We all have been aware of the fact that rising temperature is causing melting down of Antarctica's ice sheets that can cause a huge rise in the sea level. Now a new study has given some new details on the melting of Antarctica's ice sheets.

As per experts, the warming temperature across the world is expected to make the vast kilometers-thick ice sheet grow unstable. Earlier models have shown that this ice sheet's collapse could cause as much as 50cm or even a meter of sea level rise across the world.

According to study, the sea level rise in the worst-case scenario will not be certainly more than 30cm, by the year 2100.

Study lead author Dr Tamsin Edwards, the Open University physicist who carried out the study along with Catherine Ritz from Université Grenoble Alpes, told BuzzFeed News that their new model gave two main predictions. The first is that the most likely outcome and the other is the upper limit, i.e. the worst-case scenario.

As per the study, the most-likely outcome is a sea-level rise of about 10cm. it is very much similar to the outcome suggested by the Intergovernmental Panel on Climate Change (IPCC).

According to Edwards, "There were a few studies that were giving quite pessimistic numbers, like half a metre, a metre".

Edwards also said that climate predictions are uncertain due to the huge number of variables involved. Their study tried to minimize this by running its computer model 3,000 times. No other study so far has tried this, she said.
