John Moore/Getty Images(CNN) - Two sisters kayaking on the Arkansas River this summer made a historic find a huge bear skull that is hundreds if not thousands of years old. The skull is believed to have been preserved in the sands of the river until it was displaced by major flooding this year. Ashley and Erin Watt were kayaking down the river in south-central Kansas in August when they saw the skull protruding from a sandbar, the Kansas Department of Wildlife, Parks and Tourism said. When they pulled it out, they saw the skull had massive teeth, some the diameter of a human thumb. The sisters posted the find on Facebook, where it drew the attention of a wildlife department game warden.

Temperatures in Denver could plummet 50 degreesA drastic temperature drop Wednesday will make it feel like Denver has gone from fall to winter in 24 hours. Much of Colorado will transition from hazardous fire conditions to a freeze warning in only a matter of hours. This temperature plunge will start in the northern Rockies and dive southward to parts of northern Texas by Friday morning. The storm system intensifies and moves Wednesday night into the northern Plains, with winter storm warnings issued there and 1 to 2 feet of snow expected. In addition to falling limbs, these winds will also contribute to blowing snow conditions, diminishing visibility on roads.

John Moore/Getty Images(CNN) - A strong snowstorm is expected to hit the Denver region this week, ushering in a drastic temperature drop as it delivers the area's first snow of the season. Temperatures will plummet Wednesday from a high around 80 degrees Fahrenheit into the 20s at night as the storm pushes in, the National Weather Service's Denver office said. The heaviest snow is expected on Thursday, with 2 to 5 inches in the lower elevations and upwards of 10 inches in the higher elevations west of the city. Residents should watch out for icy roadways, as well as falling limbs due to strong winds. The storm system also will bring snow to the North-Central Rockies and Northern Plains, where winter storm advisories have been issued.

The episode, detailed in the new book titled "Border Wars," reveals the President's belief that people from Somalia posed a danger to the US. Months earlier, Trump targeted foreign nationals coming to the US from eight countries, including Somalia, in his "travel ban" executive order. CNN purchased a copy of "Border Wars," by The New York Times' Julie Hirschfeld Davis and Michael D. Shear, ahead of its official release. "Border Wars" dives into the back and forth between career officials and Miller, who's been an active proponent of lowering the number of refugees admitted to the US. Democrats and Republicans were at an impasse over immigration, especially the President's border wall.

John Moore/Getty ImagesLONDON - More than 250 million school-aged children and adolescents will be classed as obese by 2030, putting huge pressure on healthcare systems, a new report on childhood obesity warns. There are currently 158 million obese children around the world, according to the World Obesity Federation's first Atlas of Childhood Obesity, which calculated a risk score for obesity in the coming decade for 191 countries. Dr. Lobstein said he had been surprised by the "extraordinary increase" in the number of obese children forecast by the report. As childhood obesity is closely associated with obesity in adulthood, it would place a huge burden on health systems given the link with chronic diseases like diabetes, he warned. In absolute terms, the US is expected to have 17 million obese children by 2030, the largest number after China and India.

Joel Smithers, who was convicted of 859 counts of illegally prescribing drugs, faces between 20 years and life in prison, the US Department of Justice said in a news release.

A woman from West Virginia died after Smithers prescribed her oxycodone and oxymorphone, the Justice Department said. Every day, more than 130 people in the United States die from opioid overdoses, according to the National Institute on Drug Abuse.

John Moore/Getty ImagesTAIPEI, Taiwan - Taiwan's ruling party has warned citizens against traveling to Hong Kong or mainland China, saying the situation is "severe," after a Taiwanese businessman was detained following a visit to the protest-wracked city. Lee Meng-chu, 43, disappeared after he crossed over the border from Hong Kong to the mainland Chinese city of Shenzhen on August 19. Chen said Lee had attended a protest in Hong Kong before crossing the border. "The situation inside Hong Kong and China is severe and travel should be reduced. Cross-strait tensions have only worsened since the Hong Kong protests began in June, sparked by a now-withdrawn extradition bill between Hong Kong and mainland China.

Climate change is not affecting the world equally or at the same pace. Geoengineering has long been seen as something out of science fiction, or a dangerous distraction from more practical solutions to climate change. "(For these countries) there might be a risk of harm from doing this stuff, but you've got to balance this against the certain risks of unabated climate change," said Jeff McGee, a senior lecturer in climate change law at the University of Tasmania. "If you want to quickly reduce global temperatures, then the only known method currently is solar geoengineering," said Parker, the SRMGI expert. The country is both a major polluter and at major potential risk from climate change, and its leaders have invested heavily in geoengineering research alongside renewable energy and slowly moving away from China's dependency on coal.

John Moore/Getty ImagesWHATCOM COUNTY, Washington (CNN) - After an elderly couple in Washington state was found dead in an apparent murder-suicide, investigators said they found notes suggesting the pair was struggling to pay medical bills. Brian Jones called 911 on Wednesday morning and told the dispatcher he was going to shoot himself, according to the Whatcom County Sheriff's Office. Deputies arrived about 15 minutes later and a crisis negotiator tried to contact Jones for about an hour, the sheriff's office said, before deputies sent in a robot-mounted camera. Several notes left behind cited Whitney-Jones' "severe ongoing medical problems" and expressed concerns that the couple "did not have sufficient resources to pay for medical care," investigators said. One note also contained information about the couple's next of kin, the sheriff's office said.
