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 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 40 people in the area of New Haven Green were believed to have overdosed on some form of K2 that may have been laced with opioids, 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.Director of Emergency Operations for New Haven Rick Fontana 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. Because of that, authorities believe there was some form of opioid or synthetic fentanyl 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." 2131

Newsom said in his Friday decision that she still poses a danger if released.Van Houten is serving a life sentence for helping Manson and others kill a Los Angeles couple in 1969. She was 19 years old at the time.Van Houten's attorney has said that she will appeal.This story was originally published by Tori Cooper on KERO in Bakersfield, California. 783

As we drive down the eerily deserted Hong Kong-Zhuhai-Macau Bridge, the murky waters of the Pearl River Delta stretch as far as the eye can see. There is no land in sight.Spanning 34 miles (55 kilometers), this is the longest sea-crossing bridge ever built. Guo Xinglin, assistant director and senior engineer at the Hong Kong-Zhuhai-Macao Bridge Authority, meets us half way along. As we are buffeted by a strong wind, the tough conditions his construction crew experienced, as they perched on precarious platforms, working miles from land and high over the water, are evident.Guo is visibly proud of his country's monumental achievement. 647
