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.

AURORA, Colo. – Hundreds of people are expected to gather Friday evening to demand that three officers involved in the in-custody death of Elijah McClain be fired by the Aurora Police Department.“For ten months Aurora Police Department has shielded Elijah McClain's murderers on their force from facing any form of justice. It was only last Friday, just ahead of a mass march for Elijah, that they pulled the three killers off the streets and put them on paid desk duty,” the Party for Socialism and Liberation – Denver (PSL) said in a statement about the event. “We need to make it clear that this is absolutely NOT enough.”Last Friday, APD announced officers Nathan Woodyard, Jason Rosenblatt and Randy Roedema had been taken off street duty "because of threats and harassment," according to a police spokesperson. Police said those threats involved phone calls as well as email messages.Officials did not disclose to which department the officers were reassigned, but said they were working in a "non-enforcement capacity."The PSL says they expect murder charges “for the three killers” and demand that APD fire all three “IMMEDIATELY.”Organizers of Friday’s protest are also calling for the release of the names — as well as the immediate termination — of all officers involved in an incident involving a photograph taken near the site where McClain struggled with officers. The officers were seen in the picture imitating the carotid hold used on McClain before the 23-year-old Black man died last August.RELATED: Officer who was depicted in photograph at site of Elijah McClain's arrest has resignedThe rally will start at 6 p.m. at the intersection of Billings St. and Evergreen Avenue, the site where organizers say, “Elijah was brutalized and killed and where APD danced on his grave.” From there, protesters will march to the APD headquarters at the Aurora Municipal Center.The march and protest will put APD’s response to test once again, following a violent night of confrontation between officers and protesters last Saturday.MORE: Aurora Police Interim Chief defends police response to Elijah McClain protestOrganizers say there will be people of all ages at Friday’s protest, “who do not want a repeat of last Saturday’s violence from APD, but (who) will not be intimidated out of exercising their First Amendment right to assemble and voice their concerns.”McClain’s death, largely unnoticed for the past 10 months, recently garnered national media attention following nationwide calls to reform interactions between police and Black Americans in the wake of George Floyd’s death.On Tuesday, the Colorado U.S. Attorney's Office, along with several other law enforcement agencies, announced they've been reviewing facts in the death of the 23-year-old Black man since last year for a potential federal civil rights investigation, saying they were aware of the photo allegations which surfaced Monday evening and were gathering further information about the incident.This story was originally published by óscar Contreras on KMGH in Denver. 3062

Attention homeowners: if you haven't refinanced in the past year, you may want to think about it.Mortgage rates have dipped to a new low for the 11th time this year.This time, they're at the lowest point they've been since Freddie Mac started tracking rates almost 50 years ago.The national average for a fixed 30-year mortgage is 2.8%, and 2.33% for a 15-year mortgage.That's great news for people who are already in homes and want to stay there, but it won't help most buyers.Home prices are up an average of 15% over last year, as the inventory of available homes continues to fall. 593

ATLANTA (AP) — Atlanta police have accused a suspect of felony murder and aggravated assault in a shooting that killed an 8-year-old girl near the site of an earlier police shooting.Police said Wednesday that they issued warrants a day earlier for 19-year-old Julian Conley in the slaying of Secoriea Turner. Conley's attorney, Jackie Patterson, said Conley turned himself in Wednesday. Patterson says Conley was peacefully protesting and witnessed the shooting but did not open fire himself. Secoriea was fatally shot on the Fourth of July while riding in an SUV with her mother and another adult near the Wendy's restaurant where Rayshard Brooks, a 27-year-old Black man, was killed by a white police officer on June 12. 730

At first, your loved one with Alzheimer's may not react well to wearing a mask or having to wash their hands consistently, but the Alzheimer's Foundation of America says there are things you can do to ensure they are safe during this time."You have to do your best to try, but you also have to be forgiving of yourself and understand that there are limits to what you can do. Some of the nice things about these masks are some of them can be lovely and fun. You can pick masks that have themes or that have resonance with that person," Dr. Allison B. Reiss with The Alzheimer's Foundation of America, told KIVI-TV.For those who don't like the consistent handwashing, Dr. Reiss says buying soaps with a fragrance can make a big difference and encourage them to wash their hands more often."I think a lot of us have that, that olfactory memory, so a scent that you enjoy brings such good feelings. Like cinnamon apple smells of apple pie and childhood, vanilla. You know many people love the scent of a warm home kitchen or the scent of outdoors and flowers and gardens and grass. So that very much goes into an emotional center and people like that," Dr. Reiss said.Throughout all of this, one thing to remember is to talk to your loved one who has Alzheimer's in a soothing tone."So we want to try and be that calm safety for them, a safe environment, a secure feeling, a feeling of routine and that everything is just as it should be so that there's not that agitation and panic," Dr. Reiss said.To get more information and tips on how to keep your loved ones safe during the pandemic, you can visit the Alzheimer's Foundation of America's website.This story was originally reported by Stephanie Garibay on kivitv.com. 1728
