PPT-EARTH SCIENCE JOURNAL Sea ice

Have you ever wondered Why are there so many terms for ice Why can you walk on the North Pole Will I be able to walk on ice in the future Why should I care about such a cold place How does climate in one region of the world effect climate in another. Decline in the extent and thickness of Arctic sea ice is an active area of scientific effort and one with significant implications for ecosystems and communities.. Forecasting for seasonal timescales (i.e., the summer and into fall) is of particular interest to many stakeholders.. Bates et al., (2006). Stephens and Keeling (2002). Sigman. et al., (2010).

McLendon. 11/6/2015. 2. The Arctic hasn't been itself lately. Temperatures there are rising at twice the global rate, sparking an array of changes unlike anything in recorded history. One of the most striking examples is the region's sea ice, whose dramatic decline over the past decade has led to forecasts of an ice-free Arctic Ocean as early as the 2030s. . Objective. The Los Alamos Sea Ice model has a number of input parameters for which accurate values are not always well established. . We conduct a variance-based sensitivity analysis . of hemispheric sea ice properties to 39 input parameters.
