New research reveals how the speed of ocean currents and the shape of the seabed influence the amount of heat flowing underneath Antarctic ice shelves, contributing to melting.
Scientists at the University of East Anglia (UEA) used an autonomous underwater vehicle to survey beneath the Dotson Ice Shelf in the Amundsen Sea, an area of rapid glacial ice loss largely due to increasing ocean heat around and below ice shelves.
Five LMU researchers have been awarded Consolidator Grants by the European Research Council. Their projects deal with climate change, strokes, quantum physics, mitochondria, and cancer diagnosis.
A new study reveals significant temperature variations beneath Greenland, reshaping our understanding of its tectonic history.
These underground heat patterns influence how the ice sheet interacts with the bedrock, which is important for predicting future sea level rise in the context of climate change.
Climate change—including high temperatures and heat waves—has been shown to pose serious risks to the environment, food systems, and human health, but new research finds that it may also lead to delays in early childhood development.
