The frozen coastline of a Canadian Arctic island is eroding at up to a metre a day as a warming climate leads to longer summers, new research has found.

Researchers say the rate of collapse they found is six times faster than the average for the previous 65 years.

“Big chunks of land were breaking away and waves were eating them away,” said the study’s co-author Isla Myers-Smith, a geoscientist at the University of Edinburgh. “They were often gone by the next day.”
