Half of the coral populations in the Great Barrier Reef off Australia’s coast have been killed off because of warming ocean waters, a new study says.Between 25-30 percent of all marine species rely on coral reefs at some point in their life cycle. The Great Barrier Reef is the world’s largest coral reef, covering nearly 133,000 square miles.It has more than 411 species of hard corals documented, as well as 1,500 species of fish and other animals.Researchers looking at coral populations over 30 years starting in 1995 found there was decline in both shallow and deeper water, and across different species. They said two in particular, branching and table-shaped corals, were especially hard hit in 2016 and 2017 because of record-breaking temperatures.The study finds climate change to be a key driver in reef disturbances that disrupt recovery.“The potential for recovery of older fecund corals is uncertain given the increasing frequency and intensity of disturbance events. The systematic decline in smaller colonies across regions, habitats and taxa, suggests that a decline in recruitment has further eroded the recovery potential and resilience of coral populations,” the researchers note.They also say the coral that spawn the larvae that makes more coral have declined dramatically over large stretches of the reef.“Corals are tremendously resilient because of their capacity to produce millions of babies but they/we desperately need a break from disturbances,” Andreas Dietzel, a professor at the ARC Center and a co-author of the paper, said in an email to the Washington Post. 1600

GRAND JUNCTION, Colo. – Colorado Parks and Wildlife officers overnight killed the bear they suspect attacked a 5-year-old girl early Sunday morning near Grand Junction.CPW says they saw the bear they believe to have been involved in the attack walking up to a home about a half-mile away from where the girl was attacked in east Orchard Mesa. The bear was killed before it entered one of three traps that had been set.The agency said officers are “confident” the bear is the same one involved in the attack based on its behavior, but they will continue searching for other bears in the area.The bear’s carcass will be transported to the CPW Wildlife Health Laboratory in Fort Collins for a necropsy."The necropsy, along with DNA results will provide the confirmation, but we are confident we have the right bear," said Area Wildlife Manager Kirk Oldham. "However, we will leave all three traps in place for the time being out of an abundance of caution."The girl, 5-year-old Kimberly Cyr, had gone outside around 2:30 a.m. Sunday to investigate noises she thought were coming from her dog, her mother told CPW officials.But the mother heard her daughter screaming and went outside to see a “large black bear” dragging her daughter. The bear dropped the girl when her mother screamed.Cyr was taken to St. Mary’s Medical Center in Grand Junction, where she received around six-dozen stitches, her mother said. She was in fair condition as of Sunday afternoon.  1471

Friends of Jamal Khashoggi, the dissident Saudi journalist killed in disputed circumstances in his country's consulate in Istanbul, have demanded that authorities in Riyadh produce his remains.After nearly three weeks in which it denied anything untoward had happened on in its diplomatic premises in Turkey, Saudi Arabia admitted Khashoggi had died but claimed it was the accidental result of a brawl.Turkish officials privately believe he was dismembered, and Saudi authorities have failed to produce his body or say where they where they believe it to be. All they would admit was that officials engaged in a cover-up.Speaking to reporters outside Saudi Arabia's Istanbul consulate Saturday, Turan Kislakci, the head of the Turkish Arab Media Association and a friend of Khashoggi, called on Saudi Arabia to hand over the journalist's body. "Give us Jamal, so we can have a funeral for him. So that all people who care about him, world leaders, can come here to Istanbul for the funeral," said Kislakci. 1014

HANCOCK COUNTY, Ind. — One family in Indianapolis got a present a little early this holiday season.U.S. Navy Lt. Tawnee Hinton has been in Djibouti, Africa with the Combined Joint Task Force working on counterterrorism operations for the last 14 months.While she was deployed, her four children, Amelia, 5; Leyton, 9; Avarie, 13, and Christian, 21, were only able to talk their mother over FaceTime or texting.“Though the Navy has taken me away from my family on several occasions, and my husband was deployed numerous times before his retirement, this was a particularly lengthy deployment,” Hinton said.One event Hinton didn’t miss this year was her daughter Avarie’s choir concert. Unknown to her children, Hinton was able to come home early and surprise them. 796
