  "account": "Mont Blanc's snowy summit has risen nearly two meters since 2023, French surveyors revealed on Wednesday following a high-altitude expedition. The new altitude stands at 4,807.47 meters (15,773 feet), just 1.9 meters (6 feet) higher than the 2023 reading. However, records from the previous year indicate the summit lost approximately 1.3 meters (4 feet) during that period. These fluctuations primarily result from changes in the snow and ice cap atop the mountain, influenced by factors like snowfall, wind, and temperature.\n\nThe measurements were conducted on September 17 at dawn, with surveyors, guides, and scientists spending over two hours on the summit. They carried nearly 30 kilograms (66 pounds) of measurement equipment, along with a drone that captured more than 1,300 images to create a three-dimensional model of the snow cap. Ground-penetrating radar was also used to investigate the ice and rock beneath.\n\nThe Haute-Savoie surveyors' association, responsible for these measurements, has been conducting them since 2001, creating a comprehensive record for scientists studying changes at the summit. The latest figure is comparable to the altitude calculated by Joseph and Henri Vallot in the 1890s, who used surveying and triangulation methods. Research by glaciologists in Grenoble suggests that Mont Blanc's summit is so high and cold that its ice rarely melts, making climate change have a minimal impact on the ice thickness over the 20th century.",
