a region can result in the extinction of other types of marine life, including other species of shark.
Conversely, the disappearance of sharks from an area they once inhabited, like the Florida coast, can spell disaster for coral reefs and seagrasses because sharks help keep the “ecosystem healthy by weeding out weak and sick fish,” as National Geographic reported.
Construction of the $500 billion dollar tech city-state of the future is moving ahead.
- The futuristic megacity Neom is being built in Saudi Arabia.
- The city will be fully automated, leading in health, education and quality of life.
- It will feature an artificial moon, cloud seeding, robotic gladiators and flying taxis.

Are we genetically inclined for superstition or just fearful of the truth?
- From secret societies to faked moon landings, one thing that humanity seems to have an endless supply of is conspiracy theories. In this compilation, physicist Michio Kaku, science communicator Bill Nye, psychologist Sarah Rose Cavanagh, skeptic Michael Shermer, and actor and playwright John Cameron Mitchell consider the nature of truth and why some groups believe the things they do.
- "I think there's a gene for superstition, a gene for hearsay, a gene for magic, a gene for magical thinking," argues Kaku. The theoretical physicist says that science goes against "natural thinking," and that the superstition gene persists because, one out of ten times, it actually worked and saved us.
- Other theories shared include the idea of cognitive dissonance, the dangerous power of fear to inhibit critical thinking, and Hollywood's romanticization of conspiracies. Because conspiracy theories are so diverse and multifaceted, combating them has not been an easy task for science.
A growing body of research suggests COVID-19 can cause serious neurological problems.
- The new study seeks to track the health of 50,000 people who have tested positive for COVID-19.
- The study aims to explore whether the disease causes cognitive impairment and other conditions.
- Recent research suggests that COVID-19 can, directly or indirectly, cause brain dysfunction, strokes, nerve damage and other neurological problems.
