Researchers Identify Hundred of Methane 'Hotspots' Across Los Angeles Basin

Hundreds of methane-emitting hot spots have been identified across the Los Angeles Basin, including a “clean ports” truck refueling facility near the Port of Long Beach, power plants, water treatment facilities, and cattle in Chino, according to new findings by the University of California, Irvine.

Atmospheric scientists conducted a mobile survey across Los Angeles, Orange and Riverside counties, and their results, published this week in the Journal of Geophysical Research: Atmospheres, identify the region’s highest emitters. Methane is the second-largest known contributor to global climate change, behind carbon dioxide.

The survey was done before the Aliso Canyon gas well leak temporarily displaced thousands from their Porter Ranch homes. The findings could be used by the Southern California Gas Co. to meet orders by Gov. Jerry Brown and the state Air Resources Board to offset the gas leak by removing as much of the fast-acting greenhouse gas from the air as was emitted from the Aliso Canyon site, the researchers said.

Lead author Francesca Hopkins said the survey “identified numerous methane hot spots that could be targets for these mitigation activities.”

The researchers drove a specially equipped cargo van for hundreds of miles throughout the Los Angeles region, taking readings with instruments designed to measure methane, ethane, carbon monoxide and carbon dioxide. They observed heightened methane levels across the basin and pinpointed 213 hot spots.

“Our surveys demonstrate the prevalence of unwanted methane emissions across the Los Angeles urban landscape and show that two-thirds of the gas comes from fossil fuel origins,” said Hopkins, who began the work as a postdoctoral scholar at UCI. “Known sources of methane include cattle, geologic seeps, landfills and compressed natural gas fueling stations.”

Now an environmental scientist at the Jet Propulsion Laboratory in Pasadena, she said that while the recent leak in Aliso Canyon drew a lot of media and public attention, the leaks her team detected during the survey contribute to an ever-present dome of methane that hovers over the region.

A key factor in the scientists’ ability to create such a detailed map of emissions was their decision to collect surface samples from a roving vehicle. Equipped with a modified electrical system, a GPS, a rooftop sampling mast and spectrometers, the cargo van enabled them to continuously sample and analyze air wherever they went.

“Mobile measurements are really important because you can examine the fine-scale structure of variations in methane within neighborhoods and begin to identify the origins,” said Jim Randerson, UCI Chancellor’s Professor of Earth system science and principal investigator on the study. “It’s often not possible to pinpoint individual sources with aircraft observations.”

He added: “This work shows that small natural gas leaks are ubiquitous throughout the Los Angeles Basin. A critical next step is to develop a regional partnership with stakeholders to identify the source of these leaks and make a plan for fixing them.”

“I’m often asked about the prevalence of major methane point sources in cities,” said Riley Duren of JPL’s Megacities Carbon Project. “The answer is [that] we really don’t know at the moment, except in a handful of places where direct measurements are being made. Studies like this are helping us gain a much clearer understanding of the problem.”

Three Disney World Employees Among 17 Arrested in Florida Child Sex Sting

Three Disney World employees were among the 17 people arrested in a child sex sting operation in Florida, law enforcement officials announced on Wednesday.

In the operation, dubbed “Operation Child Protector,” undercover officers posed as 13- and 14-year-old children on social media and online dating apps between July 27 and Aug. 1.

The undercovers made contact with each of the suspects before proposing they meet at a location in Polk County, where they were busted.

In total, the arrests led to 49 felony and two misdemeanor charges. Those arrested were aged 26 to 47. All were from Central Florida except for one 33-year-old man from California.

“What you see on this board … are deviants. Incredible deviants,” Polk County Sheriff Grady Judd said at a press conference on Tuesday, motioning to photos of the alleged pervs. “They travel from as far away as Clewiston, Florida. One even came from Los Angeles.”

“Much to their chagrin, instead of meeting with young children, they were met by law enforcement officers who were online undercover posing as children.”

Kenneth Javier Aquino, 26, a lifeguard at Animal Kingdom Lodge at Disney World, was arrested while still wearing his Disney polo shirt and swimsuit, according to the sheriff’s office.

Aquino engaged in an online conversation on social media with an officer, posing as a 13-year-old girl, authorities said. He then asked the “girl” to send photos, and sent her an explicit video of himself, police said.

Aquino told officers he is a Navy veteran and has a pregnant girlfriend.

Jonathan McGrew, a 34-year-old custodian at Disney World, was nabbed by an undercover officer posing as a 13-year-old girl.

McGrew allegedly told the “girl” that he wanted her to come over and have sex with him and his girlfriend, 29-year-old Savannah Lawrence, who also works as a custodian at tourist mecca.

McGrew sent her explicit videos of him and Lawrence performing sexual acts on each other, authorities said.

A rep for Disney World didn’t immediately return a message.

China Reports First Human Death from Monkey B Virus

China has reported the first human infection and death in the country caused by a rare infectious disease found in primates known as the Monkey B virus.

