Rising ocean worse at river mouth: Report (Canada): The Fraser River delta faces the biggest rise in sea level this century of any part of B.C.'s coast, a provincial government report shows. Local relative sea level changes predicted for the decades ahead vary depending on geologic forces causing the ground to sink in some areas like the Fraser's mouth and rise in other places.

The findings predict sea levels in the Fraser delta will go up a minimum 35 centimetres by 2100 as a result of climate change and perhaps as much as 1.2 metres based on the extreme estimate for how high ocean levels may rise globally. The average climate change estimate calls for a 50-centimetre rise in the Fraser River delta. ...The loading of sediment into the Fraser delta is causing it to sink by one to two millimetres per year, the report says, and construction of big ferry and port terminals may be further compacting the ground by another millimetre a year....
