What's Happening?
A study led by University of Victoria geographer Sophie Norris has utilized machine learning to predict global glacier erosion rates with unprecedented precision. Published in Nature Geoscience, the research provides estimates for erosion rates of over 180,000 glaciers worldwide, revealing that 99% of glaciers erode between 0.02 and 2.68 millimeters annually. The study highlights the complex factors influencing erosion, including temperature, water presence, rock types, and geothermal heat. This comprehensive analysis offers valuable insights into glacier dynamics and their impact on landscape formation.
