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.

At least 105 people are dead after an earthquake rocked the Indonesian island of Lombok over the weekend, state media reported Tuesday.Another 236 people have been injured in the quake, according to the government's disaster management spokesman Sutopo Purwo Nugroho, who told the Antara News Agency that the casualty numbers could rise as the search continued for survivors.More than 20,000 people have been displaced since the 6.9-magnitude quake struck Lombok, a popular tourist destination, on Sunday night.The epicenter of the earthquake was in northern Lombok, a more residential and less developed part of the island. Most of the tourist resorts are located on the southern side of the island.Most of those killed were struck by falling debris from collapsed buildings, according to Nugroho. Among the many buildings destroyed on Lombok were two homes which housed around 80 underprivileged children. 915

AUSTIN, Texas -- Valarie Allman has been throwing discus for 10 years.“When you throw a discus it takes about two seconds, and it’s a combination of power, of grace, of strength… I like to think of it as a dance still," Allman said.She started sophomore year of high school. But it’s her dance background that she credits for her quick progression in the sport.“I had a weird knack for it," Allman said. "I think all those years of learning choreography and spinning and doing pirouettes weirdly carried over to the discus, and it kind of just seemed like a good fit right from the start.”Multiple days every week, she trains hard in the gym guided by her coach Zebulon Sion.“I’m responsible for every facet of her training," Sion said. "So that includes the strength-training concepts, if we do any type of running, fitness oriented things, plyometrics, and then of course the actual throwing.”Their chemistry is undeniable.At only 25 years old, Allman is considered a pro athlete. Her rigorous training is fueled by her desire to be a part of the next Olympics.“When I graduated college, I think that was the motivation to keep training. I missed the team in 2016 by three feet and it was kind of in that moment that I realized that I really wanted to try again,” Allman said.Consistency, discipline, attention to detail. Allman’s focus didn’t falter until she found out the 2020 Olympics had to be postponed.“It was pretty heartbreaking," Allman said. "I mean, to feel like you’ve put in so much to be prepared for it and to be healthy and to do everything right to feel like you’d have a chance to make the team and then for it to be postponed I think it kind of just made me question everything.”“Her motivation to throw kind of was gone a bit for her for a while," Sion said. "And then we kind of got to a point after a month, month-and-a-half of training going well in terms of lifting and training -- our goal was to get fit, get strong and refine the technical model that she has to get to a point where we could be at our best if that opportunity would come.”That opportunity did come. On August 1st in Rathdrum, Idaho, Allman beat the Women's Discus American Record.“I threw 70 meters and 15 centimeters, and the previous record was 69 meters and 17 centimeters.”The three-foot difference that kept her from qualifying for the Olympics in 2016 is the difference she surpassed to become the first and only American woman to throw past 70 meters.“When you’re throwing that type of distance, three feet is significant. So to break it by almost three feet was huge actually,” Sion said.“When they measured the throw and they read out the numbers and it started with a seven I instantly burst into tears. I was absolutely shocked,” Allman said.Allman says 70 meters is the ultimate barrier. In the past 20 years, only two other women in the world have thrown past 70 meters.“Now looking back it’s wild the think it was just a sliver of a difference of giving up when we were on the brink of something incredible,” Allman said.“We could have called it we could have said 2020 is a bust ya know let’s move on," Sion said. "But the amount of time, energy, effort all the things to put in over five months of uncertainty and then for that to happen – I don’t know if I could be more proud.”The same day of her record-breaking throw was the exact day she would have been competing in Tokyo had the Olympics continued. However, with her dedication to improvement, Sion believes there’s a great future ahead of Allman.“I mean I think the goal is just to throw farther and to keep throwing far more often. I mean it’s pretty simple,” Allman said.Even more simple when you’re having fun. 3692
