Predicting the expected loss of ice sheet mass is difficult due to the complexity of modeling ice sheet behavior. To better understand this loss, a team of researchers has been improving the reliability and efficiency of computational models that describe ice sheet behavior and dynamics.

As the Arctic continues to change due to rising temperatures, melting sea ice and human interest in developing oil and shipping routes, it's important to understand belugas' baseline behavior, argue the authors of a new article.

The catastrophic release of fresh water from a vast south American lake at the end of the last Ice Age was significant enough to change circulation in the Pacific Ocean according to new research. The study reveals that the lake, which was about one third the size of Wales, drained several times between 13,000 and 8,000 years ago, with devastating consequences.

New research confirms there really was a giant, flightless bird with a head the size of a horse's wandering about in the winter twilight of the high Arctic some 53 million years ago.

New measurements from a NASA satellite have allowed researchers to identify and quantify, for the first time, how climate-driven increases of liquid water storage on land have affected the rate of sea level rise. A new study shows that while ice sheets and glaciers continue to melt, changes in weather and climate over the past decade have caused Earth's continents to soak up and store an extra 3.2 trillion tons of water in soils, lakes and underground aquifers, temporarily slowing the rate of sea level rise by about 20 percent.

A new study on climate change and geochemical process of waters and lake sediments on the Tibetan Plateau show that global warming affects geochemical processes such as glacier melting, soil erosion and sediments release. This deteriorates water quality of rivers and lakes, thus significantly impacting the lives of 40 percent of the world’s population living in the area.

A bed of fossilized, methane dependent clams has for the first time been observed in the high Arctic. It tells the story of a thousand year long methane release event.

A future warming of the Southern Ocean caused by rising greenhouse gas concentrations in the atmosphere may severely disrupt the stability of the West Antarctic Ice Sheet. The result would be a rise in the global sea level by several meters.

Over the past 20 years, many ice shelves in Antarctica have shrunk and some have disappeared entirely. This has resulted in a significant acceleration of many Antarctic glaciers, contributing to rising sea levels. Researchers have used a complex model to show for the first time at what point the 'buttressing' role of ice shelves is impaired due to their decline.

Climate change projections that look ahead one or two centuries show a rapid rise in temperature and sea level, but say little about the longer picture. A new looks at the next 10,000 years, and finds that the catastrophic impact of another three centuries of carbon pollution will persist millennia after the carbon dioxide releases cease.

A dendroclimatologist and his fellow researchers were able for the first time to precisely reconstruct the summer temperatures in central Asia for the past 2,000 years. This was made possible by new tree-ring measurements from the Altai mountains in Russia. The results complement the climatological history of the European Alps, stretching back 2,500 years, that the research team has published in the past.
