Melting Antactic Ice May Not Create Global Catastrophic Sea Levels

Many studies reveal how melting ice that includes glaciers and ice sheets in Antarctica can cause unprecedented rising sea levels however, some scientists still believe that this melting may not lead to any disastrous and deadly events in the near future or are not "realistic".
In this new study, findings reveal how sea levels are most likely to rise at a range of 10 centimeters by the year 2100 even if greenhouse gas emissions are spewed at a medium or high rate in the atmosphere.

Previous estimates show that sea levels will rise by 30 centimeters or more however, this new research states that this rising only has the possibility of one in 20 chances of happening.
According to lead author of the study, Tamsin Edwards from the UK Open University, the Antarctica bed is crucial for the current status of the ice sheet however, there are bumpy or rough parts in the ice sheets that are apparently not sloping for this melting to happen immediately.
This new study applies real world physics in relation to the shape of the continent's bedrock and ice cap movement, including satellite observations that are able to monitor continent changes.
Researchers say that this new study is different compared to other simulations as the team utilized present day conditions to determine these new data predictions.
Edwards adds that many studies included numerous computer simulation models before, however these past studies have not compared their data to present day factors, without reassessing these aspects for their predictions.
This new approach also significantly marked down high impacts of the melting rates of Antarctica ice sheets, that challenges the past experiments that predicted that sea levels will rise to half or a full meter high by 2100. Researchers also believe that a catastrophic event could happen but this is more likely within 200 years.This new study is published in the journal, Nature.
