In the last month we've spoken many times about the poles and their critical envitomental situation due to the ice melting caused by the global warming.
This wonderful picture by John B Weller is a perfect chance to do it once again.
Not far from its Franklin Island colony, this lone Adelie punctuates the looping scrawl of penguin tracks across plates of Ross Sea pack ice. Some 2.7 million of the birds populate the Ross Sea region.
The Antarctic Summer has reduced the ice pack in a obstacle course like never before.
