A number of floating ice shelves in Antarctica are at risk of disappearing entirely in the next 200 years, as global warming reduces their snow cover.
Three high-school students and a teacher from Wisconsin will participate in a joint pilot program of the US and Chilean Antarctic programs that will send them to a Chilean research station this February for hands-on experience with Antarctic environments and ecosystems research.
By carefully analyzing a 150-year-old moss bank on the Antarctic Peninsula, researchers reporting in Current Biology, a Cell Press publication, on August 29 describe an unprecedented rate of ecological change since the 1960s driven by warming temperatures.
The largest remaining Antarctic ice shelf contains several cracks and crevasses that could make it prone to collapse, but areas in which different types of frozen water blend together to create areas of bendable ice that help hold it together, according to a new study presented late last week.
The Antarctic Peninsula has been continually shrinking for centuries, since long before the Industrial Revolution, according to an international team of researchers.
Scientists report in the journal Nature that an Antarctic ice sheet may start to melt rapidly in this century.
As ESA’s Envisat satellite marks ten years in orbit, it continues to observe the rapid retreat of one of Antarctica’s ice shelves due to climate warming.
