Some climate researchers are saying post-tropical storm Fiona may have been historic, but it’s also a sign of what’s coming.
Federal summaries of international climate science have noted since 2019 that the intensity of tropical storms that form in the southern Atlantic and head north to the Canadian coast are likely to increase as waters warm.
Anya Waite, a professor of oceanography at Dalhousie University,says the “sobering” reality is the warmer water shoots heat and moisture into storms like Fiona, helping them last longer and travel over a wider area.
While utility spokespeople referred to Fiona as “historic” in their news releases, Waite says storms of this magnitude aren’t going away.
She says their ability to endure is partly because of the surface water being warmer off the Atlantic coast.
