Greenland Ice Sheet has already caused nearly five metres sea-level rise

The researcher team lead from the Technical University of Denmark (DTU) revealed the sea level rise, which caused by the melting Greenland ice. According to the data of the author Shfaqat Abbas Khan, melting has caused 4.6 metres in the last 23,000 years.

Danish scientists have calculated accurate figures of the sea level rise due to a melting of the Greenland ice sheet. Over last 23,000 years, the level arose on 4.6 meters. The results of their new research Shfaqat Abbas Khan and his colleagues published in the journal Science Advances.

The researchers have calculated how much sea level rise will occur in the future, they were interested also in which coastal areas may soon be inundated by the sea.

“We have satellite measurements and aerial photos that show us how much of the Greenland ice sheet has retreated over the last 20 to 100 years, but to get a complete picture of the ice sheet’s influence on future sea levels, we need to go further back in time and look at present day sea melting in relation to the past.”

“We can do this with these results that show where the most powerful ice melt has occurred over time,” says Khan.
