Satellite images show Etzberg is larger than Seattle, away from the Antarctic glacier

Satellite images from the European Space Agency show Tuesday when an iceberg erupted from an avalanche in Antarctica on Tuesday. Connected, the images show how the size of the big cities and smaller countries – the icebergs – split rapidly into the sea due to the changing climate of the world.

For more than three years the images combine with timeline animation by Adrian Luckman, satellite imaging glycologist and professor of geology at Swansea University in Wales. Together, they show three big calving events – the word for some parts of intact ice to split into the ocean over the past three years.

The animation begins on June 27, 2017, and ends this week on February 11, 2020, when the most recent calving takes place.

Satellite images without any reference point can make it difficult to imagine this huge ice-shaped concept. For measurements, Calving on Tuesday made Iceberg bigger than the city of Seattle, Washington is twice the size of DC, Same size as Las Vegas, About the size of Atlanta, And Almost the same size as the Malta nation.

Pictures taken just a few miles from the glacier of the polar marine scientist Richard Lauter show how close the ice is Ice pressed wall. Accordingly, the average thickness of the iceberg’s “floating ice front” is about 500 meters European Space Agency.

The area was broken off from Pine Island Glacier in Antarctica, which helps connect the western Antarctic ice sheet to the sea, the agency said.

According to the UK, it is usually difficult to capture calvings Center for Polar Observation and Modeling. Because most of the processes that drive natural events are hidden underwater, and satellites usually pass overhead at one go, often losing moment of action.

Pine Island, however, is shrinking rapidly. According to the agency, its rapid split has created one of Antarctica’s “intensive and extensive investigative avalanches.”

Intense focus on Pine Island led scientists to identify “growing cracks” in satellite images of glaciers Last year. “Since then, scientists have been keeping a close eye on how cracks were growing,” the company wrote.

Along with neighboring Thoyette Glacier, Pine Island has consistently lost ice for the past 25 years.

“Satellites have established a barthole whereby people can see these national events in remote parts of the world,” Says Mark Drinkwater, A veteran scientist and expert in Christophe’s.

After Tuesday’s historic calm, Iceberg breaks into several smaller pieces. What these pieces will do to the overall sea level rise remains unknown. However, Lutter warned on Twitter That iceberg is “part of an ice shelf at the terminus of an icy iceberg” enough to raise the sea level to more than 0.5 meters (1.5 feet above). And, according to the European Space Agency WebsiteIce erosion from Pina Island has already “contributed more to sea-level rise over the past four decades than any other glacier in Antarctica.”

The Antarctic Peninsula is one of the fastest warming places on earth. The weather was sunny and one of the early on the peninsula in the first week of February Record breaking is 64৪.5 degrees Fahrenheit – Warmer than most Texas.

New research The release in December indicated that “Antarctica is extremely vulnerable to projected increases in sea temperatures and may continue to have ice-climatic feedbacks that exacerbate warming.”

According to Drinkwater, “the worrying thing is that the daily data stream reveals the dramatic momentum where the climate is redefining Antarctica’s face.”
