High tide at Fort Denison in Sydney Harbour
You can see that if the sea is rising, it's not rising very much. More evidence that the alarmist figures put out by the climate bigots are a crock. Al Gore prophecies rises of several metres
There has in fact been some rise over the 128-year-long tide gauge record. Since 1886 it indicates a long-term rate of sea-level rise of two and a half inches (6.5cm) a century. That's hardly enough to knock anybody off their horse.
But wait! There's more! Here is a plot of the rise:
You can see that the sea level has been plateaued since 1950 -- exactly the time that the climate bigots say global warming began. So NONE of the rise was due to global warming. The small amount of global warming we appear to have had in recent decades did not shift the sea level one iota. Fun!
