Explorer Matthieu Tordeur and glaciologist Heïdi Sevestre completed a challenging kite-ski journey across Antarctica last autumn, covering 4,000 kilometers over 80 days in extreme conditions, with temperatures dropping as low as -50 °C. Their expedition, called Under Antarctica, combined adventure with scientific research. During the trip, they used a geological radar to examine how snow accumulates on the polar ice cap and to locate hidden lakes and rivers beneath the ice. Their goal was to improve understanding of climate change and its impact on polar regions. Tordeur highlighted the role of such expeditions in raising public awareness about environmental issues. He noted that scientists often struggle to communicate their findings effectively to the general public, and adventurous projects like Under Antarctica can help bridge that gap. The journey gained significant attention on social media, and its educational materials were used by 300,000 schoolchildren around the world, providing them with insights into polar science and climate change. However, not all experts share the same enthusiasm for such ventures. Martin Ménégoz, a researcher at the Institute of Environmental Geosciences in Grenoble, expressed doubts about the scientific value of these expeditions. He argued that they contribute little to ongoing research and rarely produce data that significantly advances scientific understanding. Ménégoz also pointed out potential flaws in the scientific methods used, such as the timing of data collection and the rigor of the protocols, which may not align with the standards of long-term studies. Despite these concerns, Ménégoz acknowledged that the visibility brought by adventurers like Tordeur and Sevestre can help draw attention to climate issues. He noted that researchers may not always have the resources or opportunity to engage the public in the same way, and such expeditions can play a role in raising awareness, even if their scientific contributions are limited.