The Chinese Center for Disease Control and Prevention said a 53-year-old veterinary surgeon who worked in a research institute specializing in nonhuman primate breeding in Beijing dissected two monkeys in March and became ill about a month later.

He began experiencing nausea, vomiting, fever and neurological issues, and died in May.

Blood and saliva samples were tested and researchers in April found evidence of the Monkey B virus, also known as the herpes B virus.

Researchers said a male doctor and female nurse who were in close contact with the victim tested negative for the virus.

The Monkey B virus is prevalent among macaque monkeys but infection among humans is extremely rare. Since the virus was identified in 1932, just 50 cases have been reported, with the majority of those in North America. Untreated B virus infections in humans are serious, however, with a fatality rate of about 80 percent.

Symptoms include fever, shortness of breath, and progress to more serious complications such as swelling of the brain and spinal cord.

Laboratory workers and veterinarians in close contact with the animals are most at risk as people typically get infected with the virus if they are bitten or scratched by an infected macaque, or have contact with the monkey’s eyes, nose or mouth.

But the virus is unlikely to mutate in a way that poses a problem to the general population. Just one case of human-to-human transmission of the virus has ever been documented.

U.S. Remembers 9/11 Terrorist Attacks as The Pandemic Changes Tribute Traditions

U.S. Remembers 9/11 Terrorist Attacks as The Pandemic Changes Tribute Traditions

Americans are commemorating 9/11 with tributes that have been altered by coronavirus precautions and woven into the presidential campaign, drawing both President Donald Trump and Democratic challenger Joe Biden to pay respects at the same memorial without crossing paths.

In New York, a dispute over coronavirus-safety precautions is leading to split-screen remembrances Friday, one at the Sept. 11 memorial plaza at the World Trade Center and another on a nearby corner. The Pentagon’s observance will be so restricted that not even victims’ families can attend, though small groups can visit the memorial there later in the day.

Trump and Biden are both headed — at different times — to the Flight 93 National Memorial near Shanksville, Pennsylvania.

Trump is speaking at the morning ceremony, the White House said. Biden plans to pay respects there in the afternoon after attending the observance at the 9/11 memorial in New York.

Meanwhile, Vice President Mike Pence is also due at ground zero — and then at the alternate ceremony a few blocks away.

In short, the anniversary of 9/11 is a complicated occasion in a maelstrom of a year, as the U.S. grapples with a health crisis, searches its soul over racial injustice and prepares to choose a leader to chart a path forward.

Still, 9/11 families say it’s important for the nation to pause and remember the hijacked-plane attacks that killed nearly 3,000 people at the trade center, at the Pentagon and near Shanksville on Sept. 11, 2001, shaping American policy, perceptions of safety and daily life in places from airports to office buildings.

“I know that the heart of America beats on 9/11 and, of course, thinks about that tragic day. I don’t think that people forget,” says Anthoula Katsimatides, who lost her brother John and is now on the board of the National Sept. 11 Memorial & Museum.

Friday will mark Trump’s second time observing the 9/11 anniversary at the Flight 93 memorial, where he made remarks in 2018. Biden spoke at the memorial’s dedication in 2011, when he was vice president.

The ground zero ceremony in New York has a longstanding custom of not allowing politicians to speak, though they can attend. Biden did so as vice president in 2010, and Trump as a candidate in 2016.

Though the candidates will be focused on the commemorations, the political significance of their focus on Shanksville is hard to ignore: Pennsylvania is a must-win state for both. Trump won it by less than a percentage point in 2016.

Around the country, some communities have canceled 9/11 commemorations because of the pandemic, while others are going ahead, sometimes with modifications.

The New York memorial is changing one of its ceremony’s central traditions: having relatives read the names of the dead, often adding poignant tributes.

Thousands of family members are still invited. But they’ll hear a recording of the names from speakers spread around the vast plaza, a plan that memorial leaders felt would avoid close contact at a stage but still allow families to remember their loved ones at the place where they died.

But some victims’ relatives felt the change robbed the observance of its emotional impact. A different 9/11-related group, the Stephen Siller Tunnel to Towers Foundation, set up its own, simultaneous ceremony a few blocks away, saying there’s no reason that people can’t recite names while keeping a safe distance.

The two organizations also tussled over the Tribute in Light, a pair of powerful beams that shine into the night sky near the trade center and evoke its fallen twin towers. The 9/11 memorial initially canceled the display, citing virus-safety concerns for the installation crew. After the Tunnel to Towers Foundation vowed to put up the lights instead, the memorial changed course with help from its chairman, former Mayor Mike Bloomberg, and Gov. Andrew Cuomo.

Tunnel to Towers, meanwhile, arranged to display single beams for the first time at the Shanksville memorial and the Pentagon.

Over the years, the anniversary also has become a day for volunteering. Because of the pandemic, the 9/11 National Day of Service and Remembrance organization is encouraging people this year to make donations or take other actions that can be accomplished at home.
