Meteorites are disappearing into the Antarctic ice as a result of the climate crisis, putting them out of reach of scientists, according to a new study.
The icy plains of Antarctica are a magnet for meteorite hunters such as Maria Valdes, a research scientist at the Field Museum of Natural History and the University of Chicago. Some 1,000 space rocks are found in the region each year. Their dark hue is easy to spot in the white expanse.
Local parameters such as topography and wind directions that can redistribute meteorites from blue ice fields into local meteorite traps have to be considered as well,” Valdes said. In the new study, co-lead author Tollenaar and her team projected the loss of meteorites under different climate change scenarios by combining climate modeling with their work from the 2022 paper. The meteorites can sink into the ice even if temperatures are below zero degrees Celsius .

Rising temperatures threaten to bury Antarctic meteoritesA new study suggests that rising temperatures in Antarctica could cause pristine meteorites to sink further into the ice, potentially leading to their loss. Researchers argue that efforts to find these space rocks need to be intensified before they disappear for good.
