Ecological Responses to Climate Change on the Antarctic Peninsula
From American Scientist
The crack of an iceberg splitting away from the Marr glacier reverberates through the halls of the Bio Lab at Palmer Station, on the western shore of the Antarctic Peninsula. That sound has grown increasingly familiar ....
The retreat of the Marr glacier ... signals ongoing environmental change. The average midwinter temperature here has increased by 6 degrees Celsius since 1950; this is the highest rate of warming anywhere on the planet, five times the global average.
The isolated biological community of the peninsula and its coastal waters evolved in a polar climate that remained relatively stable for many millennia. Now, as the climate shifts, [scientists] are trying to document and understand how the ecosystem responds.

VIDEO: How Hair Ice Grows
In 2013, American Scientist featured an article on odd ice formations on plant stems, including these curling ribbons of ice. One of the types of ice discussed in the article was hair ice—long, thin strands of ice that grow under quite specific conditions. The only problem is that a new study shows the theory put forth at the time—that gas pressure pushes the water out—isn’t correct... (click the link above to read more).
