According to researchers, glaciers – massive blocks of moving ice – located along the coast of Antarctica are flowing faster during the summer due to a combination of melting snow and warmer ocean temperatures. On average, the glaciers travel at around one kilometer (0.6 miles) a year. But

On average, the glaciers travel at around one kilometer a year. But a new study has found a seasonal variation in the speed of the ice flow, which speeded up by up to 22% in summer when temperatures are warmer. This gives an insight into the way climate change could affect the behavior of glaciers and the role they could play in raising sea levels.

It is estimated that between 1992 and 2017, meltwater from the glaciers increased global sea levels by around 7.6 mm. How that may change in the future is one of the big uncertainties in modeling climate change.
Along the west coast of the peninsula, the glaciers drain ice from the ice sheet directly into the Southern Ocean.
