Researchers have discovered a new understanding of how climate change and warming oceans are shrinking Antarctic ice shelves.
The ice shelves are disappearing faster than first thought and are melting from the bottom, shedding icebergs more frequently.
They have been monitoring the calving, which is when ice shelves split and shed ice.
The latest research used satellite images of the entire Antarctic coastline. Thousands of satellite images have been taken to show the actual change of the ice front.
Smaller ice shelves are thinning rapidly and are becoming vulnerable to the warm water that’s melting underneath.
The icebergs are measured in gigatonnes, 1,000 million tonnes of ice. In terms of an ice cube, it’s an ice cube that is one kilometre in each direction.
Decay of the ice shelves increases the rate at which ice flows from Antarctica into the ocean.
All of this melting will cause the sea level to rise, which is a problem we may face in the future. It is predicted that the melting ice sheets could raise sea levels by as much 18.5 centimetres over the next 100 years.
