NEW YORK – The ice sheet is melting at an unprecedented rate, according to the United Nations.
The United Nations’ climate change chief said Monday the rapid rate of ice loss over the past year has resulted in an “extremely large” loss of ice.
The world is experiencing a “very unusual” global change, said U.N. climate chief Christiana Figueres, after a meeting with her British counterpart, Sir Andrew Green.
Figueres said the loss of the ice sheet in the Antarctic and Greenland has led to a “substantial acceleration” of global warming, which could have significant impacts on the global economy.
In addition, she said, the loss is likely to increase sea levels and “threaten global health.”
Ice sheets are composed of ice crystals and ice floating on the ocean floor, which form as ice melt in the summer months.
Scientists have been worried about this ice sheet melting in recent years, but this year has been unusually cold and ice is forming all over the world.
Ice sheet melt is also occurring in other parts of the world, including the Pacific Ocean, and in the Arctic.
Ice in the ice sheets is a key driver of sea level rise and warming.
It also contributes to sea level rises in the world’s oceans, which can also cause flooding and erosion.
