An example of a sudden and rapid acceleration in the flow of glaciers towards the sea – A harbinger for rapid sea level rises.
According to a new study published in Nature Communications, the
Scientists at the University of Sheffield have discovered that they are 100% faster than average – up to 400 meters per year – for a period of several days multiple times per year.
The following new findings were discovered using imagery and data from satellites alongside regional climate modeling.

The new research shows the accelerations in Antarctic Peninsula glaciers' movements coincide with spikes in snowmelt.
When the meltwater penetrates the ice, it becomes the formation of glaciers, the more snow that melts on top of the glacier.
HOW DOES SURFACE MELTWATER AFFECT GLACIER MOVEMENT?
In a first-of-its-kind study, researchers have correlated the influence of surface meltwater on the movement of glaciers toward the sea.
by scientists, the glaciers are accelerating into the sea 100 percent faster than previously thought.
They could have drastic impacts on the rise of sea levels across the globe.
The study portends a frightening fate for the future of Antarctica and its glaciers, especially when coupled with recent findings on other glaciers like Thwaites.

The Thinning of the Shelf – the part of where the glacier meets and floats atop the sea – by warm ocean water could collapse.
Earlier this year, scientists have discovered global warming has caused the melting of the ice on the continent to increase sixfold since 1979.
This phenomenal rate of melting has more than half an inch – and Experts predict it will get worse.
Researchers have discovered that, between 1970 and 1990,
Scientists have predicted a 'multi-meter sea level rise from antarctica in the coming centuries' as a result of the vast loss of ice. The continent was shedding an average of 40 gigatons of ice mass annually.
Ultimately, researchers predict that glaciers on the Antarctic Peninsula will behave like those in present-day Greenland and Alaska, where meltwater controls the size and timing of variations in glacier flow across seasons and years.
The Antarctic Ice Sheet and its Contribution to Sea Level Rise.
In common with Antarctica.
'It's crucial that this f actor is considered in models of future sea level rise, so we can prepare for a world with fewer and smaller glaciers. '
According to Pete Tuckett, who made the discovery while studying for his Masters in Polar and Alpine Change at the University of Sheffield, the research is the first-of-its-kind to focus on Antarctica.
'Given that atmospheric temperatures, and there are surface temperatures, in Antarctica are predicted to increase, this discovery could have significant implications for the future.
