Researchers from the University of Science and Technology Beijing and Hokkaido University tested Bi-2212 and Nb3Al superconducting materials under identical electron irradiation conditions to assess their suitability for future fusion magnets. ^[1] The 13‑year observing data presented in the Journal of Glaciology shows that the entire Qaanaaq glacier area lost an average of 5.4 meters of thickness during the 2012-2025 period. ^[2] Bi-2212 began showing visible changes after 25 minutes of irradiation, and its layered structure disappeared completely after 50 minutes as it became fully amorphous. ^[3] Nb3Al maintained its A15 crystal structure and long-range structural order for at least 90 minutes under the same irradiation conditions without showing signs of becoming amorphous. ^[4] The experiment exposed thin samples of both superconductors to 1,250-kiloelectronvolt electrons at room temperature with a flux of 2.92 × 10²³ electrons per square meter per second. ^[5] From July 2012 to 2025, a joint research team from Japan's Hokkaido University, Nagoya University, and the National Institute of Polar Research conducted field observations on the Qaanaaq glacier in northwestern Greenland, filling a gap where no long‑term data had been collected due to difficult access. ^[6] Shin Sugiyama, director of the Arctic Research Center at Hokkaido University, said the long‑term observation of the Qaanaaq glacier in the previously unaT Nusing area of northwest Greenland will aid predictions of sea‑level rise and ocean circulation changes, and contribute to disaster planning for local environmental change. ^[7] The researchers predict that if the Greenwich temperature rises by an additional 1°C, the rate of ice loss in the Qaana-q glacier will double relative to the present rate. ^[8]
