The ocean floor is likely sinking due to climate change, rendering sea level rise measurements over the last 20 years grossly inaccurate, Dutch scientists claim. Researchers from the Delft University of Technology say the sea has risen four percent higher than previously estimated over the past two decades. They published their findings in the journal Geophysical Research Letters late last month.
That may sound insignificant, but when coupled with the knowledge that the sea has risen by Sea level rise is primarily measured by satellites and GPS-corrected tide gauges, but such tools fail to account for a slumping ocean floor, the study contends, thereby accounting for the four-percent discrepancy between global sea level estimates and reality.
Now that the measurement error has been identified, it should be "relatively easy to account for" in future sea level models, lead study author Thomas Frederikse writes.

He points out that his formula confirms the theory of Isostatic Rebound and possibly paves the way for the acceptance of Earth Expansion as a plausible alternative. He goes on to explain that the formula proves the rate of Isostatic Rebound and by so doing supports the earth expansion theory.
How is this possible? He argues that if the Mueller formula proves the rate of Isostatic Rebound and Isostatic Rebound, as a theory, does not exist then it must be that the earth is expanding.
The Professor stresses that Post Glacial rebound is based on the original premise that the land mass arose from the sea. That original Darwinian premise was wrong, according to Guy. The opposite is true.Servicenow rest api limit
The land is not rising, it is the sea level that has been falling away from the land as the earth expands. Guy cites examples of the seas recession over time.

Humans are not going to stop sea level rise on the time scale of a few centuries by ceasing emissions of CO 2. August 14, And amid great physical-science uncertainty where subtle assumptions can drive the result, particularly in a politicized environment like with climate change, the ends should not justify the means.
Her transformation to climate optimism, relatively speaking, has produced a middle view of the climate debate that can be summarized in four major points:.
Human-caused sea level rise has been implicated in the destruction wrought by Hurricane Harvey in a variety of post mortems. In the hours before and after the eclipse, extra-high tides will occur as a result of the alignment between the sun, Earth, and moon.
Those enhanced tides will give us a glimpse of how sea-level rise will affect us — and we want your help to document those tides. Twelve pages follow pp. Yes, sea level is rising, but such is also the natural state of things coming out of the Little Ice Age that ended in the mid th century:.
Sea level has been rising since the last ice age, with some ups and downs. Sea level has been rising for the past years. Always meticulous, Curry refers to previous posts at her site Climate Etc. The good news is that sea level rise is much more modest than false prognosticators have led us to believe.
Rather than attempt to shave fractions of an inch off of future sea level rise in the distant future, policymakers should keep fossil fuels affordable, plentiful, and reliable to deal with climate and weather events of all kinds.
Judith Curry. Scary Sea Level Rise? Bradley, Jr. Her transformation to climate optimism, relatively speaking, has produced a middle view of the climate debate that can be summarized in four major points: Climate is changing and has an anthropogenic man-made component, with the enhanced greenhouse effect other things equal resulting in a warmer, wetter world with higher sea level.
The human influence is modest, not pronounced, with climate models overpredicting warming. Carbon dioxide emissions and rising atmospheric CO 2 concentrations have ecological and economic benefits, not only costs. Government mitigation policies will have negligible impacts on climate. Sea Level Fright Human-caused sea level rise has been implicated in the destruction wrought by Hurricane Harvey in a variety of post mortems.

