Decreasing rates of sea surface temperatures (SST) in summer and their increasing rates in winter in Tokyo Bay, Japan from 1976 to 1997 attain 1.5°C per decade - 30 times greater than the global SST increasing rate of 0.5°C per century. Such large SST changes resulted from intensified estuarine circulation in Tokyo Bay due to increased fresh water discharge due to increased water use on land and decreased tidal amplitude attributable to large-scale reclamation. Direct anthropogenic effects are much greater than the global warming effect on SST change in coastal seas.
