Sea levels could be around a meter (3.3 feet) higher and the Arctic could be ice-free in the summer by 2100, the UN’s climate science committee has concluded.
Sea-level fears: This is 10 centimeters (3.9 inches) higher than the Intergovernmental Panel on Climate Change predicted six years ago. The change is because Antarctica is melting faster than expected. The revised estimate could be hugely significant to the 600 million people around the world who live less than 10 meters above sea level. It also suggests that countries urgently need to start spending money to shore up sea defenses, as the Global Commission on Adaptation recently warned.
