The ice that forms around Prince Edward Island shores has been changing in recent winters. The last two years had lighter ice conditions than historic norms. The ice was thicker this winter but didn't form until February, almost six weeks later than it used to. Researchers say ice provides a protective shield against winter storms and erosion, so a shorter season is a concern. CBC’s Nancy Russell and drone pilot Aaron Adetuyi headed to the shore for more on the story.
