A Leap Forward in Glacier Modeling. Loop is the open research network that increases the discoverability and impact of researchers and their work. download the GitHub extension for Visual Studio. The key to the sweeping new modeling method is its grounding in hard data. Glaciers are sensitive climate indicators that primarily respond to interannual changes in temperature and precipitation (e.g., Bertrand et al., 2012; Harrison, 2013). The observations cover nearly every glacier in High Mountain Asia, which covers an area of 38,000 square miles (98,000 square kilometers), including those too small to be captured in previous studies. This study seeks to quantify how accounting for debris cover, glacier dynamics, and feedbacks between the two will alter projections of glacier mass change for various RCP scenarios using the open-source Python Glacier Evolution Model (PyGEM). A new study tracing the sources of carbon dioxide, the most significant human-generated greenhouse gas, reveals the unexpectedly large influence of vegetation in urban environments. Global-scale 21st-century glacier mass change projections from six published global glacier models are systematically compared as part of the Glacier Model Intercomparison Project. In total 214 projections of annual glacier mass and area forced by 25 General Circulation Models (GCMs) and four Representative Concentration Pathways (RCP) emission scenarios and aggregated into 19 glacier … Susan Callery Each glacier is modeled independently using a monthly timestep. Learn more. Despite the model’s wide scope and high precision, its forecasting power is subject to the same limitation as previous projections: researchers don’t know whether emissions of heat-trapping greenhouse gases will increase, decrease, or stay the same in the decades to come.

NASA's Jet Propulsion Laboratory. To account for this, the team used the standard practice of delivering a range of forecasts under scenarios, for higher, lower, and largely unchanged emissions. 10. The region, known as High Mountain Asia, could see ice loss run from 29 to 67 percent, depending on the level of greenhouse gas emissions over the period modeled.

The ice in one of the world’s highest concentrations of non-polar glaciers could see significant melting before the end of the century, potentially affecting sea levels around the globe, according to a new computer model from the NASA Sea Level Science Team. they're used to log you in. According to the study, water flow in monsoon-fed river basins, driven largely by melting glaciers, could hit its peak by 2050 – potentially reducing runoff beyond that time and forcing changes in how water is consumed, or forcing communities to find other water sources. glacier mass change in Alaska using the Python Glacier Evolution Model (PyGEM) David Rounce, Regine Hock 12:00 - 15:45Lunch & ski break 15:45 - 16:15Coffee break 16:15 - 17:00 Poster introductions (1-2 slides and max.

GitHub is home to over 50 million developers working together to host and review code, manage projects, and build software together. “We are able to assess changes in glacier mass and runoff at an unprecedented scale.”. This allowed the team to estimate the decline in ice mass – the quantity of ice in terms of “weight,” or heft – for each glacier; reassembling these estimates into a regional mosaic yielded broad coverage of a vast glacial area as well as forecasts for smaller zones within it. Double Sliding Patio Door Clear Low-E Usage: PyGEM is meant for large-scale glacier evolution modeling.
