Arctic Sea Ice Reaches Another Record Low (March 2017)
Static Preview

Published on Mar 22, 2017

On March 7, 2017, Arctic sea ice reached its annual wintertime maximum extent, according to scientists at the NASA-supported National Snow and Ice Data Center (NSIDC) and NASA. The Arctic sea ice extent set a record low after a warm winter. Combining the Arctic and Antarctic numbers shows that the planet’s global sea ice levels on Feb. 13 were at their lowest point since satellites began to continuously measure sea ice in 1979.

Here is IPCC report, Summary for Policy Makers on Chapter Six, Oceans. (Update of April 2, 2014)

Inspired by the launch of the World Resources Institute's (WRI)  Global Forest Watch, Ruth Ann Barrett of EarthSayers.tv explores the concept of an Oceans Advocacy platform addressing the age old question, How Many fishes in the Sea, by bringing together oceans advocates in one spot and with access to databases, research, maps, voices of leaders and experts, including those proponents of a circular economy. A whole systems approach to problem solving - a sustainability awareness perspective.  

The goals and objectives of the OceansAdvocacy.com are detailed in the printed presentation available here.  A companion paper, On the Importance of Search: What EarthSayers.tv is Teaching Me is available here.

Melting Greenland Ice Sheets with Gordon Hamilton
Static Preview

Speed of glaciers march to the sea is tripling!

On the Kangerdlugssuaq Glacier -- one of Greenland's largest ice fields -- scientists measure the movement of the ice sheet as it transports frozen water to the ocean. They discover that the speed of the glacier's march to the sea has tripled in just ten years. Alarm bells sound because at the current melt rate, within a few decades rising seas will have a profound effect on the low-lying countries of the world. January 20, 2012 uploaded. Gordon Hamilton is a glaciologist working on ice sheet dynamics, and the role ice sheets play in modulating global sea levels.
