RS imagery reveals global warming’s latest victim

Toronto, Canada: Global warming has consumed another victim in the form of Canadian ice shelves, revealed a new study conducted by Canadian researchers.
Two ice shelves that existed before Canada was settled by Europeans diminished significantly this summer with one nearly disappearing altogether.
Luke Copland is an associate professor in the geography department at the University of Ottawa who co-authored the research. He said the Serson Ice Shelf shrank from 79.15 square miles (205 square kilometers) to two remnant sections three years ago, and was further diminished this past summer.
Copland, who uses satellite imagery and who has conducted field work in the Arctic every May for the past five years, said since the end of July, pieces equaling one and a half times the size of Manhattan Island have broken off. Co-researcher Derek Mueller, an assistant professor at Carleton University’s geography and environmental studies department, said the loss this past summer equals up to three billion tons. Copland said their findings have not yet been peer reviewed since the research is new, but a number of scientists contacted by The Associated Press reviewed the findings, agreeing the loss in volume of ice shelves is significant.
The loss is important as a marker of global warming, returning the Canadian Arctic to conditions that date back thousands of years, scientists say. Floating icebergs that have broken free as a result pose a risk to offshore oil facilities and potentially to shipping lanes. The breaking apart of the ice shelves also reduces the environment that supports microbial life and changes the look of Canada’s coastline.
