There's an article in this week's Time(the Coulter issue!) which rather neatly sums up the GW movement.
Title:Where the Waters Are Rising
subtitle: A close-up look at the low-lying Maldives, where global warming hits the seawall.
Predictably, the article presents all sorts of doom and gloom scenarios for the Maldives(which sit 1-2 yards above sea level); it's inevitable, the article suggests, that the Maldives will be swallowed up by the ocean, due to global warming.
What they fail to mention, of course, is that the sea level is not actually rising there! In theory, hypothetically, it's possible, conceivable that the sea level could rise there.

Where's your evidence to support that it's not? I've certainly read a number of article stating it is, but never seen that it's not. Help me out.

And a good job at that. National Geographic, that hippy liberal non-sensical rag had an article in the last couple years about the trouble in the Maldives, Vanuatu, etc.

That is a website which simply cuts and pastes some of a published article. Without reading the whole thing, you simply can't be confident of what is being reported because who knows what they may have cut out? So, I took the liberty of getting the actual article they used. I can't post because you need to have access to Science Direct's database, but I'm willing to email anyone a copy. Or, you could look it up yourself.

While you are there, please check out this article, which essentially refutes what is said in the previous one anyway:

Hopefully no one will mind if I post that article here in full?

(2004) raise a number of important issues concerning sea level change and island morphological adjustment in the Maldives. These issues have great relevance for atoll nations as they shed light on the potential stability of reef islands with respect to future sea level change. Given the high international profile of reef island vulnerability it is important that the data and conclusions of such studies are robustly examined. In their article Mo¨rner et al. (2004) contend that sea level has undergone a recent fall in the Maldives and imply that reef islands there are not likely to be inundated if sea-level were to rise as predicted by the IPCC (Church and Gregory, 2001). Here we raise a number of concerns with arguments and data presented by Mo¨rner et al. (2004) that are central to the interpretations and conclusions presented in their paper. This discussion addresses: (1) the Last Interglacial and Holocene development of the Maldives; (2) the sea-level curve presented; and (3) evidence introduced to substantiate claims of recent sea-level fall. (1) The introduction of Mo¨ rner et al. (2004) contains a number of unqualified and unreferenced assertions that necessitate comment. First, they state the surficial reefs of the Maldives were not dominated by catch-up reef growth in the mid to late Holocene but are of pre-Holocene age. Second, they report reef rocks of Last Interglacial age occurring close to and below sea level and up to +1.2–1.3 m. No evidence is given in support of either claim and both are contrary to published data on reef development in the Maldives. For instance, Risk and Sluka (2000) note that Holocene reef growth began about 6000 years ago and continued in catch-up mode at 3 to 10 mm/ year (for the ensuing 3000 years) resulting in a total Holocene section of between 15 and 20 m. On Male, Woodroffe (1993) describes a Holocene reef sequence up to 17 m thick overlying the Last Interglacial reef. This evidence is in accordance with Purdy and Bertram’s (1993) as well as Bianchi et al.’s (1997) interpretation that the contemporary Holocene reef 0921-8181/$ - see front matter D 2005 Elsevier B.V.

