A new research indicates that Los Chocayos’ super -audition has had a big impact on Earth’s climate, but its duration of this impact was just a few decades – much shorter than thought.
A new one published in Communications Earth & Environment is revealing new data on one of the largest volcanic eruptions From the Quaternary Period – The Opereruction of Los Chocayos in Central America.
Previously, the eruption was thought that had triggered prolonged global cooling, but the new investigation used ice nuclei samples and suggests that the climate impact of the eruption was Significant but short -lived.
Scientists at the University of St Andrews analyzed samples of Granelândia and Antarctic ice nuclei, which preserve old climate records, including volcanic ash deposits and sulfate markers. By identifying the digital geochemical impression of the eruption of Los Chocayos in these samples, the researchers determined that the event took place about 79 500 years, says.
Overrerupts characterized by their great explosive power have the potential to inject large amounts of gases and particles into the upper atmosphere, significantly affecting global temperatures. However, although the eruption of Los Chocayos initially caused serious disturbances in climatic systems, the ice core data indicates that the Earth climate recovered in just a few decadesinstead of maintaining long -term cooling effects.
This discovery contradicts previous theories that suggested that the eruption could have contributed to The beginning of a glacier era. “Our evidence that the climate has returned to pre-service conditions in the years to decades that followed this catastrophic emission of volcanic sulfate is an exciting step towards our understanding of Vulcanism-Clima interactions,” explains the main author of the study, Helen Innes.
The team is now focusing on the analysis of other large volcanic sulfate deposits to further improve their understanding of how overrules influenced the evolution of the planet’s climate.
Although over -ruptions remain rare, they are a source of concern due to their potential Disturb the global climate and human societies. Fortunately, the University of St Andrews estimates that the probability of occurrence of such an event in the next century is only 0.12 percent.
