'It’s going so fast': The decline of New Zealand's glaciers – video

Scientists responsible for monitoring the health of New Zealand's glaciers have revealed a trend of declining snow and ice. The 2023 survey was the 46th undertaken in a collaboration between the National Institute of Water and Atmospheric Research (Niwa), Victoria University of Wellington, and the Department of Conservation. The longstanding project captures an aerial portrait of more than 50 Southern Alps glaciers at a similar time each year to track how they change. The team spent nearly eight hours travelling back and forth over the alps, taking thousands of aerial photographs of glaciers of differing sizes and orientations to use in various national and international research projects, including one that builds 3D models used to compare snow and ice year-to-year
