Governments and citizens should move more swiftly to protect coastal buildings and vital transport links, flooding experts say.
Worrying figures released this week on the rising seas in Atlantic Canada should prompt governments and citizens to move more swiftly to protect coastal buildings and vital transport links, flooding experts say.
Blair Greenan, a federal oceanographer who oversaw the oceans chapter of the report, said in an interview that without any adaptation measures, flooding during Halifax storms will be noticeable in just a decade as relative sea level goes up about 10 centimetres. “That is what is going to happen,” he said, adding that he has attended the most recent G20 meetings and has heard no firm commitments from nations that they will even meet goals set in the Paris Accord.The federal study also highlights the vulnerability of the Chignecto Isthmus — a low-lying, 20-kilometre band of land which joins Nova Scotia to New Brunswick, said Feltmate.
After options are presented, the governments must agree on the way forward and how much they will spend. All of the options presented in a 2016 required at least five years to complete.“This report should put action on adaptation on steroids for a response to this. We have to act quicker than we currently are.”Nancy Anningson, the coastal adaptation co-ordinator of the Ecology Action Centre, says part of the response to sea level rise is stricter building rules and the preservation of wetlands.
Her organization has set up a website titled www.sealevelrise.ca to give building owners a place to gather basic information.Jason Thistlethwaite, a professor of environment and business at the University of Waterloo, says all Canadian jurisdictions also need to rapidly begin providing easily accessible flood risk maps for citizens.
