Warming climate, volcanos raise risk of ice falls on Chile's glaciers
SANTIAGO (Reuters) -Chile's glaciers are facing a higher risk of collapse and landslides due to rising temperatures and the country's seismic and volcanic activity, according to an academic study. The study, published in the Journal of South American Earth Sciences in late May, modeled variables such as the possible sudden emptying of glacial lakes, mud and debris flows, avalanches, landslides, or abrupt glacial advances beyond normal speeds. "The study determined that around 10 glaciers ... would be highly susceptible" to one or more of those main destabilizing factors, said geologist Felipe Ugalde of the University of Chile, one of the study's authors. That included some glaciers at risk of ice avalanches, others that had steep overhangs, and some that could be affected by declining glacial lakes. Others faced risk from volcanic eruptions in the nation that sits on the Pacific "Ring of Fire," a belt of volcanos and earthquakes. "Three highly susceptible glaciers are those closest to the main emission centers of the San José volcano, highly susceptible to lahars," Ugalde said, referring to volcanic mud flows that are usually a mix of water, volcanic ash, and rock debris. The geologist added that glaciers globally were retreating amid warming temperatures, causing them to lose mass and become less stable over time. "When temperatures are high, water infiltrates either through rain or through rapid melting of the snowpack. This water percolates into the base of the glacier and acts as a lubricant," Ugalde said, adding this could cause ice to fall off more rapidly in a natural process called calving. "This is ultimately a response to the imbalance that glaciers are experiencing as a result of increasingly higher average air temperatures, even in high mountain environments," he said.

Officials issue warning after hikers spot huge invasive lizard lurking in state park: 'If you see it, back away safely'
Hikers were shocked to discover a giant invasive species of lizard — the Argentine tegu — in a California park. An article in Smithsonian magazine revealed that the Argentine tegu was spotted in Joseph D. Grant County Park, not far from San José. After the invasive species was discovered by hikers, park rangers began to search for the lizard and told members of the public to keep an eye out. Though the Argentine tegu does not pose a physical threat to humans, these lizards are not meant to be in the United States and can cause serious harm to local ecosystems. This tegu could be an escaped pet, according to the Smithsonian. "Please do not go searching for the tegu or trap it," Santa Clara County Parks stated on Facebook. "If you see it, back away safely and notify rangers as soon as possible." Tegus can grow up to 5 feet long, and they eat eggs and hatchlings of native species, such as ground-nesting birds, snakes, alligators, and tortoises. Often, invasive species are introduced to ecosystems by humans, and their presence has the potential to decimate native ecology. They are fast to reproduce and make survival difficult for the plants and animals that naturally are part of the habitat. By competing with native species for food and water, the whole balance of the area can be thrown into chaos and endangered species can be pushed closer to extinction. Protecting native species by prioritizing native plants, animals, and habitats can conserve natural resources and ensure food security, and it can also limit the spread of diseases among both animals and humans. In Florida, it's illegal to own tegus because of how invasive they are, and officials are in the process of trapping and euthanizing as many of these lizards as they can. "We can slow them down, but we can't stop them. They're here and they're reproducing," Kevin Donmoyer, an invasive species biologist at Everglades National Park, said, per Smithsonian. Though tegus are illegal to own and breed in many parts of the U.S., including Florida, they are legal to own in California. Perhaps if the invasive species problem gets worse, local governments will consider tightening the laws around owning these lizards. Should we be actively working to kill invasive species?

Marco Reus goal lifts Galaxy to tie with rival San José Earthquakes at Stanford Stadium
STANFORD — Marco Reus scored in the 70th minute and the Galaxy played the San José Earthquakes to a 1-1 draw on Saturday night in the 104th edition of the California Clásico. The Galaxy (1-14-5) are unbeaten in their past eight road matches (Stanford Stadium and PayPal Park) across all competitions against San José (7-8-5) dating to June 26, 2021. San José native Beau Leroux opened the scoring in the 16th minute with a shot into the upper-right corner for his fourth of the season. He settled Mark-Anthony Kaye's cross with his left foot and curled in a shot with his right from the top of the 18-yard box. San José goalkeeper Daniel stopped an initial attempt in the 70th, but it bounced right back to Reus for an easy touch home. It was Reus' first game wearing the captain's armband. Daniel made several key saves. He came out of his area to deny Joseph Paintsil on a one-on-one opportunity in the 60th. He also got a hand on Gabriel Pec's shot on a counterattack in the 88th. The Galaxy entered with just three of a possible 33 points on the road this season. San José announced the club sold 40,000 tickets for the game.
