Rise of Sea Levels "Greatest Lie ever told"


Rise of Sea Levels "Greatest Lie ever told"

'......as an expert reviewer on the IPCC's last two reports he discovered that not a single one of the 22 contributing authors was a sea level expert.......'

Dr Morner

For anyone living in London or Mablethorpe who has been considering buying a boat to cope with the imminent rise in sea levels that Al Gore has promised us: good news. London and Skegness are not about to be swept away by biblical floods. Nor are the seas going to rise up and swallow all those tiny Pacific islands; we are not going to suffer the same fate as Atlantis.

The revelation comes in Christopher Booker's Telegraph column focussing on the work of Nils-Axel Mörner, a physicist who has, for the last 35 years, been studying sea levels world-wide. Dr Mörner's conclusions? That "all this talk about the sea rising is nothing but a colossal scare story."

He asserts that the sea level has not risen for the last 50 years, and that if any rise does occur this century "it will not be more than 10cm." And how can he be so sure? Well, unlike most sea level studies which are based on computer modelling, Dr Mörner has actually headed out into the field to conduct his research.

One of his most shocking discoveries was the way the IPCC was able to show sea levels rising by 2.3mm a year: their experts had based the figure on a single tide-gauge in Hong Kong harbour showing a rise of 2.3mm. They then adjusted the entire global sea-level projection upwards by 2.3mm, creating an upward trend in the graphs. But we shouldn't really be surprised -- when Dr Mörner was asked to act as an expert reviewer on the IPCC's last two reports he discovered that not a single one of the 22 contributing authors was a sea level expert.

'Antarctic Ice is growing'

ANTARCTIC ICE GROWING, NOT MELTING AWAY

The Australian, 18 April 2009

By Greg Roberts

ICE is expanding in much of Antarctica, contrary to the widespread style public belief that global warming is melting the continental ice cap.

The results of ice-core drilling and sea ice monitoring indicate there is no large-scale melting of ice over most of Antarctica, although experts are concerned at ice losses on the continent's western coast.

Antarctica has 90 per cent of the Earth's ice and 80 per cent of its fresh water, The Australian reports. Extensive melting of Antarctic ice sheets would be required to raise sea levels substantially, and ice is melting in parts of west Antarctica. The destabilisation of the Wilkins
ice shelf generated international headlines this month.

However, the picture is very different in east Antarctica, which includes the territory claimed by Australia.

East Antarctica is four times the size of west Antarctica and parts of it are cooling. The Scientific Committee on Antarctic Research report prepared for last week's meeting of Antarctic Treaty nations in Washington noted the South Pole had shown "significant cooling in recentdecades".

Australian Antarctic Division glaciology program head Ian Allison said sea ice losses in west Antarctica over the past 30 years had been more than offset by increases in the Ross Sea region, just one sector of east Antarctica.

"Sea ice conditions have remained stable in Antarctica generally," Dr Allison said. The melting of sea ice - fast ice and pack ice - does not cause sea levels to rise because the ice is in the water. Sea levels may rise with losses from freshwater ice sheets on the polar caps. In Antarctica,
these losses are in the form of icebergs calved from ice shelves formed by glacial movements on the mainland.

Last week, federal Environment Minister Peter Garrett said experts predicted sea level rises of up to 6m from Antarctic melting by 2100, but the worst case scenario foreshadowed by the SCAR report was a 1.25m rise.

Mr Garrett insisted global warming was causing ice losses throughout Antarctica. "I don't think there's any doubt it is contributing to what we've seen both on the Wilkins shelf and more generally in Antarctica," he said.

Dr Allison said there was not any evidence of significant change in the mass of ice shelves in east Antarctica nor any indication that its ice cap was melting. "The only significant calvings in Antarctica have been in the west," he said. And he cautioned that calvings of the magnitude seen recently in west Antarctica might not be unusual.

"Ice shelves in general have episodic carvings and there can be large icebergs breaking off - I'm talking 100km or 200km long - every 10 or 20 or 50 years."

Ice core drilling in the fast ice off Australia's Davis Station in East Antarctica by the Antarctic Climate and Ecosystems Co-Operative Research Centre shows that last year, the ice had a maximum thickness of 1.89m, its densest in 10 years. The average thickness of the ice at Davis since the 1950s is 1.67m.

A paper to be published soon by the British Antarctic Survey in the journal Geophysical Research Letters is expected to confirm that over the past 30 years, the area of sea ice around the continent has expanded.

The working sea defences.













Just Click a photo to open it.






The impression given by the Bid is that our sea defences are weak and require a lot of money spent on them. This is bad for the area because it will affect insurance premiums, property values and the official attitude towards maintaining the defences.

I am not an oceanographer nor am I a horticultural expert either but I know what I know and what I can see. So lets look at these defences.

What the new officials will not know: When I first came here there were two wide concrete promenades, one below the other, with their own steps down to the beach. Some 15 or more feet high. (I have asked for plans to draw up a more precise picture). Millions of tons of granite rocks were brought over the North Sea by massive barges in an operation that went on for many months. These were stacked up against the bottom promenade to create a natural key and then millions of tons of sand was brought on to the beaches, literally covering all these rocks and the lower promenade to a level a few inches from the top of the upper promenade. This had the effect of pushing the sea back from the defences and even if reaching that far would thus only be a few inches of water instead of the powerful 10-15ft of water that had been battering the defences at every high tide before the work. It was common to hear this like a continuous express train from a mile away but no more. Now on the beach we can see flora and fauna and new dunes forming too well away from the defences. Surely this cannot happen under salt water. Maybe it can and maybe I am wrong. But in my humble opinion, it is all evidence of the success of the work and thus to maintain this will not require more than regular sand replenishment and maintenance. I have attached pictures of the new plant life so see for yourself. Some, as far as 50m from the promenade, and they must be preserved because they are binding the sand and stopping it from being displaced.
