As the polar ice caps retreat, polar bears could struggle to survive by the end of this century, a number of university researchers wrote in a study published in the Nature Climate Change journal.The study looked at a number of sub-species of polar bears who live in the arctic and how they have adapted to reduced sea ice from 1979 to 2016. The group of researchers said that all but a few sub-species of polar bears will be able to reproduce and survive given projected conditions by 2100.Polar bears use sea ice to capture seals for food. When sea ice erodes for the summer, polar bears fast. Although polar bears are capable of fasting for months, there are limits to how long the bears can go without food.The researchers examined energy needs of polar bears, and that the amount of time polar bears would fast would lengthen to a point that makes it too challenging to survive and reproduce.While resting female polar bears can generally fast for longer periods of time, reproducing females, males and cubs all require shorter fasting periods, the research found.“Avoiding continued sea-ice decline requires aggressively mitigating greenhouse gas rise,” the researchers wrote, “and our results explicitly describe the costs to polar bears of avoiding that mitigation.”To illustrate how much sea ice is being lost, NOAA is projecting that the arctic could have ice-free summers by 2042.Scientists have long discussed the possibility that polar bears could become nearly extinct by the end of the century. Beyond reducing carbon emissions, proposals have included relocating cubs to areas of the Arctic expected to retain higher levels of sea ice have been proposed.

As the Miami Marlins and Philadelphia Phillies prepare to return to play following a week hiatus, the St. Louis Cardinals will be forced to sit out for another few days.On Monday, MLB announced it has postponed this week's three-game series between St. Louis and Detroit following a number of Cardinals players testing positive for the coronavirus late last week. The Cardinals' COVID-19 outbreak was the second COVID-19 rash MLB has encountered since resuming the season 11 days ago.According to MLB, 13 members of the Cardinals, including players and staff, have tested positive for the virus. The team has been holed up in Milwaukee since Thursday and remains quarantined there. The team is slated to resume play on Friday in St. Louis against the Cubs.The start of the coronavirus-shortened MLB season has been bumpy as several prominent players have opted to walk away from the season. Most notably, Mets star slugger Yoenis Cespedes said Sunday he would no longer participate in the 2020 season over coronavirus concerns.Earlier in the weekend, Red Sox ace Eduardo Rodriguez declined to return to baseball after facing complications from the coronavirus. Rodriguez told MassLive that he discovered a heart condition following his bout with the virus. 1264

At X3 Sports, trainers have a goal of bringing out the warrior within their students by building up their cardiovascular endurance and their self-confidence.After being shut down because of COVID-19 concerns, this mixed martial arts gym in Atlanta is reopening and seeing a major increase in enrollment.“Since a lot of things have been going on in our community, it has increased at least 50% than what it was,” kickboxing coach Rica Grandison said.Grandison says more people are taking these self-defense classes and citing concerns ranging from the pandemic to the protests.She added that these students enrolling represent all races, genders and sexual orientations:“I am part of the LGBTQ community,” Grandison said.“I’ve been called the 'N' word just waiting for a bus. I’ve been called the 'D' word just hanging out with my partner, my significant other at the time,” she said. “So, I have been there.”Now the X3 coaches are sharing their championship credentials with gym members like Shannon Dunlap, who joined this gym to get stronger physically and emotionally.“I am a lot more comfortable in my body; I’m a lot more self-assured,” she said. “I don’t get nervous walking down the street.”The coaches at X3 say the more someone trains, the more muscle memory they will develop. Which means if they ever become a victim of an act of violence, it’s easier to escape that situation without things getting even more physical.“If somebody’s charging you just, just give them a push kick," Grandison said. “Push them away, knock them down, run away.”While Grandison says the best fight is a fight that never happens, she also believes it best for people to have the physical skills to defend themselves. 1714

Authorities have started the arduous task of trying to retrieve a US missionary feared killed on a remote Indian island, careful not to trigger conflict with the islanders.John Allen Chau was last seen last week when he traveled to the forbidden North Sentinel Island in the Bay of Bengal to try to convert the island's residents to Christianity. The Sentinelese, as they are known, have a decades-long history of repelling outsiders, a fact that is near certain to make the journey to find Chau a treacherous one.Indian authorities along with the fishermen who reported seeing Chau's body last week, went near the island on Friday and Saturday in an effort to figure out how to recover the body."We have mapped the area with the help of these fishermen. We have not spotted the body yet but we roughly know the area where he is believed to be buried," said Dependra Pathak, a top police official in the Andaman and Nicobar Islands.Pathak said the group spotted several tribe members carrying bows and arrows and walking around the area where the fishermen said they saw Chau's body being dragged and buried."The mission was done from a distance to avoid any potential conflict with the tribespeople as it's a sensitive zone," he said. "We are discussing with anthropologists and psychologists about the nature of the Sentinelese."Pathak said there are a lot of things to consider before they enter the island, including the psychology of its residents."There are legal requirements as well which we need to keep in mind while carrying out the operation. We are also studying the 2006 case where two local fishermen were killed. The bodies were recovered then," he said. 1678

As New Haven, Connecticut, Fire Chief John Alston Jr. spoke to reporters about a spate of drug overdoses on Wednesday, he heard shouting coming from behind him."We're getting another call of a person," Alston said.He quickly helped coordinate the response, and then returned to the microphone.That scene came on the same day that as many as 71 people in the area of New Haven Green were believed to have overdosed on some form of K2, according to New Haven police spokesman Officer David Hartman.New Haven Green is a large park and recreation area in the city's downtown.The patients included people of various ages and demographics, Alston said."It's a nationwide problem. Let's address it that way," he said. "It's a nationwide problem that people are self-medicating for several different reasons, and every agency -- police, fire, medical hospitals -- all are strained at this time. This is a problem that's not going away."New Haven police said one person is in custody.Rick Fontana, director of Emergency Operations for New Haven, said the patients had symptoms of increased heart rates, decreased respiratory rates and a lot of vomiting. Some people were unconscious, others were semi-conscious.No one has died, but two individuals are considered to be in serious, life-threatening condition. Some individuals who were released from the hospital needed to be treated a second time for an additional apparent overdose, Fontana said.K2 is a synthetic cannabinoid related to marijuana that is frequently laced with other drugs, said Dr. Sandy Bogucki of the Yale School of Public Health.In two cases, Narcan was not effective in the field, but a high dose of Narcan at the hospital was effective in combating the overdose effects. Authorities confirm the substance was synthetic cannabis and that other drugs weren't involved in the substance.The response from emergency responders has been "tremendous," Fontana said.He said authorities have been treating and sometimes transporting six or seven people at one time and the actions of first responders have been "lifesaving.""We hope this is coming to an end, but it's too early to tell."The-CNN-Wire 2162
