Climate change around Antarctica can severely affect Australia’s rainfall and even influence the distribution of wet and dry zones across southeast Asia, an international study has revealed.

Can crab shells provide a "green" solution to malaria?
A non-toxic mixture of chitin-rich crab shell powder and nanosized silver particles could be an environmentally friendly way of curbing the spread of disease-carrying mosquitoes, and malaria in particular. This is according to a series of experiments led by Jiang-Shiou Hwang of the National Taiwan Ocean University. The findings are published in Springer’s journal Hydrobiologia.
More natural dust in the air improves air quality in eastern China
Man-made pollution in eastern China's cities worsens when less dust blows in from the Gobi Desert, according to a new study published May 11 in Nature Communications.
Teleconnection between the tropical Pacific and Antarctica
In April 2016, a large-scale breakup of land-fast ice was observed in Lutzow-Holm Bay near Syowa Station, a Japanese research facility. It was the first comparably large calving in the region since 1998. Land-fast ice is sea ice that grows along the Antarctic coast and does not move much once formed. Syowa Station is normally surrounded by land-fast ice, which makes it very difficult for even an icebreaker to reach.
Irreversible ocean warming threatens the Filchner-Ronne Ice Shelf
By the second half of this century, rising air temperatures above the Weddell Sea could set off a self-amplifying meltwater feedback cycle under the Filchner-Ronne Ice Shelf, ultimately causing the second-largest ice shelf in the Antarctic to shrink dramatically. Climate researchers at the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI), recently made this prediction in a new study, which can be found in the latest issue of the Journal of Climate, released today. In the study, the researchers use an ice-ocean model created in Bremerhaven to decode the oceanographic and physical processes that could lead to an irreversible inflow of warm water under the ice shelf - a development that has already been observed in the Amundsen Sea.
Warmer temperatures cause decline in key runoff measure
Since the mid-1980s, the percentage of precipitation that becomes streamflow in the Upper Rio Grande watershed has fallen more steeply than at any point in at least 445 years, according to a new study led by the National Center for Atmospheric Research (NCAR).
