Flick that chip off your shoulder. I was just heckling you. Hop off your high horse and come down and live amongst the rest of us proletariat. I couldn't give a fuying flock about topics that only 1% of the rest of humanity might even consider being interesting. Cheesy

When you finish displaying your superiority complex to everyone, you might want to consider that this post wasn't directed at you for response. But if you want to be my next punching bag, figuratively speaking, then I can make room on my schedule for you.

Well your original proclamation must have had some basis, you would think. The subject of Climatology is a tad more complex than the latest price of Santa Getrudis heifers at Gracemere, so if you have such a strong opinion on it, it stands to reason that you wouldn't have just snatched that particular pearl of wisdom from where the sun doesn't shine.

So what's your opinion on brain surgery? There has got to be more where the last one came from.

My initial post was a fishing post to try and provoke revelation for someone specific to respond. Didn't work. But atleast it brought out you from your ivory tower.

Finally: JPL intends to get a GRASP on accurate sea level and ice measurements

Posted on October 30, 2012by Anthony Watts

A climate science bombshell: New proposal from NASA JPL admits to “spurious” errors in current satellite based sea level and ice altimetry, calls for new space platform to fix the problem.

People send me stuff. Today it is a PowerPoint presentation from NASA JPL that touts the new GRASP (Geodetic Reference Antenna in Space) satellite project. I’d say it is more than a bit of a bombshell because the whole purpose of this new mission is to “fix” other mission data that apparently never had a stable enough reference for the measurements being made. This promises to rewrite what we know about sea level rise and acceleration, ice extent and ice volume loss measured from space.

TRF errors readily manifest as spurious sea level rise accelerations

That’s a bucket of cold water reality into the face of the current view of sea level rise. It puts this well-known and often cited graph on Sea Level Rise from the University of Colorado (and the rate of 3.1 mm/yr) into question:

What’s a TRF error? That stands for Terrestrial Reference Frame, which is basically saying that errors in determining the benchmark are messing up the survey.

Sea Level rises ...So many errors....so much bullstish

New paper finds global sea levels will rise only about 5 inches by 2100

A new peer-reviewed paper by sea level expert Dr. Nils-Axel Morner concludes that Australian government claims of a 1 meter sea level rise by 2100 are greatly exaggerated, finding instead that sea levels are rising around Australia and globally at a rate of only 1.5 mm/year. This would imply a sea level change of only 0.13 meters or 5 inches by 2100. Dr. Morner also finds no evidence of any acceleration in sea level rise around Australia or globally.

From the conclusion of the paper:

In view of the data presented, we believe that we are justified to draw the following conclusions:

(1) The official Australian claim [2,3] of a present sea level rise in the order of 5.4mm/year is significantly exaggerated (Figure 3).

(2) The mean sea level rise from Australian tide gauges as well as global tide gauge networks is to be found within the sector of rates ranging from 0.1 to 1.5 mm/year (yellow wedge in Figure 3).

(3) The claim of a recent acceleration in the rate of sea level rise [2,3,12] cannot be validated by tide gauge records, either in Australia or globally (Figure 3). Rather, it seems strongly contradicted [19,21,24,39-41]

The practical implication of our conclusions is that there, in fact, is no reason either to fear or to prepare for any disastrous sea level flooding in the near future.

the assumption is that global sea level rise with respect to time has a simple linear relationship

The positive feedback loops and ice dumping events will most certainly drive the sea level rise beyond linearity

The planet is stuffed!

And nothing will be done because the WEST is under a corporate fascist dictatorship regime.

Sea levels are not rising at the alarming rate Al Gore predicts.

Quote:

The uncompromising verdict of Dr Mörner is that all this talk about the sea rising is nothing but a colossal scare story, writes Christopher Booker.

Christopher Booker
6:25PM GMT 28 Mar 2009

If one thing more than any other is used to justify proposals that the world must spend tens of trillions of dollars on combating global warming, it is the belief that we face a disastrous rise in sea levels. The Antarctic and Greenland ice caps will melt, we are told, warming oceans will expand, and the result will be catastrophe.

Although the UN's Intergovernmental Panel on Climate Change (IPCC) only predicts a sea level rise of 59cm (17 inches) by 2100, Al Gore in his Oscar-winning film An Inconvenient Truth went much further, talking of 20 feet, and showing computer graphics of cities such as Shanghai and San Francisco half under water. We all know the graphic showing central London in similar plight. As for tiny island nations such as the Maldives and Tuvalu, as Prince Charles likes to tell us and the Archbishop of Canterbury was again parroting last week, they are due to vanish.

But if there is one scientist who knows more about sea levels than anyone else in the world it is the Swedish geologist and physicist Nils-Axel Mörner, formerly chairman of the INQUA International Commission on Sea Level Change. And the uncompromising verdict of Dr Mörner, who for 35 years has been using every known scientific method to study sea levels all over the globe, is that all this talk about the sea rising is nothing but a colossal scare story.

Despite fluctuations down as well as up, "the sea is not rising," he says. "It hasn't risen in 50 years." If there is any rise this century it will "not be more than 10cm (four inches), with an uncertainty of plus or minus 10cm". And quite apart from examining the hard evidence, he says, the elementary laws of physics (latent heat needed to melt ice) tell us that the apocalypse conjured up by
Al Gore and Co could not possibly come about.

Will post more on this when i can post web sites.

Who did the peer reviews, and which journal was it published in?

It would be hard to predict how some of this feedbacks loops will affect rates of melting. I doubt this is a model sophisticated enough to predict with much accuracy.

There are too many variables like how much extra energy will be absorbed due to less white ice reflecting the radiation fro the sun, and how much difference will more sean less land make in stabilising Arctic temperatures and providing warmer winters. How will extra humidity work in trapping heat in the atmosphere. How much radiation from the sun will be reflected due to extra cloud cover? All these things are unknown.

What we do know is that if the Greenland ice sheet alone melts it will raise sea levels by about 15 metres - most of Sydney gone!

I have a feeling that he's using tidal gauges instead of satellite altimeter data. The problem with tidal gauges is that the land itself is in motion. For example most of Scandinavia is still rising after the last Glacial period.

The Satellite altimeter data shows a steady rise, but as other posters point out, it's unlikely to continue on a linear trend. The main contributing factors are mean ocean temperature and the degree of melting of the Greenland Ice Sheet.

I understand that INQUA is distancing itself from Nils-Axel Morner's paper.
