SYDNEY: Mass bleaching has killed more than a third of the coral in the northern and central parts of Australia’s Great Barrier Reef, though corals to the south have escaped with little damage, scientists said on Monday.
Researchers who conducted months of aerial and underwater surveys of the 2,300-kilometer (1,400-mile) reef off Australia’s east coast found that around 35 percent of the coral in the northern and central sections of the reef are dead or dying, said Terry Hughes, director of the ARC Center of Excellence for Coral Reef Studies at James Cook University in Queensland state.

El Paso flights resume after US anti-drone system prompts sudden shutdown
- Aviation officials lifts restrictions after sudden overnight halt
- FAA, US Army in dispute over laser anti-drone system
WASHINGTON: A secret military laser-based anti-drone system prompted the Trump administration to ban air traffic for more than seven hours in and out of the Texas border city of El Paso after US aviation officials raised drastic concerns about the safety of commercial air traffic.
The sudden closure of the nation’s 71st busiest airport by the Federal Aviation Administration stranded air travelers and disrupted medical evacuation flights overnight. The FAA initially said the closure would last 10 days for “special security reasons,” in what would have been an unprecedented action involving a single airport. Government and airline officials, speaking on condition of anonymity, said the FAA closed the airspace due to concerns that an Army laser-based counter-drone system could pose risks to air traffic. The two agencies had planned to discuss the issue at a February 20 meeting but the Army opted to proceed without FAA approval, sources said, which prompted the FAA to halt flights.
The Army’s laser was a direct-energy weapon called LOCUST and is manufactured by AeroVironment, a Virginia-based drone and counter-drone defense firm, two people briefed on the matter said. The company and the Pentagon did not immediately respond to requests for comment.
The FAA lifted its restrictions after the Army agreed to more safety tests before using the system, which is housed at Fort Bliss, next to El Paso International Airport.
The White House was surprised by the El Paso airspace closure, according to two sources speaking on condition of anonymity, touching off a scramble among law enforcement agencies to figure out what happened.
The FAA lifted the restrictions shortly after the situation was discussed in the office of White House chief of staff Susie Wiles, the sources said. US Transportation Secretary Sean Duffy, who oversees the FAA, said the closure had been prompted by a drone incursion by a Mexican drug cartel. However, a drone sighting near an airport would typically lead to a brief pause on traffic, not an extended closure, and the Pentagon says there are more than 1,000 such incidents each month along the US-Mexico border.
FAA Administrator Bryan Bedford met senators on Wednesday and told them there could have been better coordination about the move but did not answer detailed questions about why the agency initially planned a 10-day halt to flights, lawmakers said. Senate Commerce Committee chair Ted Cruz, a Texas Republican, and Senator Ben Ray Lujan, a New Mexico Democrat, both called for a classified briefing to get more answers. “The details of what exactly occurred over El Paso are unclear,” Cruz said.
The move had stranded numerous aircraft from Southwest Airlines, United Airlines and American Airlines at the airport, which handles about 4 million passengers annually.
El Paso Mayor Renard Johnson said the FAA did not reach out to the airport, the police chief or other local officials before shutting down the airspace.
“I want to be very, very clear that this should have never happened,” he said at a news conference.
The US official in charge of airport security, Transportation Security Administration Acting Administrator Ha Nguyen McNeill, also told Congress that she had not been notified.
“That’s a problem,” said Republican Representative Tony Gonzales of Texas, who said there are daily drone incursions along the US-Mexico border.
Airlines caught off guard
Airlines were also caught off-guard by the early Wednesday announcement. Southwest Airlines said the effects should be minimal for its 23 daily departures scheduled.
“FAA has not exactly acquitted itself credibly, objectively, or professionally,” said Bob Mann, an airline industry consultant. “The question should be, do we get an explanation?”
Trump has repeatedly threatened to deploy US military force against Mexican drug cartels, which have used drones to carry out surveillance and attacks on civilian and government infrastructure, according to US and Mexican security sources.
Mexican President Claudia Sheinbaum said at her daily news conference that her administration would try to find out what exactly happened but had no information about drone traffic along the border.
Tensions between the US and regional leaders have ramped up since the Trump administration mounted a large-scale military buildup in the southern Caribbean, attacked Venezuela and seized its president, Nicolas Maduro, in a military operation. The FAA curbed flights throughout the Caribbean after the attack, forcing the cancelation of hundreds of flights.
