The rise in sea levels is SLOWING – making a total mockery of the IPCC models
In March 2010 I noted that sea levels have constantly changed through the history of the Earth, and indeed, we have direct evidence from cities like Dwarka which went below the sea (true, that could have been a local phenomenon due to local sinking of land – so that's a mere hypothesis at the moment).
Then, in January 2011 I highlighted evidence that shows that there has been no accelerating trend in the rise of sea levels – something that is critically necessary in order to confirm the models that IPCC uses.
Both these blog posts cited plenty of scientific studies. I did not make these up.
And now the FINAL NAIL IN THE COFFIN OF IPCC (actually it is already dead as a dodo): Sea-level rises are slowing. (I'm reproducing the entire post from The Australian, below).
Note that I don't ever bother about people's opinions and don't report on, or discuss opinions – which unfortunately flood the comments sections of most newspapers. Because of my extensive science background and study of the scientific method I look PURELY for evidence. Hard evidence is the bedrock of the scientific approach, not models! (I know that also very well, since I know a lot about the most sophisticated economic models in use today – which are essentially PURE garbage).
Models are just one's best guess, based on a mathematical representation of one's theories. But a) it is very hard to find the actual underlying mathematical equations to represent a theory – even if that theory is right, and b) it is very hard to find a correct theory in relation to complex matters like society and climate in the first place.
Just having a mathematical model that runs on a supercomputer doesn't make that model right. The results of the model MUST match data, else that model – and its underpinning theory – is immediately FALSIFIED. So far I don't know of ANY complex model that accurately mimics reality. All complex models in the world are therefore PURE garbage – works of fiction. We have a long way to go to get ANY prediction about the future right.
In brief, there is at present no combined, complex, theory of climate that has not been falsified. All these are hypotheses, discarded by the wayside.
Hence climate scientists are groping in the dark and are best advised not to impose their totally half-baked and fictional views on people.
IT IS A MINIMUM EXPECTATION OF MODELS THAT THEY MUST "PREDICT" ALL OBSERVATIONS OF THE PAST, AS WELL AS THE FOLLOWING YEARS' OBSERVATIONS. If a model can't predict the next year's data (ALL data including temperature, sea level, etc. etc.) then that model is FALSE.
That is the basic premise of science.
An brief, all models used by IPCC to base its predictions on are FALSE AND UNSCIENTIFIC.
That is now proven beyond the slightest iota of doubt.
The Australian July 22, 2011
ONE of Australia's foremost experts on the relationship between climate change and sea levels has written a peer-reviewed paper concluding that rises in sea levels are "decelerating".
The analysis, by NSW principal coastal specialist Phil Watson, calls into question one of the key criteria for large-scale inundation around the Australian coast by 2100 — the assumption of an accelerating rise in sea levels because of climate change.
Based on century-long tide gauge records at Fremantle, Western Australia (from 1897 to present), Auckland Harbour in New Zealand (1903 to present), Fort Denison in Sydney Harbour (1914 to present) and Pilot Station at Newcastle (1925 to present), the analysis finds there was a "consistent trend of weak deceleration" from 1940 to 2000.
Mr Watson's findings, published in the Journal of Coastal Research this year and now attracting broader attention, supports a similar analysis of long-term tide gauges in the US earlier this year. Both raise questions about the CSIRO's sea-level predictions.
Climate change researcher Howard Brady, at Macquarie University, said yesterday the recent research meant sea levels rises accepted by the CSIRO were "already dead in the water as having no sound basis in probability".
"In all cases, it is clear that sea-level rise, although occurring, has been decelerating for at least the last half of the 20th century, and so the present trend would only produce sea level rise of around 15cm for the 21st century."
Dr Brady said the divergence between the sea-level trends from models and sea-level trends from the tide gauge records was now so great "it is clear there is a serious problem with the models".
"In a nutshell, this factual information means the high sea-level rises used as precautionary guidelines by the CSIRO in recent years are in essence ridiculous," he said. During the 20th century, there was a measurable global average rise in mean sea level of about 17cm (plus or minus 5cm).
But scientific projections, led by the Intergovernmental Panel on Climate Change, have suggested climate change will deliver a much greater global tide rise in mean sea level this century of 80-100cm.
The federal government has published a series of inundation maps based on the panel's predictions showing that large areas of Australia's capital cities, southeast Queensland and the NSW central coast will be under water by 2100.
Without acceleration in sea-level rises, the 20th-century trend of 1.7mm a year would produce a rise of about 0.15m by 2100.
Mr Watson's analysis of the four longest continuous Australian and New Zealand records is consistent with the findings of US researchers Robert Dean and James Houston, who analysed monthly averaged records for 57 tide gauges, covering periods of 60 to 156 years.
The US research concluded there was "no evidence to support positive acceleration over the 20th century as suggested by the IPCC, global climate change models and some researchers".
Mr Watson cautioned in his research and again yesterday that studies of a small number of northern hemisphere records spanning two or three centuries had found a small acceleration in sea-level rises. He said it was possible the rises could be subject to "climate-induced impacts projected to occur over this century".
Mr Watson's research finds that in the 1990s, when sea levels were attracting international attention, although the decadal rates of ocean rise were high, "they are not remarkable or unusual in the context of the historical record at each site over the 20th century".
"What we are seeing in all of the records is there are relatively high rates of sea-level rise evident post-1990, but those sorts of rates of rise have been witnessed at other times in the historical record," he said.
"What remains unknown is whether or not these rates are going to persist into the future and indeed increase."
He said further research was required, "to rationalise the difference between the acceleration trend evident in the global sea level time-series reconstructions (models) and the relatively consistent deceleration trend evident in the long-term Australasian tide gauge records".
With an estimated 710,000 Australian homes within 3km and below 6m elevation of the coast, accurate sea-level predictions are vital for planning in coastal areas anticipating predicted sea-level rises of almost a metre by 2100.
