Greenland has lost 3.8 trillion tonnes of ice since 1992. The reduced ice cover has caused the sea level to rise by 10.6 millimeters – and the ice is now melting more than seven times faster than they did almost 30 years ago. Nowadays, 254 billion tonnes of ice are lost annually in Greenland, compared with 33 billion tonnes in the 1990s. If the ice cover continues to melt at the same rate, 400 million people will suffer annual floods by the end of the 1990s.
