Sea level rising - we are all doomed

BBC NEWS | Science/Nature | Sea level rise 'is accelerating'

Global sea levels could rise by about 30cm during this century if current trends continue, a study warns.
Australian researchers found that sea levels rose by 19.5cm between 1870 and 2004, with accelerated rates in the final 50 years of that period.

A 20th century acceleration in global sea-level rise

A quick look at the abstract shows he has been busy "reconstructing" lots of data, and he has been at it for years. Strangely he doesn't seem to have taken a walk out of his office down to the harbour, I mean Tasmania can't be that big, can it? Because the late, sadly missed John Dalyon his website points out a few errors in this theory and provided evidence in Tasmania, and back in 1999 the BBC picked up on it.

Is this the picture that takes the heat out of global warming? It shows an Ordnance Survey Bench Mark engraved into a rock face on a little island near Port Arthur, Tasmania.
It was put there in 1841 by the famous Antarctic explorer Captain Sir James Clark Ross and amateur meteorologist Thomas Lempriere to mark mean sea level.
What is so fascinating is that the mark appears to some to be 30 centimetres above the current mean sea level. Scientists who are sceptical about the existence of global warming say it clearly undermines oft-repeated claims that sea levels have risen over the past century because of rising temperatures on Earth.
"This is the oldest known such bench mark in the world," says greenhouse dissenter John Daly, who took the photograph. "Ross put it in an ideal location which is both geologically stable and open to the vast Southern ocean, with no local estuary effects to distort the tides."
The benchmark - a broad arrow containing a horizontal line about 20cm long - was cut into a sandstone cliff on the Isle of the Dead, so-called because it was used as a cemetery for dead convicts.
It has been the subject of intense scientific scrutiny in the last few years. Australia's Commonwealth Science and Industry Research Organisation (CSIRO) have resorted to satellites, sophisticated tidal gauges, and precision surveying to measure sea levels in the local area today.


It's now 27 April (3 months down the track) and it doesn't look as if many (any?) people are interested in John Daly's pathetic attempts to "prove" that sea level is actually falling.

You could also look at some of the recent papers which indicate quite clearly that global sea level has risen significantly over the past century. If you don't like John Church's publications, try: Holgate and Woodworth, 2004. GRL, Vol. 31, L07305, doi:10.1029/2004GL019626.

There is no comments because not to many people know about this mark which is 30 cm higher than the mean sea level. the main stream media like to report on fear not facts. Satalites which measure air temp also prove there is very little warming contrast to ground measurements...
