Satellite analysis has revealed two ice caps in the Arctic have completely disappeared.

They’re victims of human-caused warming, according to the National Snow and Ice Data Center.

Mark Serreze, director of NSIDC, researched Canada’s St. Patrick Bay ice caps in the 1980s when he was a student.

They used to be located on the Hazen Plateau of Canada’s Ellsmere Island.

Now all Serreze has left of them is a few photos.

The disappearance of the ice caps was confirmed by NASA’s Terra satellite.

Discover reported on Serreze’s shock at how quickly they vanished.

He said: “When I first visited those ice caps, they seemed like such a permanent fixture of the landscape.

“To watch them die in less than 40 years just blows me away.”

He first visited the ice caps in 1982 but published a paper in 2017 predicting they would disappear in less than five years.

Unfortunately, him an his colleagues were right.

A post on the NSIDC website explains: “In 2017, scientists compared ASTER satellite data from July 2015 to vertical aerial photographs taken in August of 1959.

“They found that between 1959 and 2015, the ice caps had been reduced to only five percent of their former area, and shrank noticeably between 2014 and 2015 in response to the especially warm summer in 2015.

“The ice caps are absent from ASTER images taken on July 14, 2020.”

In 1959 the ice caps measured in at 2.8 square miles and 2.93 square km (1.1 square miles) respectively.

That means the larger of the two was just over two times as big as Central Park in New York.

Serreze told Discovery: “It was like watching a sick friend slowly waste away from some awful disease.

“I knew the end was coming, but still couldn’t be completely prepared for it.”

The ice caps at St. Patrick Bay were part of a the Hazen Plateau were believed to date back to the Little Ice Age.

The Little Ice Age was a period of cooling between the 14th and 19th centuries.

The ice caps that remain in the area are melting less quickly but experts still think they are doomed.

Serreze told Discovery: “Climate change is very, very real, and as long predicted, the Arctic is leading the way.

“We are geoengineering our planet, and we don’t seem to want to accept that we’re headed for a very different world.”
