Sea level rise: It's worse than we thought
New Scientist ^ | 01 July 2009 | Anil Ananthaswamy

Posted on 07/06/2009 10:32:33 PM PDT by Lorianne

In its 2007 report, the Intergovernmental Panel on Climate Change (IPCC) forecast a sea level rise of between 19 and 59 centimetres by 2100, but this excluded "future rapid dynamical changes in ice flow".

"Larger rises cannot be excluded but understanding of these effects is too limited to assess their likelihood," the IPCC report stated.

Even before it was released, the report was outdated. Researchers now know far more. And while we still don't understand the dynamics of ice sheets and glaciers well enough to make precise predictions, we are narrowing down the possibilities. The good news is that some of the scarier scenarios, such as a sudden collapse of the Greenland ice sheet, now appear less likely. The bad news is that there is a growing consensus that the IPCC estimates are wildly optimistic.

Even if all emissions stopped today, sea level would continue to rise. "The current rate of rise would continue for centuries if temperatures are constant, and that would add about 30 centimetres per century to global sea level,"

"If we burn all fossil fuels, we are likely to end up with many metres of sea level rise in the long run, very likely more than 10 metres in my view."

This might sound dramatic, but we know sea level has swung from 120 metres lower than today during ice ages to more than 70 metres higher during hot periods. There is no doubt at all that if the planet warms, the sea will rise. The key questions are, by how much and how soon?

WTH! In the article it clearly states that sea levels have been much higher and much lower that todaty in past periods of history ... yet they just nflinchingly carry on with the assumption that "burning fossil fuels" is causing warming at present.

Even if you concede that humans are affecting the climate in some way ... they have no clue by how much and no way to compare that to natural fluctuations in climate that have occured in the past and no way to confirm or deny that natural causes are working now either in conjunction with or human actions ... or dwarfing human actions.

The unknown variables are astounding ... even if you allow that anthropomorphic climate change is occuring.

Where do these people get the chutzpah and where can I get some of it!

we know sea level has swung from 120 metres lower than today during ice ages to more than 70 metres higher during hot periods

And we also have the issue of Teutonic plate movements that have gone on since the earth was formed, these have created mountains and sank continents - so how much of the sea level changes are accounted for by the Teutonic plate movements?

I think that fat people are not only harder to kidnap, they must also slow the Teutonic plate movements too - because we all know that man it to blame for everything, and nothing moves fast with fat people standing on it. I graciously present my 'FACT' with the same authority and scientific work that is presented by the Global Warming alarmists. (Yup, I made it all up - Where's my Nobel prize?)

CO2 does come from human activity, 3-5% of all CO2, the rest is natural. The real question is does it have any real effect on global temperature, and so far the evidence says no.

CO2 dramatically increased in the last 10 years as global temps have gone down, contrary to the IPCC models. There is no causation, so all the hysteria is misguided.

The evidence is clear. The debate is over. The science is settled. Cro-Magnon Man loved his 8 passenger Suburban. But, at least they had Geico.

OMG! Don't these people ever shut up? They cannot know; they are projecting. The sea levels are probably rising--change is what geological history is all about. Man burning fossil fuels AIN'T making it happen.

It's been a long time since geology class; but I remember there were glaciers-they melted-Texas and Oklahoma eventually were covered by tropical seas.Probably only took a few hundred thousand years.

In other words “We really don’t have any idea what is going to happen but if we told you that we wouldn’t get our government research grants.”

The good news: With a big enough rise in sea level, we could get rid of New Orleans, New York City, Washington, DC, parts of California and the East Coast, and large sections of Europe and Russia. And have warmer winters, too.

The bad news: The British Museum would have to be relocated to somewhere in the Scottish Highlands.

All in all, quite a bit more than a fair trade, I'd say.

. T.M.Gerlach (1991, American Geophysical Union) notes that human-made CO2 are dwarfed the estamated global release of CO2 from volcanoes by at least 150 times.

http://www.geology.sdsu.edu/how_volcanoes_work/climate_effects.html

US can contribute capn’trade taxes to the extent of 1/15 of what the rest of the world is to pay (if they do)...China and India are huge emitters. US alone will pay a huge price for nil result. Nothing rational here at all.

Total world output of manmade CO2 is irrelevant to global warming. Furthermore, since 2006 world temperature has dropped 0.76 of a degree.

