A team of international researchers has shown for the first time how 18 meltwater lakes in Greenland collapse during winter which cause the edges of the ice to flow faster. The new knowledge is essential for understanding how climate change influences the flow of ice masses in the Arctic

Scientists report complete collapse of East Antarctica’s Conger Ice Shelf
Satellite data has confirmed that an ice shelf about the size of Manhattan has completely collapsed in East Antarctica within days of record high temperatures. The Conger ice shelf, which had an approximate surface area of 1,200 square km, collapsed around March 15, scientists confirmed today.
UCI researchers identify primary causes of Greenland’s rapid ice sheet surface melt
Irvine, Calif., May 5, 2021 — Intense, wide-spread melting events in Greenland, such as one in July 2012 that touched nearly every part of the massive island’s frozen slab, are catastrophic, but they still account for only a small portion of the total deterioration of the ice sheet, according to researchers at the University of California, Irvine.
Greenland landscape history preserved under 1.4 kilometers of ice
Greenland wasn’t always covered in ice. In fact, within the last 1.1 million years ,Greenland had thriving vegetation and ecosystems. That is the conclusion of an international group of researchers including a scientist from Lawrence Livermore National Laboratory (LLNL) that analyzed sediment at the base of the Camp Century ice core (1.4 kilometers deep) collected in 1966. The research appears in the Proceedings of the National Academy of Sciences.
Antarctic ice sheets could be at greater risk of melting than previously thought
Antarctica is the largest reservoir of ice on Earth – but new research by the University of South Australia suggests it could be at greater risk of melting than previously thought.
