[quote]IPCC Climate Change: The Bogus Claims of Catastrophic Sea Level Rise, Pacific Ocean Edition
Bogus claims of catastrophic disasters dominate the IPCC climate change reports - extreme exaggerations of sea level rise affecting Pacific islands is common but without any scientific merit
Read here. The United Nation’s IPCC has been extremely open about their perversion of climate science and how the political agenda rules the roost (the UN’s Rio conference being the next). A key means to manipulate the world’s policymakers and the public is to wildly exaggerate potential catastrophic disasters inferring a high likelihood. A favorite IPCC “disaster” is the rising seas caused by human CO2 emissions. A rise so high that will consume low-lying tropical islands and their cultures. But does that “looming” disaster have real merit?
Nope. Coastal tide gauges from around the world, documented in study after study, show that the current sea level rise is very modest and might reach a measly 3 to 7 inches by 2100.
But what about the vulnerable natives of Pacific island atolls? A recent peer reviewed article describes the situation of Tarawa of the Gilbert Islands.
“These common images of flooded homes and waves crashing across the causeways—collected during an anomalous event on islets susceptible to flooding due in part to local modifications to the environment—can provide the false impression that Tarawa is subject to constant flooding because of sea level rise…Many individual observations of erosion, flooding, or groundwater salinization, recorded in community consultations for internationally funded climate change adaptation programs, are thus attributed to climate change without scientific analysis…These events are presented as examples of climate change impacts in promotional materials and at international events…The failure to consider the contribution of natural variability and direct human modifications can lead to misattribution of flooding events or shoreline changes to sea level rise…Instead of incorrectly attributing individual flood events or shoreline changes to global sea level rise, scientists and climate communicators can use such occurrences to educate the public about the various natural and human processes that affect sea level, the shoreline, and the shape of islands.”
Conclusion: The IPCC climate change reports include wild exaggerations about potential climate disasters. There is no empirical evidence supporting these looming disasters from human CO2 emissions. The United Nations promulgates these non-scientific claims as fact at UN-sponsored conferences in order to promote their wealth redistribution political agenda. A classic example of this misrepresentation is the fraud that Pacific islands will be swamped by an extraordinary sea level rise, exclusively from human CO2 emissions.

[quote]Global Sea Level Rise: Melting Glaciers Have Tiny Impact On Sea Levels - Maybe 3.7 Inches By 2100
Alarmists have long predicted that Greenland’s melting glaciers were causing an “accelerating” global sea level rise - new study confirms global warming alarmists wrong

Read here. The predicted “accelerating” sea level rise has been a fearmongering staple of the IPCC’s global warming alarmists and the mainstream press for decades. For pure hysteria sake, nothing beats the image of flooding populous coastal areas with the intent to frighten the public. Unfortunately for the alarmists, the empirical evidence does not support their grossly speculative predictions from discredited climate models. Firstly, the “accelerating” global sea level rise has not taken place as multiple research studies have documented. Secondly, the alarmist creed that the melting of Greenland’s glaciers would cause devastating ocean rises has been completely debunked by a new peer reviewed study on some 200+ glaciers on the world’s largest island.
“…titled “21st Century Evolution of Greenland Outlet Glacier Velocities” [Moon et al.] examined the flow characteristics from nearly 200 glaciers across Greenland for the period 2000-2010 as analyzed using synthetic aperture radar data collected from various satellites…And what they found…was that the patterns of flow rate changes across Greenland were complex, both in space and time. Glaciers that were accelerating during a few years were found to be decelerating in others. Some accelerating glaciers were found in close proximity to other glaciers that were decelerating…“Finally, our observations have implications for recent work on sea level rise…Our wide sampling of actual 2000 to 2010 changes shows that glacier acceleration across the ice sheet remains far below these estimates, suggesting that sea level rise associated with Greenland glacier dynamics remains well below the low-end scenario (9.3 cm [3.7 inches] by 2100) at present…Our result is consistent with findings from recent numerical flow models.”” [Twila Moon, Ian Joughin, Ben Smith, Ian Howat 2012: Science]
Conclusion: Accelerating global sea level rise from melting glaciers is not happening as predicted. The retreat of Greenland’s glaciers is not a major contributor to sea level increases and there exists no empirical evidence that this will change by year 2100.

Tide Gauge Station Data Analysis: NZ Scientists Confirm Sea Level Rise Is Modest - 7 Inches By 2100
An expert tide gauge station analysis out of New Zeland confirms the obvious - current global sea level rise is barely noticable, which is complete contradiction of IPCC predictions over past 2 decades
(image source)
Read here. New empirical evidence from New Zealand scientists document the lack of “accelerating” global sea level levels. The island nation in the southern Pacific has not been swamped by the rising seas and the confirmed trend indicates only a 7 inch rise by 2100. The New Zealand documented trend is similar to those established by other research done by sea level experts. “With respect to the South Pacific Ocean, the authors indicate that there are few reliable tide gauge records with data predating 1950…In an attempt to improve this data-sparse situation, Hannah and Bell say that “an investigation was undertaken to determine whether historical data from other tide gauge sites could provide additional spatial coverage of relative sea level trends around New Zealand.”…the two New Zealand scientists report that “the average relative sea level rise calculated from the six newly derived trends was 1.7 ± 0.1 mm/year,” a result that they say “is completely consistent with the far more rigorous and conventional analyses previously undertaken for the four main ports using long-term tide gauge records.” And they write that “in a global context, this average trend in relative sea level rise is also consistent with the results of Church and White (2011), who find a global average linear trend in secular sea level rise of 1.7 ± 0.2 mm/year from 1900-2009.”” [Jonh Hannah, Robert Bell 2012: Journal of Geophysical Research, Oceans]
Conclusion: Tide gauge station analysis confirms global sea level rise is modest and not dangerously accelerating as long predicted by the IPCC’s climate models and its “experts.”
