2 . A huge section of the Milne Ice Shelf, located on Ellesmere Island in the northern Canada, collapsed into the Arctic Ocean, according to the Canadian Ice Service. This created an “ice island” which is about 30 square miles in size. As a comparison, Manhattan Island is about 23 square miles.
“Entire cities are that size. These are big pieces of ice,” Luke Copland, a glaciologist at the University of Ottawa who was part of the research team studying the ice shelf, told Reuters. “This was the largest remaining intact (完整的) ice shelf, and it’s collapsed, basically. ”
The Canadian Ice Service said on Twitter that “above-normal air temperatures, offshore winds and open water in front of the ice shelf are all part of the recipe for the ice shelf to break up.” A huge section of the Milne Ice Shelf has collapsed into the Arctic Ocean, producing a 30-square-mile ice island.
The ice shelf has now been reduced in area by about 43%. An ice shelf is a thick slab of ice, attached to a coastline and extending out over the ocean, according to the National Snow and Ice Data Center. “Some shelves have existed for thousands of years,” the center said.
So what’s going on up there? Though the planet is warming worldwide due to climate change, the Arctic has been warming at a rate twice that of the rest of the world. This summer has been particularly warm: Arctic sea ice melted to its lowest July level on record and in June, a town in Siberia soared (急升) to 100.4 degrees Fahrenheit, believed to be a record high for the Arctic.
“When I first visited those ice caps, they seemed like such a permanent fixture of the landscape,” Mark Serreze, director of the NSIDC and geographer at the University of Colorado, Boulder, said in a statement. “To watch them die in less than 40 years just blows me away.”

7 . Malin Pinsky had the first of two lightbulb moments in 2003 while crossing Drake Passage. He was then standing on the bridge of a research ship and was scanning the sky for seabirds, which was one of his duties as a research technician on the cruise (海上航游). Just five months earlier he had finished college, where he studied biology and environmental science.
As the ship entered nutrient-rich Antarctic waters, whales suddenly showed up all around the ship. That moment on the bridge helped him realize that the ocean looks featureless from the top, but there’s so much going on underneath.
The second lightbulb moment hit him several months later. Pinsky was then an intern (实习生) in Washington, D.C. His job was making photocopies. It was around the time when two big reports had come out. Both focused on what policies might best preserve U.S. ocean resources. “I realized we have all these laws and policies that determine how we as a society interact with the ocean. But they’re far out of date. We don’t yet have the science to know what the new policy should be,” Pinsky said.
Today he runs a lab with about 20 workers. His team wants to seek how our changing climate, as well as overfishing and habitat destruction, might be driving changes in fish and other animals in the sea. To find out, team members travel each year to coral reefs near the Philippines. There, they carefully catalog populations of different fish. They collect data on the growth and mating of these fish, their diversity and other factors.
“Pinsky’s broad approach to the problem — looking at species, where they live and how fisheries are managed — is setting the pace for other scientists,” says Kimberly Oremus, a fishery economist at the University of Delaware in Newark. “Pinsky is pushing the whole field to respond to his growing body of research.”
