It is estimated that over two decades of Antarctica has been losing ice sheet rapidly, concerns arising from other ice sheet regions may also be disappearing in the future. Model projections of future Pine Island glacier in Antarctica have uncertainty, there are many unanswered questions that need to spend time and persistence to analyze sea level rise in the future.
Changes in Antarctic glacier
has provided evidence of past ice sheet changes that will help scientists to predict the likelihood of subsequent changes. Team of geologists using highly sensitive dating technique to track the thinning of Antarctic glaciers
, particularly the Pine island, where the results show last ice thinning has also been going on for decades in 8000 years ago.
According to Joanne Johnson of the British Antarctic Survey (BAS), their data depicting the history of Pine Island glacier in Antarctica in greater detail than ever before. Facts obtained signify rapid thinning of ice in the past and how sensitive the impact to environmental changes. Small changes could result in a dramatic situation and last a long time, maybe Antarctica would lose ice in a period of time much longer.
Professor Mike Bentley from Durham University said, the paper is part of a wide range of international scientific efforts to understand the behaviour of this important glacier. The results we’re publishing are the product of long days spent sampling rocks from mountains in Antarctica, coupled to some exceptionally precise and time-consuming laboratory analyses. But the result is very clearly demonstrated that depletion of ice sheet and Antarctic glaciers are very sudden happened 8000 years ago, just as is happening right now.
