Rising Sea Levels Due to Greenland's Ice Loss Can Exponentially Increase Global Flood Risk

According to a new study released on Monday, Greenland's ice sheet has melted by 3.5 trillion tonnes in the last decade, raising global sea levels by one millimeter and increasing global flood risks.

Predicting how much Greenland's melt will contribute to increasing sea levels is notoriously difficult for scientists, especially when other land-based glacier melt is considered.

Water expands when oceans warm, contributing to increased sea levels.

According to the study's authors, the satellite data allowed scientists to determine how much ice Greenland lost in a given year and convert it to sea-level rise equivalents swiftly and reliably.

According to co-author Amber Leeson, senior professor in Environmental Data Science at Lancaster University in the United Kingdom, "model projections show that the Greenland ice sheet will contribute between 3-23 cm to global sea-level rise by 2100."

"These new spaceborne runoff estimates will help us better comprehend complicated glacier melt processes... and simply allow us to update our future sea-level rise forecasts."
