Trees May Be Able to Warn Us When a Volcano Is About to Erupt
The science of predicting volcanic eruptions can genuinely save lives – potentially, a lot of lives – and researchers have shown that tree leaf colors can act as warning signals around a volcano that's about to blow. As volcanoes get more active and closer to an eruption, they push magma up closer to the surface, releasing higher levels of carbon dioxide. That in turn can boost the health of the surrounding trees, making leaves greener. And those changes – specifically in the measurement known as the normalized difference vegetation index (NDVI) – can be spotted by satellites in space. We could be looking at an early warning system for eruptions that doesn't require any local field work or ground sensors, so it could work in remote and difficult-to-access areas. "There are plenty of satellites we can use to do this kind of analysis," says volcanologist Nicole Guinn, from the University of Houston. Guinn was the first author of a recent study looking at carbon dioxide levels around Mount Etna in Italy. The study compared data from sensors around the volcano with satellite imagery, finding a strong relationship between more carbon dioxide and greener trees. Across the course of two years, the team found 16 clear spikes in carbon dioxide and the NDVI, matching magma movements underground. The patterns were even observed farther away from faults in the mountain. That study referenced earlier research from 2019, led by volcanologist Robert Bogue of McGill University, which showed that carbon dioxide emitted by two active volcanoes in Costa Rica had an impact on leaf color in tropical trees in the area. Now Guinn and Bogue, together with other researchers, are working on a project led by NASA and the Smithsonian Institution, analyzing changes in the color of plant life around volcanoes in Panama and Costa Rica. It's part of the collaborative Airborne Validation Unified Experiment: Land to Ocean (AVUELO) mission, which is looking to develop more ways in which we can measure the health of the planet from satellites. Current methods, like NASA's Orbiting Carbon Observatory 2, are only strong enough to pick up major eruptions. "A volcano emitting the modest amounts of carbon dioxide that might presage an eruption isn't going to show up in satellite imagery," says Bogue. "The whole idea is to find something that we could measure instead of carbon dioxide directly, to give us a proxy to detect changes in volcano emissions." There are multiple signals that can be interpreted to predict volcanic eruptions, including the rumble of seismic waves and changes in ground height. With the greening of leaves from carbon dioxide emissions, we now have another signal to measure – even if it won't be suitable for all sites. The AVUELO researchers are also interested in the broader effects of increased carbon dioxide on trees. As our world warms up due to human emissions of carbon dioxide, we could be increasingly reliant on vegetation to regulate this greenhouse gas. "We're interested not only in tree responses to volcanic carbon dioxide as an early warning of eruption, but also in how much the trees are able to take up, as a window into the future of the Earth when all of Earth's trees are exposed to high levels of carbon dioxide." says climate scientist Josh Fisher, from Chapman University in California and part of the AVUELO team.

Hundreds of animals could be euthanized because of massive overcrowding at DeKalb shelter
Animal advocates gathered Friday for the second annual State of DeKalb Animals address as the county works to relieve chronic overcrowding at its shelter. DeKalb County Commissioner Michelle Long Spears organized the address at the Emory Conference Center Hotel. It's an opportunity to bring local animal experts together to discuss challenges facing animal services and how to meet them. 'Our intake last year was the highest it's been since 2005, and this year it's trending higher,' said Rebecca Guinn, founder and CEO of the Lifeline Animal Project, which runs the county's shelter. [DOWNLOAD: Free WSB-TV News app for alerts as news breaks] Channel 2's Bryan Mims learned that in April, the DeKalb County Animal Shelter took in 757 animals, but its maximum capacity is 475. Through April, 212 animals have been euthanized at the shelter. 'Animals come into our care because of some human struggle or some human failure,' Guinn said. 'And I think people are struggling and there's always a collateral effect on their animals.' She says the state of the county's animals remains challenging. But she points to a so-called pet neighborhood under construction next the shelter that will house 120 animals, helping to ease overcrowding. It will have ten buildings with heating and air. TRENDING STORIES: DeKalb County pastor involved in $2.5 million legal battle over deal to sell church Missing father's kayak, paddle found in Lake Lanier cove Looking to buy a new home? Not in this neighborhood. The new trend hitting metro Atlanta This week, the DeKalb County Board of Commissioners passed an ordinance that targets uncontrollable breeding. It will limit a breeder to one litter per year and all breeders need a permit from the county. Andrea Siedl, a shelter volunteer, advocated for the new rules. 