An iceberg the size of the Spanish island of Majorca has broken off the coast of Antarctica, with measurements taken from satellites and planes confirming it’s now the world’s largest. Iceberg A-76 calved from the western side of the Ronne Ice Shelf in Antarctica and is now floating on the Weddell Sea, the European Space Agency said. It measures around 170 kilometers (105 miles) long and 25 kilometers (15 miles) wide. That’s larger than New York’s Long Island and half the size of Puerto Rico.
Last year, currents took iceberg A-68A, the world’s largest at the time, from Antarctica to the coast of the South Georgia Island. Scientists feared the berg would collide with an island that’s a breeding ground for sea lions and penguins, but it ended up splitting and breaking into pieces instead.
Average sea levels have risen about nine inches since 1880, and about a quarter of that increase comes from ice melting in the Greenland and Antarctica ice sheets, along with land-based glaciers elsewhere, according to a study published in Nature earlier this month.
