From pizzly bears to strange fish, here’s why hybrid animal sightings are on the rise [[https://kraken12web.com kraken сайт]]

The bear scientists shot in the Canadian arctic in 2016 was a biological mystery. It looked like a grizzly bear, complete with long claws and a prominent snout, but most of its fur was white.

A vital system of Atlantic Ocean currents that influences weather across the world could collapse as soon as the late 2030s, scientists have suggested in a new study — a planetary-scale disaster that would transform weather and climate.
  
Call it a pizzly or maybe a grolar bear. Either way, scientists determined the animal was the rare offspring of a polar bear that mated with a grizzly, and as the Arctic melts and polar bears increasingly move on land, sightings of these hybrids are on the rise.

Several studies in recent years have suggested the crucial system — the Atlantic Meridional Overturning Circulation, or AMOC — could be on course for collapse, weakened by warmer ocean temperatures and disrupted saltiness caused by human-induced climate change.
  
Pizzly bears aren’t being born en masse, said Charlotte Lindqvist, a biology professor at the University of Buffalo whose lab focuses on evolutionary genetics. The accounts of the bears are mostly anecdotal, and it’s unclear how widespread the phenomenon is.

But the new research, which is being peer-reviewed and hasn’t yet been published in a journal, uses a state-of-the-art model to estimate when it could collapse, suggesting a shutdown could happen between 2037 and 2064.
  
For instance, eight of the bear hybrids were found to be the children of a particular female polar bear with a seeming proclivity for male grizzlies.

This research suggests it’s more likely than not to collapse by 2050.
  
But as global temperature rises and Arctic ice melts, polar bears will have more chances to encounter – and mate with – other bear species.

“This is really worrying,” said René van Westen, a marine and atmospheric researcher at the University of Utrecht in the Netherlands and study co-author.
  
“This might just be the beginning,” Lindqvist told CNN. “The pressure is on, and we can clearly see in certain areas polar bears are spending more time on land as the sea ice is disappearing. Brown and black bears are encroaching on more Arctic habitat. And I think that’s just going to expand.”

“All the negative side effects of anthropogenic climate change, they will still continue to go on, like more heat waves, more droughts, more flooding,” he told CNN. “Then if you also have on top of that an AMOC collapse … the climate will become even more distorted.”

A vital system of Atlantic Ocean currents that influences weather across the world could collapse as soon as the late 2030s, scientists have suggested in a new study — a planetary-scale disaster that would transform weather and climate.

Several studies in recent years have suggested the crucial system — the Atlantic Meridional Overturning Circulation, or AMOC — could be on course for collapse, weakened by warmer ocean temperatures and disrupted saltiness caused by human-induced climate change.

But the new research, which is being peer-reviewed and hasn’t yet been published in a journal, uses a state-of-the-art model to estimate when it could collapse, suggesting a shutdown could happen between 2037 and 2064.

This research suggests it’s more likely than not to collapse by 2050.

“This is really worrying,” said René van Westen, a marine and atmospheric researcher at the University of Utrecht in the Netherlands and study co-author.

“All the negative side effects of anthropogenic climate change, they will still continue to go on, like more heat waves, more droughts, more flooding,” he told CNN. “Then if you also have on top of that an AMOC collapse … the climate will become even more distorted.”
