MANOA, Hawaii – As much as 40% of all beaches on Oahu, Hawaii’s most populated island, could be lost by 2050 due to rising sea levels and the current policies to address the threat.That’s according to a new study from the University of Hawaii’s School of Ocean and Earth Science Technology.Researchers looked at the risk of shoreline hardening, the construction of seawalls and revetments. They say the process accelerates erosion and interrupts natural beach migration.Scientists assessed the Oahu shoreline that would be most vulnerable to erosion and identified the location and severity of risk of shoreline hardening and beach loss, and a potential timeline for the increase in erosion hazards.They found the most threatened properties fall into an “administrative erosion hazard zone,” an area likely to experience erosion hazards and qualify for the emergency permitting process to harden the shoreline.“By assessing computer models of the beach migration caused by 9.8 inches of sea level rise, an amount with a high probability of occurring before mid-century, we found that emergency permit applications for shoreline hardening to protect beachfront property will substantially increase,” said Kammie Tavares, who led the study.Co-author Dr. Tiffany Anderson says they’ve determined that almost 30% of all present-day sandy shoreline on Oahu is already hardened and another 3.5% was found to be so threatened that those areas qualify for an emergency permit now.“Our modeling indicates that, as sea level rises about 10 inches by mid-century, an additional nearly 8% of sandy shoreline will be at risk of hardening—meaning at that point, nearly 40% of Oahu’s sandy beaches could be lost in favor of hardened shorelines,” said Anderson.Fletcher and her fellow researchers are calling on government agencies to develop creative and socially equitable programs to rescue beachfront owners and free the sandy ecosystem, so that it can migrate towards land as it must in an era of rising seas.“It is urgent that options are developed soon for beachfront landowners and resource managers to avoid further destructive management decisions,” said Fletcher.“This research shows that conversations on the future of our beaches and how we will care for them must happen now rather than later, if we are to protect our sandy beaches,” said Tavares. 2354

Michigan Gov. Rick Snyder activated the state's Emergency Operations Center to monitor the reentry of China's Tiangong-1 space station, which is expected to reenter the Earth's atmosphere between March 29 and April 2.While most of the space station is expected to burn up during reentry, there is concern that debris could make landfall. According to the Aerospace Corporation, the 8.5 ton space station could land along a strip of the United States from northern California to Pennsylvania, which includes the southern lower peninsula of Michigan. “While the chances are slim that any of the debris will land in Michigan, we are monitoring the situation and are prepared to respond quickly if it does,” said Capt. Chris A. Kelenske, Deputy State Director of Emergency Management and Homeland Security and commander of the Michigan State Police, Emergency Management and Homeland Security Division (MSP/EMSHD). “The state will rely on its existing satellite reentry response and recovery plan for any necessary response protocols.”Debris could contain hydrazine, which is a highly toxic and corrosive substance. Any suspected space debris should be considered hazardous.Anyone who suspects they've encountered debris from the space station should report it by calling 911 and stay at least 150 feet away from it. 1330

Michelle Obama's nationwide tour for her new book "Becoming" has already helped the book achieve a publishing milestone.Barnes & Noble said Monday that Obama had "the biggest first-week sales of any book this year."Until November, that title belonged to Bob Woodward's Trump administration dissection, "Fear," which came out in September. But "Becoming" had even stronger sales in its first week, the bookseller said.Beyond just this year, B&N said "Becoming" had "the best first-week sales of an adult book since 'Go Set a Watchman' published in July, 2015."It has been nearly two years since the Obamas left the White House, but there is still intense interest in the former president and first lady."Becoming" remains No. 1 on the online lists kept by both the Amazon and Barnes & Noble websites.Her book landed in Amazon's No. 1 spot on Friday, November 9, and has not budged since.A gauntlet of TV interviews, including all three network morning shows, surely helped sales.The interviews will continue later this month. On Friday, November 30, she will be on "The Late Show with Stephen Colbert.""Becoming" came out on November 13. It is almost certain to rank No. 1 on the New York Times best selling books list, but that list won't officially come out until Wednesday.All the interest in the title — plus her nationwide arena tour — has stoked new speculation about her political prospects. Is there any chance she'd run for political office?"Let me be very clear, it will never happen," Obama adviser Valerie Jarrett told Alisyn Camerota on "New Day" Monday morning.As for Obama's husband, he is working on finishing his own memoir. Both books were acquired by Penguin Random House in a bidding war back in early 2017."Writing's hard," Barack Obama said at his foundation's annual summit on Monday. "I'm just sitting there, I type two words... delete."His remarks about the difficulties of writing were reported by The Atlantic. He reportedly told people to go buy his wife's book. 2009
