More than four trillion tonnes of ice from Greenland and Antarctica has melted in the past 20 years and flowed into the oceans, pushing up the sea levels, according to a study that provides the best measure to date of the effect climate change is having on the Earth’s biggest ice sheets.
The latest study combines past measurements to arrive at what the Associated Press called a new “scientific consensus” that Greenland is melting at a faster pace and that “as a whole the Antartic ice sheet is melting”. The following graph from Associated Press shows how melting polar ice sheets are increasingly contributing to rising sea levels, threatening coastal communities:
Prof Richard Alley, of Penn State University, US, who was not involved in the study, said: “This project is a spectacular achievement. The data will support essential testing of predictive models, and will lead to a better understanding of how sea level change may depend on the human decisions that influence global temperatures.” Rising sea level is one of the greatest long-term threats posed by climate change, threatening low-lying cities and increasing the damage wrought by hurricanes and typhoons.
