This is not a "smart" response to the factual data that sea levels have been rising for most of the last 25,000 years...so rising sea levels are nothing new. In fact, it's the typical scientifically ignorant "blockhead" response.

Get back to me when you figure out what kicked earth's climate out of the last Ice Age and started the 25,000 year warming trend.

Hint, it wasn't elevated concentrations of carbon dioxide..CO2 in earth's atmosphere.

So yes, on average the rise has been so many cms per year, but it didn't happen in a steady way but fits and starts.

And excess CO2 has been present in every warming period studied by our scientists. Was it msnmade? No, probably not before the Industrial revolution. Does that mean we can't do anything about it? Or that we shouldn't try?

u guys know about tides and land reclamations etc....the sea levels are always going up and always going down...on the one hand in antquity it could be that during the times Homer wrote the Iliad that the seas were much shallower than now given some of his descriptions ....on the other hand, i do think the deluge was a fact of life in some episode of Earth's history, and no doubt the water levels rose up then...on astrology forum, i have to say, it's water, it's always going up and down, we should start worrying if it ever got stable.

How about YOU get back to ME when you start quoting something verifiable?

Saying that sea levels have been rising for 25,000 years doesn't invalidate the scientific notion that sea levels have accelerated in their rising in modern times, does it? There's absolutely not even a smidgen of disproof of anything in saying that. Are you starting to feel smart?

Further, the melting of the ice ended 6000 years ago, and only recently started rising again:

Nineteenth and Twentieth Century Changes in Sea Level

Abstract

Following the Last Glacial Maximum (25,000–20,000 years ago), sea level rose at rates on the order of several tens of millimeters per year at times, and increased overall by over 130 m. However, melting of the great ice sheets was largely complete by 6,000 years ago, and it is believed that sea level did not rise significantly again until recently. The rates of sea level change during the last few centuries and in recent decades can be measured in units of millimeters per year and are particularly important in understanding present-day climate change. We now have a range of techniques with which sea level changes can be measured and thus studied more intensively than before, as a global average and in each region. This article introduces each of the main data sets and presents the primary research findings. It is hoped that a greater understanding of the reasons for past observed sea level change, discussed elsewhere in this issue, will lead to better estimation of the changes likely to occur in the future. http://www.tos.org/oceanography/archive/24-2_woodworth.html

Sea levels during several previous interglacials were about 3 to as much as 20 meters higher than current sea level. http://pubs.usgs.gov/fs/fs2-00/

No cause for concern, of course.

(From: Advancing the Science of Climate Change 2010, National Academies Press)
however, there is widespread consensus that substantial long-term sea level rise will continue for centuries to come (Overpeck and Weiss, 2009). A considerable amount of sea level rise is to be expected simply from past CO2 emissions as the ocean heat content catches up with radiative forcing (see Chapter 6); furthermore, the risk of ice sheet collapse, and the attendant large rates of sea level rise, will increase if GHG concentrations in the atmosphere continue to increase. http://books.nap.edu/openbook.php?record_id=12782&page=245

Description

Climate change is occurring, is caused largely by human activities, and poses significant risks for--and in many cases is already affecting--a broad range of human and natural systems. The compelling case for these conclusions is provided in Advancing the Science of Climate Change, part of a congressionally requested suite of studies known as America's Climate Choices. While noting that there is always more to learn and that the scientific process is never closed, the book shows that hypotheses about climate change are supported by multiple lines of evidence and have stood firm in the face of serious debate and careful evaluation of alternative explanations. http://books.nap.edu/catalog.php?record_id=12782

There's no such thing as "excess" CO2. We have the amount we are supposed to have at any given time as a byproduct of a lush green Earth.

Fair enough, bad word choice. Call it noticeably higher levels...the data remains the same.

I think "excess" is a fair way of talking about extra levels of CO2 that wouldn't otherwise be there.

I don't think you have. You even started this thread, not with article confirming "Sea Levels Are Falling," but rather that sea level rise is decelerating.

The Intergovernmental Panel on Climate Change stated in 2007, “Global average sea level rose at an average rate of 1.8 mm per year over 1961 to 2003. The rate was faster over 1993 to 2003: about 3.1 mm per year.” This translates to a 100-year rise of only 7 inches and 12 inches, far below the dire predictions of the climate alarmists.

But three millimeters is about the thickness of two dimes. Can scientists really measure a change in sea level over the course of a year, averaged across the world, which is two dimes thick?

Today, sea level is measured with satellite radar altimeters. Satellites bounce radar waves off the surface of the ocean to measure the distance. Scientific organizations, such as the Sea Level Research Group at the University of Colorado (CU), use the satellite data to estimate ocean rise. The CU team estimates current ocean rise at 3.2 millimeters per year.

The organizations AVISO (Archiving, Validation, and Interpretation of Satellite Oceanographic Data) of France, CSIRO (Commonwealth Scientific and Industrial Research Organization) of Australia, and NOAA (National Oceanic and Atmospheric Administration) of the United States agree with the University of Colorado that seas are rising three millimeters per year. Given the huge natural variation in global sea level, the three millimeter number is incredible. The fact that four different organizations have arrived at the same number is suspect.

As Dr. Willie Soon of Harvard shows, ocean level variation is large and affected by many factors. If temperatures rise, water expands, adding to sea level rise. If icecaps melt, levels rise, but if icecaps grow due to increased snowfall, levels fall. If ocean saltiness changes, the water volume will also change.

The land itself moves continuously. Some shorelines are rising and some are subsiding. The land around Hudson Bay in Canada is rising, freed of ice from the last ice age. In contrast, the area around New Orleans is sinking. Long-term movement of Earth’s tectonic plates also changes sea level.

Tides are a major source of ocean variation, primarily caused by the gravitational pull of the moon, the sun, and the rotation of the Earth. Ocean water “sloshes” from shore to shore, with tides changing as much as 38 feet per day at the Bay of Fundy in Nova Scotia. The global average tide range is about one meter, but this daily change is still 300 times the three-millimeter change that scientists claim to be able to measure over an entire year.

Storms and weather are major factors affecting satellite measurements. Wave heights change by meters each day, dwarfing the annual rise in ocean level. Winds also change the height of the sea. The easterly wind of a strong La Niña pushes seas at Singapore to a meter higher than in the eastern Pacific Ocean.

Yes, they all want to believe in sea level rise, but their measurements cannot prove it.

That's false. Where do you get that idea? I specifically remember looking at what these agencies take into account when doing their calculations, because that was the premise of your article --that they weren't accounting for this or that variable. Go to those links. They mention plenty of variables they take into consideration.

You're attempting the opposite: faith into empiricism. Understand yourself and what you think.

When you presume to "already clear something up for me," it should be noted that just because you post a graph from one of your alarmists, it doesn't clear up anything--much like when I post journal articles and statements from scientists who are specialists in their field that refute the man-made warming theory, but you dismiss.

Duh, I suspect you're dumb in whatever room you find yourself in acoustic. I see little hope you'll ever be able to pull your head out.

More evidence you're a scientific illiterate. Apparently you don't know the earth was locked in ice sheets that extended south into the plains of the United states during the last Ice Age. Let me ask you, where do you think all the water from that melting ice from all over the northern hemisphere went when the sun started emitting more energy and warming the earth about 25,000 years ago?

You are undoubtedly one of the most uninformed/misinformed members ever to post on this forum.
