A study by Slawek Tulaczyk and Marion Bougamont reveals that the West Antarctic ice stream may slow down and stop moving altogether, leading to thinning and shrinking of the ice shelves. This could have dramatic consequences for global ocean circulation and climate.
Scientists have developed a new technique using ice-penetrating radar to study long-ago changes in West Antarctic ice streams. This allows them to look at changes much farther back in time, indicating possible fluctuations in the stability of the massive West Antarctic Ice Sheet.
A team led by MSU biologist John Priscu has discovered bacteria in an ice core from Lake Vostok, a subglacial body of water under the East Antarctic ice cap. The finding suggests that microorganisms can thrive in extreme environments, even under millions of years of isolation.
A new study suggests the West Antarctic Ice Sheet's complete disintegration in 7,000 years could be inevitable due to its potential instability. The ice sheet's collapse would raise global sea levels, flooding low-lying coastal regions and posing a significant threat to global climate patterns.
An international team of scientists analyzed satellite radar measurements, finding no significant melting or instability in the West Antarctic ice sheet's middle section. The study suggests the answer to whether global warming affects its stability is no, at least for now.
An ancient Antarctic ice core suggests a global climate-warming event occurred 12,500 years ago, with temperatures rising about 20 degrees Fahrenheit in a 50-year period. The findings challenge previous assumptions and throw new light on climate change research.
