'Earth has lost over 12 trillion tonnes of ice in 47 years'
About 12.5 trillion tonnes of ice have melted from polar regions since 1979. Warmer ocean waters are causing five-sixths of this significant ice sheet melt. This accelerated melting poses a serious threat to global sea levels. Coastal regions worldwide will experience increased vulnerability due to rising waters. Scientists report the polar ice sheets are melting away at a fast pace.
