Satellite Snafu Masked True Sea Level Rise for Decades

Revised tallies confirm that the rate of sea level rise is accelerating as Earth warms and ice sheets thaw

The numbers didn’t add up. Even as Earth grew warmer and glaciers and ice sheets thawed, decades of satellite data seemed to show that the rate of sea-level rise was holding steady—or even declining.

Now, after puzzling over this discrepancy for years, scientists have identified its source: a problem with the calibration of a sensor on the first of several satellites launched to measure the height of the sea surface using radar. Adjusting the data to remove that error suggests that sea levels are indeed rising at faster rates each year

Not only temperatures misleading by satellite data because of this but now sea level rise.

Interesting story. Complete bullshit, but that's normal. A satellite measures its altitude by using what as a reference? Sea level. If the sea level rises, the satellite appears to be lower. Satellites are always getting lower as their orbit decays. Trying to measure down to less than a meter is complete bullshit as there are too many variables. All you have is a guess, based on an assumption, applied to a theory.

Tell me science rocks...do you fall for every lie you are told or just climate lies?

This latest story is absolutely typical of climate science, and how memes travel from one field to another.

Two years ago climate science was deeply embarrassed by The Pause and needed to do something about it during the run up to the Paris conference. Karl found a solution. He simply rearranged ocean warming by sketchy methods reduce the warming here and add it back there. Less variation, now the trend is averaged out and the 2000-2015 segment shows an upward trend.

Where did Karl get his inspiration from? The climategate emails show a concerted effort to get rid of the embarrassing warming from the 30s-50s, followed by the drop from the 50s-80s. How did they fix that? Adjustments again. Shave a little from the high side, add a little to the low side, and voila! No more obvious natural variation cycle. All warming, all the time. And the best part? By subtracting from the past and adding to the more recent they can claim the adjustments are neutral! Even though they change the trend and the shape of the graph.

Here are the changes since just 2008, there were many other adjustments before that, especially circa 2000 when homogenization methodologies we're deployed, and the mid 90s when the number of stations used was drastically reduced.

What does that have to do with satellite SLR, you say? This new article states the first decade of readings was too high but since then they are alright. It's the same old bait and switch. Reduce the past and it increases the trend. Now they can claim 'acceleration', which is important if their prophecies of doom are to have any chance of coming true.

I could go on and on. The GRACE mass measurements are totally dependent on rebound adjustments and have been scaled back dramatically recently with little public fanfare. The Arctic sea ice extent is only scary because of the very convenient start date of satellite coverage at the height of ice extent, and ignores the previous natural cycles of increase and decrease. The recent rise in OHC (ocean heat content) is publicized, the long and steady decrease from the start of our interglacial period is ignored. Now THAT is a scary topic if you care to think about it.

The information given to the public is always framed in such a way as to cause alarm. Often it is misleading, and the whole story leads to an opposite or at least different logical conclusion.

I live in Florida. Have lived here since 1968. I surfed here as a kid. Fished the shore lines almost the circumference of the state. Been to Crystal River, Apalatchicola Bay, the channels and flats of the sawgrass, and most other costal places here.

The water is at the same level on the bridges, the piers, the boat ramps, the locks, the flats, the power plants, the shores, the brackish rivers and inlets. Beach erosion only happens at hurricanes and returns naturally. Old houses and hotels are still there.

There is no evidence of sea level rise at all.

The reality is that the satellite was right before, but it didn't show what the global warming scam artists wanted it to, so they have tweaked it until it did. Typical.

Satellite has proven to have too many errors and problems. Finally at least the data is being improved so it is somewhat usable.

Ice sheets already in the water does not add in sea level rise.
Just like Ice cubes in a glass of water does not overflow the content in the glass when it melts.

???? So your saying a person doesn't affect the water level in a pool if he goes in slowly?

Are you planning on melting while you do that?

The actual water level is increased by the water displaced by your body compared to an equivalent volume of water. Since your body is mostly made of water, the part that floats is the difference. In other words, not very much!

Notice he never says how long this will take. The area where I live was once an inland sea. Who changed the climate to cause that?

Many people who make the point that melting ice from the tongue of an glacier that is already floating doesn't raise the sea level are being misleading by ignoring the fact that the ice originally came from the land.

What was the intention of your post?

edit- was it intentional misdirection or simple ignorance of the actual physics? Adding a person to the pool adds to the water level, whether they exhale and sink or just float on the top.

No it didn't it's sea water ice.
The snow that forms glaciers picks up the sea water and it's a continual cycle. It snows on land and the glaciers push it back out again.
The larger ones breaking off now are already in the sea.

Arctic ice adds nothing to the sea level because it is already in the water. Read the thread.

What do the global warming alarmists have to say about the couple that disappeared 75 years ago on a glacier and were recently discovered and buried?

Back then, the glacier was at the same point as today, so we have had global cooling for the past 75 years.

Only if you stay in it while its being filled up.
Other wise no.

Satellite Snafu Masked True Sea Level Rise for Decades

Revised tallies confirm that the rate of sea level rise is accelerating as Earth warms and ice sheets thaw

The numbers didn’t add up. Even as Earth grew warmer and glaciers and ice sheets thawed, decades of satellite data seemed to show that the rate of sea-level rise was holding steady—or even declining.

Now, after puzzling over this discrepancy for years, scientists have identified its source: a problem with the calibration of a sensor on the first of several satellites launched to measure the height of the sea surface using radar. Adjusting the data to remove that error suggests that sea levels are indeed rising at faster rates each year

Not only temperatures misleading by satellite data because of this but now sea level rise.

DECADES HUH? When was Poseidon/Topex launched? 1992.. What happened to the data in transition from Tidal Gauge to satellite in 1990s? The rate changed from about 1.9 or 2,0 mm/year to about 3.3mm/year IMMEDIATELY. Never fully explained. Nobody CARES if satellites give GREATER measurements. Don't want to look that gift horse in the mouth. Don't believe ACTUAL MEASUREMENTS of water height that don't agree with a "good thing".

So just the change in methodology introduced MOST of this "acceleration".. When in fact, the underlying disagreement probably stems from more "mid ocean" pools of water where the GREATEST rise rates are usually seen. Those mid ocean surface heights doesn't mean the COASTS are rising at that rate.

Sounds like more HONEST interpretation and analysis is due here before Gavin Schmitt is allowed to panic the herd once again.

You mean they doctored the data because it didn't support their hysterical claims.

This lie has already been exposed.

"Improved" means it's being doctored to fit the narrative.

It's the same thing they do with the temperature data.
