Russian Navy Confirms Emergence of Five New Islands in the Arctic Ocean

21 November 2019, by

The physical geography of the Arctic Ocean is evolving as climate change causes ice melt to reveal new islands and waterways in remote areas near the North Pole. The exposure of this new frontier will alter the behavior of Russia’s strategic militaristic forces as well as shift the geopolitical environment of the region in terms of shipping and resource extraction.

New Studies Trace Glacier Dynamics in the Grand Tetons

5 November 2019, by

In Grand Teton National Park, two groups of researchers are investigating glaciers from different, but complimentary perspectives. National Park Service scientists are tracking glacial melt on five of the park’s eleven glaciers while Washington State University biologist, Scott Hotaling, examines the effects of glacial meltwater on the microbiota downstream.

Huge Cracks in Antarctic Glacier Foreshadow Epic Calving Event

30 October 2019, by

The European Space Agency (ESA) released a video this past week showing the evolution of two very large and disconcerting cracks in Antarctica’s Pine Island Glacier. They have each grown to 20km in length and could shear off a hunk of ice the size of Paris and Manhattan combined.
