More reasons to NOT speed up and rather slow down when it comes to climate risk mitigation policies that have been linked to flooding?:

Engineers, hydrologists, watershed managers, hydraulic engineers/modellers can explain flooding by increased hydrologic stresses (more pavement and more runoff) - changing rainfall is not the driver at all:

Historical land use development practices explain flooding, not changing climate and rain extremes - consider high risk developments like in Calgary right in the river floodway, or Gatineau with 75% of homes  in the "20 year floodplain", or Toronto island with flooding since the mid 1800's:

2017 Lake Ontario levels were only 5 cm above previous maximum levels - long term land leases in a high risk zone were real issue.
