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Even before it was released, the report was outdated.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?

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...

what the heck could that mean?

It means that sea shells were used for landfill.
The beaches in Florida use to be nothing but sea shells.

Salmon fishing from the top of the Empire State building. What’s not to like? Bring on the baked potatoes and salad.

Those damn Germans!

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!

If this was a real concern, liberals would be falling all over themselves trying to get dikes built around Washington.

Guess we’re not turning into Holland after all.

Here it’s practically 2010, and the seas haven’t even risen half an inch in the last 30 years.

You would think that sooner or later that people that report this stuff would take a minute to ask the source: "There has been a very slow and steady rise for several hundred years, that obvously isn't caused by cars and power plants. When will this dramatic rise caused by cars and power plants start?"

"There has been a very slow and steady rise for several hundred tens of thousands years,..."

About 40k IIRC. Just sayin'...

chainsaw: Geologists believe that the Cenozoic sea levels in Florida have fluctuated from several hundred feet or more above the present level to more than several hundred feet below present sea level. 60% of Florida is currently less than 75 feet in elevation.

This is what is known as the hardsell, as the time runs out and the client begins to get fidgety you have to up the ante and as what they are selling is fear that means they have to make it more fearful.

In this case, these desperate warnings will continue and accelerate as we move toward the rundown of the funding clock which is set to occur in December in Copenhagen at the world summit.

BTW, all this sea level business is wild speculation and is based mainly on highly questionable ‘smoothing’ of existing data — no new work is presented here.

It will only get worse as we get closer.

Yeah, “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.”” they weren’t satisfied with predicting the climate 100 years out so they moved out to 350 years — neat tactic, 15 generations.

The only unequivocal evidence of a "problem" is the steady increase in measured CO2 levels since 1954, all the rest is based on models and corrected observational temperature data.

1024 arrived day before yesterday and remains visible; quite pronounced and definitely of a cycle 24 type.

Makes the 17th spot this year.

Canadian professor Tim Ball just wrote a stunning refutation of the sea-is-rising doomists. It appeared on the CFP (Canadian Free Press) website yesterday. I printed it out, and am now staring at it.
