Study Reveals Ice Wedges are Thawing at Rapid Pace Throughout the Arctic

Throughout the Arctic, ice wedges are thawing at a rapid pace. Changes to these structures, which are very common in permafrost landscapes, have a massive impact on the hydrology of the tundra. This is the result of a study carried out by an international research team in cooperation with the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI), which will be published in the journal Nature Geoscience today.

New Model to Improve Predictions of Permafrost Area and Stability in Northern High Latitudes

Uncertainties are a fact of life for those who model climate change and the factors that amplify or moderate its effects. One important dynamic in climate change studies is the extent of permafrost (permanently frozen soils) in the northern high latitudes and the rate at which it defrosts as the climate warms.

Surprising Finding Highlights Significance of Reducing Greenhouse Gas Emissions to Mitigate Arctic Climate Change

The drastic cut in sulfate particle emissions in Europe partly explains the amplified Arctic warming since the 1980s, shows a new study published in Nature Geoscience. The team, which consists of scientists from Stockholm University and the Norwegian Meteorological Institute, say that their surprising finding highlights an even more urgent need for reducing greenhouse gas emissions to mitigate Arctic climate change.

Study Results Confirm Ocean Played Significant Role in Rise of Atmospheric Carbon Dioxide

As the Earth emerged from its last ice age several thousand years ago, atmospheric carbon dioxide increased and further warmed the planet. Scientists have long speculated that the primary source of this CO2 was from the deep ocean around Antarctica, though it has been difficult to prove.

Upside-Down Rivers of Warm Ocean Water Threaten Stability of Floating Ice Shelves in Antarctica

“Upside-down rivers” of warm ocean water threaten the stability of floating ice shelves in Antarctica, according to a new study led by researchers at the University of Colorado Boulder’s National Snow and Ice Data Center. The study highlights how parts of Antarctica’s ice sheet may be weakening due to contact with warm ocean water.

Rising Temperatures Worldwide Change Weather Systems and Distribution of Water Around Globe

Rising temperatures worldwide are changing not only weather systems, but - just as importantly - the distribution of water around the globe, according to a study published today (March 14, 2016) in the journal, "Scientific Reports."

Carbon Stored in Arctic Soil’s Permafrost Layer Could Accelerate Global Warming

Neil Sturchio, professor and chair of the University of Delaware's Department of Geological Sciences, is exploring how the thawing of permafrost, a subsurface layer of soil that remains mostly frozen throughout the year, affects vegetation and the carbon cycle in the Toolik Lake area of the Alaska's North Slope.
