We don't use a large % of our current water.
If you compare to the Colorado river which 90% of the water is used before it hits the Mexican boarder we don't have any issues even if we only have Snow melt without glaciers.
Forest fires will also decrease once we burn though the old forests in Alberta. Years of firefighting as opposed to letting things burned have help to create the issues we are now facing. Young post fire forests will be much more resistant to burning than current forests. This could take a while though.
Our biggest risks will be drought affecting agriculture otherwise we make it through climate change in fantastic shape.