(2) Mo¨rner et al. (2004, Fig. 1) present a new sealevel curve for the Maldives that encompasses the last 5000 years. This plot is potentially globally significant as detailed reconstructions of sea level history from this region are lacking. This curve is based on 12 data points derived from two sources. Seven of the dates are from Woodroffe (1993) who reports these samples as bulk sands, boulder conglomerates and only one in situ coral. This coral is a Heliopora with elevation with respect to present MSL of 0.0F0.3 m (2710F85 year BP). In our opinion this is the only reliable date from the Woodroffe (1993) dataset that could be used for sea level reconstruction. The remaining six samples are unreliable indicators of MSL and should not be included in Fig. 1. Five new dates are plotted by Mo¨rner et al. (2004, Fig. 1) as evidence of past sea level positions. However, no information is provided on what materials were dated (in situ coral or unconsolidated sediments) or how their relationship to current sea level was established. Furthermore, conventions for reporting C-14 ages are not followed. Standard information is missing, notably the actual dates, error terms, lab codes and calibration details (if any). In the one exception, we are perplexed why human remains (reef woman) should be subject to a dsea correctionT of some 400 years when the ocean reservoir correction should be used for marine specimens only (e.g. Reimer and Reimer, 2000). Of particular concern is the assertion that there have been higher sea levels at 4000 and 800 years when the latter is based on a boulder conglomerate and evidence for the former is not reported. Moreover, Bianchi et al. (1997) state that relative sea level stands higher than present are not known from Felidu Atoll which is mid way between the islands investigated by Mo¨rner et al. (2004). In our view, Fig. 1 should be disregarded as an accurate representation of the Maldives sea level history. (3) Mo¨rner et al. (2004) claim that their observational data sheds new light on the present to subrecent sea level changes as expressed in Fig. 3. For instance, in Fig. 3A, it is claimed that a sub recent level of 1.2 m above MSL on Hulhudhoo Island indicates a higher sea level of +0.3 m. Our evidence from repeat surveys of seven profiles on Hulhudhoo in 2002 and 2003 demonstrate that the sub recent level falls within the dynamic range of the contemporary erosion and accretion zone. Therefore we reject the notion that the sub recent level represents a sea level +0.3 m higher than present. Our evidence also suggests that the 1.45-m island surface level also falls within this level of contemporary morphodynamic change and does not represent a +0.6 m higher sea level. Beach rock positioned at 0.4–0.5 m above MSL is also used by Mo¨rner et al. (2004) to infer sea level change. Using beach rock as a palaeo sea-level indicator has been widely discussed and used in a number of studies (e.g. Scoffin, 1977; Scoffin and McLean, 1978; Hopley, 1982). These studies show that contemporary beach rock can form well above mean sea level and as identified by Hopley (1982) can exceed mean high water spring tide level by several centimeters. For the Maldives, beach rock at +0.4–0.5 m places it in the intertidal range. Our data from 12 traverses surveyed across contemporary beach rock exposures on Goidhoo atoll in 1995/1996 show an elevation range of 1.2 m from 0.4 to +0.8 m above MSL. Consequently, the elevations of beach rock reported by Mo¨rner et al. (2004) lie within the range of contemporary beach rock and cannot be used as an indicator of a higher sea level. In summary, we reject both the beach rock and morphological evidence for a significant sea level fall over the past 30 years. We conclude that the sea level history and data presented by Mo¨ rner et al. (2004) is less than compelling and can be readily explained via an understanding of contemporary coastal processes. The region’s sea level history remains uncertain. Consequently, we believe that this work does little to inform the international community on new perspectives of the future of the Maldives.

Wow, a list of people's names. People who were members of a commission on sea level changes and coastal evolution! I'm not sure if simply posting a link to that was somehow proof that global warming isn't happening, but if it was and I, in my stupidity, missed it, would you care to explain?

So the first mark, made in 1841 so we'd better trust it's validity, was an average.
The photo was taken at low tide.
Those two things don't seem to correllate to me.
Even if they did, one photo which lets face it, could be of anything, is not sufficient evidence for sea level change. Nor is that enough to suggest that global warming is a myth.

No, its much more amazing that EVERY topic will eventually become politicized. Tocqueville said that there is seldom an ideological question which does not eventually become a legal one, and there you go.

Ross' benchmark is quite famous and has been compared against current sea level readings several times in history.
But actually you do make a good point there.
In 1900, msl was 34 centimeters below the benchmark, in 2000 msl was 31 centimeters below it. Some would suggest that this would indicate a sea level rise of 3 centimeters over the course of the century, which is of course, meaningless. (these numbers really look silly when you consider sea level has risen some 120 meters since the last ice age).
GW advocates will tell you that there are many factors which can explain the paltry 3 cm rise.
My point would be that it's probably not possible to gauge sea levels without accurate readings spanning hundreds of years--for every advocate on one side, you'll find one who makes a convincing case for the other.
And of course, it's been generally held in science (long before the GW scare) that sea levels would be currently rising, as we are leaving a long glacial period.

Doesn't really change the fact that the amount of CO2 in the atmosphere has risen to 380ppm in the last 150 years when it had been between 200 & 300ppm for the last million years though, does it? And in that same period of time, the human population has risen from 1.5 billion to 6 billion and have been consuming fossil fuels at an exponential rate?
You don't have to base evidence global warming on sea level rise.

