PPT-7 reasons why Arctic sea ice matters

The vanishing veneer of frozen ocean isnt just important for polar bears By Russell McLendon 1162015 2 The Arctic hasnt 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 regions sea ice whose dramatic decline over the past decade has led to forecasts of an icefree Arctic Ocean as early as the 2030s . 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.. Presentation by Kathleen Crane. Arctic Research, Climate Program Office.

Its Impact on Earth’s Spheres and Sustainability. What constitutes a Polar Ice Cap?. A Polar ice cap is a high-latitude region of land or water that is covered in ice.. Ice caps form as ice accumulates year after year. As part of a cyclical process, each year some of the ice melts in the summer, and then reforms in the winter. Wilco Hazeleger. www.esciencecenter.nl.

MAJOR THRUSTS:. By clearly identifying the arctic risks to submarine cables, the telecoms industry will hopefully be better prepared for future projects.. The technical means to reduce risks are available to the cable industry but the careful study of the project route initially through desk top study and site visit activities is essential. Done well, these activities will ensure key project decisions at an early stage are made on an informed basis and lead to a well-engineered and crucially, a reliable cable system.. AGU . Townhall.
