Iceberg ruptures in Patagonia raise alarm about global warming
Fabian Andres Cambero
Two new icebergs have broken off from the Grey Glacier in Chile’s Patagonia in recent weeks. Scientists have linked the increased frequency ice breaks to rising temperature. According to Ricardo Jana, researcher and member of the climate change area of the Chilean Antartic Institute (INACH) “In recent years temperature rises above the normal average and intense rainfall were registered with an increase in water level in the lake, factors that could explain the separation. Reseachers from universities in Germany and Brazil, together with experts from INACH and other local entities, have been studing the Grey Glacier since 2015.