The earth has been around for billions of years. Certainly the dinosaurs didn't burn fossil fuel, and they were wiped out because of climate change. (The current theory.) I'm sure when the world was new, if there was life, they would be arguing about how to save the volcanoes, and molten lava fields.
If earth is ever changing.
Unless, of course, you believe that it was created six thousand years ago, and looks pretty much the same today as it did then.
I used to think Global Warming was beyond reproach, until I read State Of Fear, by Michael Crichton.
Of course he could be under the influence of someone's money, but isn't every organization at some point?
We need to look at this beyond our lives, at the past. Things won't stop changing just because we like the way they are, so....

This reminds me of George Carlin. He was going off on environmentalists who say "Save the Earth", and he was like, "The Earth will be fine, save your ASS!"
I'm not all that interested if the Earth can heal the damage we do over the next million years or two if we are able to make the planet uninhabitable by humans and the other creatures we love over the next couple hundred years. I'm a humanitarian, the Earth doesn't need my help.

Researchers: Data validates global warming projections World's rising sea temperatures a 'smoking gun'
Thursday, April 28, 2005 Posted: 2204 GMT (0604 HKT)
NEW YORK (AP) -- Climate scientists, with the aid of diving robots probing the world's warming seas, have found the heat exchange between Earth and space is seriously out of balance -- what the researchers called a "smoking gun" discovery that validates forecasts of global warming.
They said the findings confirm that computer models of climate change are on target and that global temperatures will rise 1 degree Fahrenheit (0.56 degree Celsius) this century, even if greenhouse gases are capped tomorrow.
If carbon dioxide and other heat-trapping emissions instead continue to grow, as expected, things could spin "out of our control," especially as ocean levels rise from melting Greenland and Antarctic ice sheets, the NASA-led scientists said.
The study, published Thursday in the journal Science, is the latest to report growing certainty about global-warming projections. A leading European climate scientist called it useful supporting evidence.
More than 1,800 technology-packed floats, deployed in oceans worldwide beginning in 2000, are regularly diving as much as a mile undersea to take temperature and other readings. Their precise measurements are supplemented by better satellite gauging of ocean levels, which rise both from meltwater and as the sea warms and expands.
Researchers led by NASA's James Hansen used the improved data to calculate the oceans' heat content and the global "energy imbalance." They found that for every square meter of surface area, the planet is absorbing almost one watt more of the sun's energy than it is radiating back to space as heat -- a historically large imbalance. Such absorbed energy will steadily warm the atmosphere.
The 0.85-watt figure corresponds well with the energy imbalance predicted by the researchers' modeling of climate change through a supercomputer, the report said.
Computer models, numerical simulations of climate change, factor in many influences on climate, including greenhouse emissions -- carbon dioxide, methane and other gases. Such gases, produced by everything from automobiles to pig farms, trap heat as they accumulate in the atmosphere.
Significantly, those emissions have increased at a rate consistent with the detected energy imbalance, the researchers said.
"There can no longer be genuine doubt that human-made gases are the dominant cause of observed warming," said Hansen, director of NASA's Goddard Institute for Space Studies at Columbia University's Earth Institute. "This energy imbalance is the 'smoking gun' that we have been looking for."
Fourteen other specialists from NASA, Columbia and the Department of Energy co-authored the study.
Scientists have found other possible "smoking guns" on global warming in recent years, but Klaus Hasselmann, a leading German climatologist, praised the Hansen report for its innovative work on energy imbalance. "This is valuable additional supporting evidence" of manmade climate change, he told The Associated Press.
In February, scientists at San Diego's Scripps Institution of Oceanography said their research -- not yet published -- also showed a close correlation between climate models and the observed temperatures of oceans, further defusing skeptics' past criticism of uncertainties in modeling.
Average atmospheric temperatures rose about 1 degree Fahrenheit (0.56 degrees Celsius) in the 20th century, and the Intergovernmental Panel on Climate Change, a U.N.-organized network of scientists, says computer modeling shows they will rise between 2.5 degrees and 10.4 degrees Fahrenheit (1.4 degrees and 5.8 degrees Celsius) by the year 2100, depending on how well emissions are controlled.
The Science study said the excess energy stored in the oceans means a 1-degree Fahrenheit (0.56 degrees Celsius) rise in atmospheric temperatures is already "in the pipeline." This agrees with findings of U.S. government climate modelers reported last month.
Besides raising ocean levels, global warming is expected to intensify storms, spread disease to new areas, and shift climate zones hundreds of miles, possibly making farmlands drier and deserts wetter.