These alarmist whackjobs just don’t give up, do they? In 1980, they asserted that Antarctica would melt by 2030, causing the seas to rise by 250 feet by 2030. Here it’s practically 2010, and the seas haven’t even risen half an inch in the last 30 years. The BS never ends from these shameless morons.

I must say I am not impressed by the brainpower of these New Scientists.

First we know that there have been extrememe fluctuations in sea level many times in the past without man and fossil fuels being part of the equation.
Now, suddenly, the burning of fossil fuels will "likely end up with many metres of sea level rise..."

HELLO??!!??

Might it not be more credible to document scientifically and persuasively what caused the dozens of rises and falls of sea level before fossil fuel use? Before going on hysterically with the absolute certainty that only the ignorant can possess?

Junk Science at its best.

The data is inconclusive yet it has been massaged to meet a political agenda.

It’s interesting that the recent slackening of sunspots has had an almost immediate affect on temperature averages.

Did anyne read the Rolling Stone article last week, where Al Gore and Goldman Sachs will make millions and millions from trading cap and trade??????

It’s all a sham.....and the media is in on it.

You are right to be concerned about the brain power of the global warming fanatics...

First, note, that much of the origin of the hysteria is based on the fiction that sea level has changed as dramatically as they say it has in the past. The archaeological evidence for sea level changes is real, but that doesn't mean you should ASSUME it is the water level that rises and falls, and not the level of the land itself. That degree of change in sea level as a function of changing ocean volumes is a fiction that predates our awareness of plate tectonics. The entire coast of Oregon is presently a couple of hundred feet higher than in the recent geological past... not because the water is lower ? Parts of western Oregon are still rising... surprisingly rapidly ?

Then, note, that if the sea level is going to rise as much as they say, all the water needed to make it rise has to come from somewhere ? Since ice that is floating at sea is already contributing all it can to higher sea levels... that means the only contributor to higher sea level can be ice melt from land. The ocean covers 70% of the planets surface. That leaves 30% land surface. Of that 30%, what portion is permanently covered with ice ??? How deep is the ice ? Or, how deep would the ice HAVE to be over what portion of the surface to have sufficient volume, after shrinking upon melting, to raise sea level as much as claimed ?

Do the math yourself... and you'll find it appears you can't get there from here. The reality is that if ALL the ice melted, sea level would rise perhaps as much as six inches... which is significantly less than the tidal variations over much of the planet... and it is far more likely that no one even would notice it than it is that we would see that event as a catastrophe worse than monthly highs in the tides.

Sea level rise: its worse than we thought?

Well obviously it is. In order to keep the dollars coming in the alarms have to get more and more hysterical.

By next year I expect sea levels will be predicted at over 100 metres. By 2012 maybe by 150 metres.

I did the math out of curiosity when they claimed 200’ in another article.

All the Oceans on the planet covers 360 million kilometers square.
I converted to English just to keep it in the 200’ perspective.
1 Square Mile = 2.5899.... square Kilometers.
The Water surface area of earth is 138,996,777 sq miles.
A 200’ rise = 5.57568 E9 ft^3/sq mile.
Multiply that times the surface area of the Oceans gives you 7.75 E18 ft^3.
Divide that number by 1.47197952 E11 (ft^3/mile^3) and you get 5.265 E11 mile^3
OR

52,650,000 cubic miles of water!

I would be willing to bet that there is not that much snow and ice on the entire planet.

It means the evil global-warming deniers have been monitoring your activities by tapping your phone and photographing you walking around central Florida. Thereby they know where you are going to dig your hole, and they sneak in the night before and bury seashells that they have aquired from Jacksonville beaches and crushed into fragments with a giant tractor (a 4x4 gas-guzzler at that).

It sounds incredible doesnt it? But it just shows the lengths to which these people will go to...

Ahh, Someone has rediscovered Teutonic Plate Movements! Yes, it's true - global warmism is a coverup of the impact of the German Dinner Table and it's Teutonic Plate Movements! Piled high with bratwurst and schnitzel, many places in Germany will make schnitzel large enough to cover the entire plate, so that the sides have to be placed on another plate next to it, thus increasing the impact of Teutonic Plate Movements! It's incredible AND edible at the same time!
