Sea level rise linking to global warming

[Oddball]

Blaming this on CO2 is complete crap. Sea level rise along the East coast has been fixed for 100 years. In New England there is little to no sea level rise over the last 40 years. Sea level on the US Pacific Coast is not rising at all.

If CO2 was the cause, we would have expected to see a sharp rise after 1950, when atmospheric CO2 began to rise quickly. By contrast, sea level rise rates along the Atlantic coast have slowed since 1950.

So you are saying Westwall is lying?

This sea level rise problem I only look at with passing interest. Just funny everyone has different stats and claims the other side is faking it. Wonder who has money to make.

It ain't our fault Mr. Bond. Americans didn't do it so stop wasting your time trying to convince Americans to willingly become part of Obama's 3rd world apology network.

No, they are not stating that at all. Mann and company are lying however. Isostatic rebound is well known and described in geologic journals. The claim that .3mm must be added to make up for the "expansion" of the ocean basins is spurious however. There is NO evidence to support that particular bit of "information".

 

[IanC]

is it just me, or does anyone else find it odd that tide gauges for the last 100+ years have shown a rise of <2mm/yr and satellite altimetry has shown a rise of ~3mm/yr but no one talks about the discrepancy. must be all those bulges out in the oceans where we just have to take someone's word for it.

funny how the best measured and most measured places in the world always read low but the places that have scant measurements are always going off chart and raising global averages. jus' sayin'

 

[IanC]

speaking of things that dont make sense. global temps can be broken down into tropical, northern hemisphere and southern hemisphere. the tropical band has changed very little. the SH has warmed about 1/2 of the NH. the continental US is the best and most measured area in the world and its temps are lower than the trend for the NH or even the global trend. so where is all that warming taking place?

ask Hansen about his 1200km arctic cells.

Church and White 2011 reports tide gauges showing sea level rise of 2.8mm +- 0.8mm for the period 1993-2009.

A consistent link exists between changes in global mean surface temperature and sea level, resulting in a greater rate of sea-level rise along the U.S. Atlantic coast than that of the past 2,000 years, says an international research team.

“Sea-level rise is a potentially disastrous outcome of climate change, as rising temperatures melt land-based iced and warm ocean waters,” says Benjamin Horton, associate professor and director of the Sea Level Research Laboratory at the University of Pennsylvania.

Horton and Andrew Kemp, fellow postdoctoral now at Yale University’s Climate and Energy Institute conducted the research which was published in the journal Proceedings of the National Academy of Sciences on June 20.

The team constructed a new 2,000-year history of seal level elevations, which will help scientists refine the models currently used to predict climate-change-induced sea level rise.

By combining the sea level changes through time with the already established temperature record for the past 1,000 years, researchers were able to create a model that is partly based on observations, and matches what occurred historically. Future changes in sea level can therefore be predicted.

Results from the study showed that sea level was relatively stable from 200 B.C. to 1,000 A.D.

Sea level rose by almost half a millimeter a year for 400 years starting in the 11th century, known as the Medieval Climate Anomaly, when the climate started to warm, say researchers.

Then a second period of stable sea level associated with a cooler period known as the Little Ice Age occurred and lasted until the late 19th Century.

The study says that since the 19th Century, sea level has risen by more than 2 millimeters per year on average, which is considered the steepest rate for more than 2,100 years.

I'm still confused as to how the sea level can continue to rise while the shoreline stays in the same place.

I'm also a little confused as to how the sea level can stabalize during the Little ice Age times despite the fact that the Greenland glacier was expanding along with the glaciers on most mountains around the world.

Does the sea level rise during warm periods and not drop during cold periods? Where is the extra water coming from that adds to glaciers without taking away from the sea level? Who proof reads this stuff? Is anybody doing a rantionality scan of this BS before they hit the "submit" button?

It did fall slightly. They do say relatively stable.

 

[IanC]

they claim a stable subsidence rate. read the article at Real Climate

It fell a shit load. Enough to add about 100 miles to the eastern states out into the Atlantic and the land bridge from Russia to Alaska.


"At this peak of the last glaciation, the sea levels were about 120-135 meters below their present level. Leading up to the peak in ice volume, sea levels would drop ~50 meters each millennium (or 2.5 inches each year)."

Here's some new peer reviewed scientific research on the rising sea levels that has just been published. Sea levels are rising faster now due to AGW than they have anytime in at least the last two thousand years, and probably much longer.

Sea-level rise in two millennia
June 23, 2011
(excerpts)

Showing a consistent link between changes in global mean surface temperature and sea level, the rate of sea level rise along the U.S. Atlantic coast is greater now than at any time in the past 2,000 years.

That conclusion comes from research conducted by Andrew Kemp of Yale University and others from various institutions.

The findings are published in the journal Proceedings of the National Academy of Sciences (PNAS).

Sea-level stable

The team found that sea level was relatively stable from 200 BC to 1,000 AD.

Then in the 11th century, sea level rose by about half a millimetre each year for 400 years, linked with a warm climate period known as the Medieval Climate Anomaly.

Then there was a second period of stable sea level during a cooler period called the Little Ice Age. It persisted until the late 19th century.

Since the late 19th century, sea level has risen by more than 2 millimetres per year on average, the steepest rate for more than 2,100 years.

We seem to have a whole bunch of pretty specific shorlines on the East Coast. New York, Boston, DC, St Augustine, Miami.

Please list those land marks that were on the shore in 1880 and are now under water.

Your case would be more believable if you could please produce some real world proof.

from Willis' latest article at WUWT. sea level rise is pretty variable. so you can push the numbers around by playing with the start/stop dates.

the journals only worry about data, methods and rationality if it is a paper that doesnt fall into lockstep with AGW. otherwise it is a free pass to dream up anything you want.
