Researchers in Antarctica have discovered that the frozen continent’s ice shelves produce an audible sound when the wind passes over the surface snow, a haunting song from a landscape that remains alien to the majority of us. The researchers also found that the "song" changes as the surface conditions of the ice changes — meaning that this Antarctica aria might become useful in tracking the effects of climate change on the ice at the bottom of the Earth.

Deadly wildfires are raging around the globe again this year, driven by heat waves and dry conditions exacerbated by global warming. Major fires in Australia, Europe, North America and Russia have prompted states of emergency and calls for assistance from the international community, and the conditions in Sweden have resulted in wildfires occurring north of the Arctic Circle.

East Antarctica’s Totten Glacier has been revealed to be more unstable than previously anticipated. New research has found that portions of the glacier that were thought to be on stable ground are actually floating on seawater, prompting concerns over the ice sheet’s stability, and its potential to significantly contribute to the acceleration of sea level rise.

Totten Glacier is a flowing ice field that is more than three-quarters the size of Texas, and holds a massive volume of ice that could raise sea levels by 3.5 meters (11.5 feet) if it were to completely melt.

Last week, temperatures in the Arctic once again went above freezing, following a split in the Polar Vortex that allowed warm air currents to flow into the region, with some stations recording temperatures 25ºC (45ºF) above normal. This event accompanies an abrupt retreat of sea ice in the Bering Sea, having lost almost one-third of its coverage in just over a week.
