quote: If you place an ice cube or two into a glass and fill it with water to the rim, the melting ice won't cause the water to overflow because it has already displaced the mass that it would take up if it were liquid.
quote: There are three estimates of sea level changes for Tuvalu. The first is a satellite record showing that the sea level has actually fallen four inches around Tuvalu since 1993 when the hundred-million dollar international TOPEX/POSEIDON satellite project record began. Second comes from the modern instruments recording tide gauge data since 1978. There the record for Tuvalu shows ups and downs of many inches over periods of years. For example, the strong El Nino of 1997-98 caused the sea level surrounding Tuvalu to drop just over one foot. The El Nino Southern Oscillation is a natural - as opposed to man-made -future of the Pacific Ocean, as areas of the Pacific periodically warm then cool every few years, causing significant sea level rises and falls every few years in step with the co-oscillations of the ocean and atmosphere. The overall trend discerned from the tide gauge data, according to Wolfgang Scherer, Director of Australia's National Tidal Facility, remains flat .

quote: While in the past we have used the tide gauge calibration values as direct corrections to the altimeter data, recent improvements in the sea state bias correction [Chambers et al., 2003] now make this unnecessary, as the curve is relatively flat . In summary, the altimetric results are considered to be extremely robust, and the estimate of sea level rise of 2.8 ± 0.4 mm/yr over the last decade is very reliable within these error bars.
quote: I don't know if Tuvalu is actually experiencing rising ocean levels or not
quote: I guess the people of Tuvalu must be imagining the rising sea levels.
quote: I'm merely reporting a story. Morner -- indisputably one of the world's top experts on sea level -- is the one expressing an opinion here.
quote:Data collected in this manner has shown the ocean to have risen and fallen slightly several times since the early 1900s, without any definitive trend.
quote: Is he correct? Form your own opinion. The purpose of good journalism is to report facts and let people judge for themselves.
quote: Another important result of satellite altimetry concerns the nonuniform geographical distribution of sea level change, with some regions exhibiting trends about 10 times the global mean. Thermal expansion appears responsible for the observed regional variability. For the past 50 years, sea level trends caused by change in ocean heat storage also show high regional variability. The latter observation has led to questions about whether the rate of 20th century sea level rise, based on poorly distributed historical tide gauges, is really representative of the true global mean. Such a possibility has been the object of an active debate, and the discussion is far from being closed.
quote: I then contacted two other scientists who, though neither had a view as strong as Morner's, both agreed that the IPCC was inflating the issue.

quote: The secular decrease of the Earth’s oblateness (as described by the J2 coefficient of the spherical harmonic expansion of the gravity field) observed by geodetic satellites during the past 25 years [Cox and Chao, 2002] is approximately -2.8x10^-11/yr (Figure 15).(3) The observed secular motion of the Earth’s rotation pole (true polar wander) is toward Canada [Dickman, 1979; McCarthy and Luzin, 1996]. These three observations have been generally explained by postglacial rebound [Johnston and Lambeck, 1999; Kaufmann and Lambeck, 2000; Peltier, 1998; Peltier and Jiang, 1996; Sabadini and Vermeersen, 2002; Vermeersen et al., 1997]. Indeed, viscous mantle material flowing from low latitudes toward high latitudes in response to the last deglaciation that started 18,000 years ago led to large-scale mass redistribution within the Earth system, hence causing a change of the Earth’s inertia tensor. Because the Earth is deformable, the rotation rate and rotation axis adjust themselves in order to conserve angular momentum. In the absence of other torques, changes in LOD are directly proportional to changes in the polar moment of inertia (C)
quote: Satellites calibrated to what standard though? The article points out that one of the accusations being made is that the IPCC changed all the old data by "calibrating" it with tide gauge data: and not just any tide gauge, but one that was in an area of known land level change.
quote: While in the past we have used the tide gauge calibration values as direct corrections to the altimeter data, recent improvements in the sea state bias correction [Chambers et al., 2003] now make this unnecessary, as the curve is relatively flat. In summary, the altimetric results are considered to be extremely robust, and the estimate of sea level rise of 2.8 ± 0.4 mm/yr over the last decade is very reliable within these error bars.
quote: Now, I don't know if these accusations are true, but they are the biggest accusations that can ever be made in the scientific world. Their implications are huge and they must be investigated; whoever is wrong, be it the accuser of IPCC, will be in very hot water indeed.
quote: Sea level changes can be detected by a number of methods. Rotational timing is a very precise method, and is based on the fact that a change in the earth's radius will cause minute differences in it's rate of rotation. A rise in sea level increases the radius slightly, and can therefore be detected by precisely timing when the sun rises and sets. This method can detect changes in sea level as small as one millimeter. Data collected in this manner has shown the ocean to have risen and fallen slightly several times since the early 1900s, without any definitive trend.
quote: The IPCC's altimetry dataset, which had previously displayed no clear trend, suddenly changed, with past readings modified to show a strong uplift. Though corrections to datasets are supposed to be clearly announced and identified, this was done secretly, and not labeled. When Mörner inquired about the discrepancy, he was told the readings had been adjusted by a "correction factor".

quote: Comparisons to tide gauge sea levels measured in spatial and temporal proximity to the satellite measurements suggest there is a residual drift in the satellite measurement system of -2.3 +/- 1.2 mm/year, the origin of which is presently unknown. Application of this rate correction yields a ³calibrated² estimate of +2.1 +/- 1.3 mm/year for the rate of sea level rise, which agrees statistically with tide gauge observations of sea level change over the last 50 years.

quote: #2 is nothing I've ever heard before. In fact, I challenge you to use that "meaning" of science in a sentence
quote: The OPs meaning was both clear and accurate. In some usages, "science" means the human search for knowledge. In others, it means that knowledge itself, independent of our search for it.
quote: Lol, so even when the dictionary itself proves you wrong, you still want to argue the point? Please don't be a buffoon.
quote: In some usages, "science" means the human search for knowledge. In others, it means that knowledge itself, independent of our search for it.

quote: Pretty sure doesn't work. You can look but Jesus never said he was God. Strange because God would have nothing to fear as God walking on the earth even in mans form.
quote: Christianity places Jesus before God as a way to get into heaven. Christians have broken "Thou shall worship no one before me". Thats a pretty big rule to break are you sure you want to go against God's word?
quote: I suggest not just taking what the church tells you is right and look into what the text actually says. Christians should stop protesting movies and video games and try cleaning up some of those TV evangelists who preach Jesus for their own personal wealth instead.
