Towering ice pillars constantly crack as the ice moves forward, a movement barely noticeable daily but clear over time. While most glaciers retreat rapidly with rising temperatures, a limited group behaves differently, suddenly advancing for several months or years after a period of stagnation. This phenomenon is known as glacier advance. Standing before a slowly advancing glacier is an exceptional experience. In 2012, researchers from the University of Portsmouth witnessed this during fieldwork at Nathorstbreen glacier in the Svalbard archipelago in the Arctic, where the glacier advanced more than ten meters per day.
