Did you know global sea levels have surged by 90mm in just 30 years? Researchers at PolyU used satellite laser tech to track the change, and it turns out most of the rise is from melting land ice—especially in Greenland. The pace is picking up, too, which is a big red flag for climate change. This new data could help predict future sea-level scenarios. Wild how much the planet is changing, right? #Science #ClimateChange #SeaLevelRise