It would take an average rate of sea level rise nearly twice that of the Holocene Transgression for sea level to rise more than 1. Sea level was meters higher than it currently is during the Holocene Highstand.
All of the sea level rise since is insignificant relative to the natural variability of Holocene sea levels. The mean sea level trend is 2.
The mean sea level trend is 3. The satellite data indicate virtually no statistically significant sea level rise in the Miami area:. This would lead to about 5.
This one on latitude -vs- concentration would surely seem to point to anthropogenic sources of CH This is the first increase in ten years, and what baffles science is that this data contradicts theories stating man is the primary source of increase for this greenhouse gas.
It takes about one full year for gases generated in the highly industrial northern hemisphere to cycle through and reach the southern hemisphere. Methane accounts for roughly one-fifth of greenhouse gases in the atmosphere, though its effect is 25x greater than that of carbon dioxide. Methane is typically broken down in the atmosphere by the free radical hydroxyl OHa naturally occuring process. The key thing is to better determine the relative roles of increased methane emission versus [an increase] in the rate of removal.
Apparently we have a mix of the two, but we want to know how much of each [is responsible for the overall increase]. The primary concern now is that is long over. While the collected data from that time period reflects a simultaneous world-wide increase in emissions, observing atmospheric trends now is like observing the healthy horse running through the paddock a year after it overcame some mystery illness.
Where does one even begin?
Study: We've measured sea level rise wrong for 20 years – and it's higher than previously thought
And how relevant are any of the data findings at this late date? Looking back over data as it was captured may prove as ineffective if the data does not support the high resolution details such a study requires. One thing does seem very clear, however; science is only beginning to get a handle on the big picture of global warming. Miami Beach topographic maps for and The North Atlantic hurricane season has nearly come to an end.
As November progresses, the chance of another storm developing becomes smaller. Climatology last 60 years tells us that roughly 4 in 10 years see a November storm formation including 4 in Beta, Gamma, Delta, EpsilonHurricane MichelleHurricane Lennyand Hurricane Kate Jeff Masters from the Weather Underground has an image of previous early-November storm tracks especially clustered in the Western Caribbean.
So, what has the season wrought in the North Atlantic and how well did the seasonal prognosticators fare? Even with the expected post-season tinkering of the real-time storm tracks by the folks at the National Hurricane Center, we can provide fairly accurate preliminary numbers.One of the scariest scenarios for near-term, disastrous sea-level rise may be off the table for now, according to a new study previewed at a recent scientific conference. Two years ago, the glaciologists Robert DeConto and David Pollard rocked their field with a paper arguing that several massive glaciers in Antarctica were much more unstable than previously thought.Lambda spice model
Such a rise could destroy the homes of more than million people worldwide. They are now revisiting those results. In new work, conducted with three other prominent glaciologists, DeConto and Pollard have lowered some of their worst-case projections for the 21st century. Antarctica may only contribute about a foot of sea-level rise bythey now say. This finding, reached after the team improved their own ice model, is much closer to projections made by other glaciologists.
It is a reassuring constraint placed on one of the most alarming scientific hypotheses advanced this decade. Yet their work—and the work of other sea-level-rise scientists—still warns of potential catastrophe for our children and grandchildren. If every country meets its current commitment under the Paris Agreement, the Earth will warm about 2. Read: A radical new scheme to prevent catastrophic sea-level rise.
Their new research also raises the marginal risk of disaster. Officially, the Paris Agreement aims to keep global warming from exceeding 2 degrees Celsius, though many experts consider that goal fanciful.
And even in that extremely optimistic scenario, West Antarctica still switches into unavoidable collapse about 10 percent of the time, according to the new research. Their short-term revisions also barely change their long-term forecast of West Antarctic disintegration.Neil deGrasse Tyson scolds cherry picking climate science
If emissions keep rising, they warn that global sea level could rise by more than 26 feet by These new results have not yet been peer-reviewed. DeConto, a professor at the University of Massachusetts at Amherst, presented them to other scientists last month at the fall meeting of the American Geophysical Union, the largest annual conference of Earth scientists in the world.
He and his colleagues declined to comment for this story in keeping with an academic custom not to discuss new work with the press before its publication. The new results inform one of the biggest outstanding questions—and most fervent debates—concerning how climate change will reshape our world: How much will the seas rise, and how fast will that upheaval occur? DeConto and several other American glaciologists—including Richard Alleya professor at Penn State and a co-author of the new research—represent something like the vanguard of that discussion.NASA shows 3.
The first thing they did was to add in a 0. This is a completely fraudulent adjustment based on theoretical sea floor sinking — which should be used to calculate the sea floor heightnot the sea surface height. Mind-blowing malfeasance. The next fraud was bait and switch. Untilthey use tide gauges, but after they switched to satellites. This change in instrumentation to uncalibrated satellites produced an immediate doubling of sea level rise rates. Tide gauges do not show any change after They are attempting to blame an instrumentation change on climate change.
Once again, mind-blowing malfeasance. But it gets much worse. The composite below shows all of the above in one graph. The average of all of the NOAA tide gauges is 1. Tide gauges show that sea level rise rates peaked around The claimed increase since is completely fraudulent.
Sea level rise — Wikipedia, the free encyclopedia. Every single thing NASA says about sea level is fraudulent. Their sea level operation is a propaganda outlet. They are not scientists and are not doing any legitimate science. Somehow, the focus of this agency has crept into the mission assigned to NOAA, including the monitoring of temperatures. This duplication is wasteful and unproductive to say the least, and is the real issue concerning NASA today. They need to again set their sights much higher, so to speak, in a manner consistent with their true purpose.
However, even that rate is too high. The measured number is more like 1. To inflate it to 1. I have lived in New York City my whole life.640 ford tractor wiring diagram