'Many of these backyard breeders are not vetting their animals,' she said. 'They're selling puppies younger than should be sold. They don't have vaccinations.' Guinn said the mission is to slow the tide of animals coming to the shelter and to save more animals' lives. 'Unfortunately, with these kinds of numbers we are looking at, because of the sheer lack of space, we have to make some tough decisions,' she said. [SIGN UP: WSB-TV Daily Headlines Newsletter]

Carlos Narváez, the Red Sox' backup plan at catcher, has been working out fine since an injury to starter Connor Wong
But Red Sox chief baseball officer Craig Breslow and Yankees general manager Brian Cashman found common ground after the 2023 season when oft-tardy outfielder Then they did it again a year later when the Yankees sent 26-year-old catcher Carlos Narváez to the Sox for a minor league pitcher. Advertisement Verdugo helped the Yankees get to the World Series last season. Now there's a chance Narváez could do the same for the Red Sox. Get Starting Point A guide through the most important stories of the morning, delivered Monday through Friday. Enter Email Sign Up Narváez has started 15 of the last 19 games since Connor Wong went on the injured list April 8 with a broken finger. The Sox are 10-5 in those games, and that's not a coincidence. Narváez has drawn praise from the pitchers for his receiving skills, and through Sunday he led major league catchers with six defensive runs saved. 'He can really catch,' said Sox righthander Walker Buehler, who has had Narváez behind the plate for all six of his starts this season. 'I've liked working with him.' The Sox moved on from backup catcher Reese McGuire last season with the July trade for Danny Jansen. Jansen signed with the Rays as a free agent in December, a few weeks before the Sox included top catching prospect Kyle Teel in the trade for Garrett Crochet. Advertisement They needed to bolster the position and targeted Narváez, knowing the Yankees had good catching depth. The Sox sent righthander Elmer Rodriguez-Cruz, a former fourth-round pick, to the Yankees for Narváez. A few weeks before they traded for Narváez, the Red Sox hired Parker Guinn away from the Yankees to join the major league coaching staff as a catching instructor. Guinn managed a Dominican Summer League team for the Yankees in 2024, then spent the final week of the season with Triple A Scranton/Wilkes-Barre. He got to know Narváez there as they talked during games and discussed catching techniques. 'When we traded for him, I immediately sent him some text messages making that connection,' Guinn said. 'It definitely helped knowing him a little.' In spring training, Guinn worked with Narváez on improving his throwing. Since the season started, many of their discussions have centered on leadership and the catcher's role of guiding the pitchers through a game. 'You have to speak up and be there for the pitcher,' Narváez said. 'I had to get to know the pitchers here. That's been a big improvement for me.' The physical aspects of catching — framing pitches and blocking balls in the dirt — are where Narváez excels. But there is much more to catching. 'The tools are clearly there,' Guinn said. 'But really taking the lead with Connor being out and really building relationships with those pitchers and learning how to navigate a game has been really impressive to see.' Advertisement Sox coaches also have taken note of how Narváez has jumped into game-planning, sitting at his locker and studying information before games. 'He does his homework,' manager Alex Cora said. When the Sox acquired Narváez, Cora got in touch with his winter league coach in Venezuela, former major league catcher Henry Blanco. Blanco provided a positive scouting report, saying Narváez was ready. That proved to be correct when he was needed to carry a heavier load than expected. Wong, who played his first rehab game for Triple A Worcester on Sunday, is expected back in the coming days. But Narváez is not going to be an occasional backup given what he has shown the team over the last three weeks. 'Sure, he will play a lot,' Cora said. Narváez has hit only .173 with a .511 OPS since replacing Wong but is 7 for his last 26 with two home runs. 'I think offensively there's more. We've just got to be patient,' Cora said. For a rookie still getting used to a new organization, Narváez is feeling at home. He was one of the Sox players gathered for a steak dinner in Toronto on Sunday night after 'This is my team now,' Narváez said. 'The guys have been great. It's good to be here.'
