Another scientist/study which is sounding the alarm on the danger we are in pertaining to the environment thru Global Warming. The exception here is that this scientist is saying that the acceleration of rising oceans due to warming is worse than scientists thought because of skewed reporting in the past. Observe.........



The report, reassessing records from more than 600 tidal gauges, found that readings from 1901-90 had over-estimated the rise in sea levels. Based on revised figures for those years, the acceleration since then was greater than so far assumed.

The report said the earlier readings were incomplete or skewed by local factors such as subsidence.

The new analysis "suggests that the acceleration in the past two decades is 25 percent higher than previously thought," Carling Hay, a Canadian scientist at Harvard University and lead author of the study in the journal Nature, told Reuters.

The study said sea level rise, caused by factors including a thaw of glaciers, averaged about 1.2 millimeters (0.05 inch) a year from 1901-90 - less than past estimates - and leapt to 3 mm a year in the past two decades, apparently linked to a quickening thaw of ice.


Nothing to see here, ma'am! Just some Doom Porn..........Well ATS, it seems that previous climate scientists made a mistake in their calculations which led to false conclusions concerning the rate of warming/melting. Now, based on new calculations, we're royally f'*!d, according to this new article. What says ATS?

The beach is still where it should be. It is not lapping up against or flowing over the road.

There is still sand on the beach to sunbathe.

Look, anyone living near the beach knows this is a crock of dog poo.

Climate changes. It always has and it always will. But right now, it does no seem tobe a problem, just go to the beach and reassure yourself.

I wish these paid scientists would understand that all we have to do is take the kids to the beach for a day to know how stupid this sort of thing is.

I'm in Florida, the beaches are gone now...not really

The depths at some hiking spots I hit that flood during high tide are still at the same ankle depths from 4 years ago.

I'm guessing the numbers don't jive with the agenda, so they changed the numbers. Laughable.

Gas prices drop, so try and create a tax to replace it. A tax that will save us all..amen!

Market makers playing games again. Similar to the fake wood burning disinfo put out, the wood burning stove bans put on mfgs. As if the select few who heat from wood are polluting beyond the levels caused by massive forest fires.

Quick summary of article:

1) they now say the early measurements of sea level in the 1st 1/2 of the century were incorrect.
2) this means total see level rise in last 20 years is greater than previous calculation.

So their conclusion is based on them finding out they're not so good at measuring sea level in the first place.

Current rate? 3 mm per year.

I would love to know how they measure sea level rate of change to that fine of a degree. Can anybody explain how they measure 3 mm of global sea level change?

The abstract of the actual article:
Probabilistic Reanalysis of Twentieth Century Sea Level Rise


Here we revisit estimates of twentieth-century GMSL rise using probabilistic techniques


From OP's original Yahoo article:


The report, reassessing records from more than 600 tidal gauges, found that readings from 1901-90 had over-estimated the rise in sea levels. Based on revised figures for those years, the acceleration since then was greater than so far assumed.


So 90 years worth of tidal gauge measurements from over 600 gauges were "reassessed" using a computer model. I guess when old fashioned measurements don't support the theory, "revisit" the measurement. I believe in climate change, but I don't cotton to shoddy science.

I don't think the rise is uniform all around the planet. I was in Martha's Vineyard last summer and I heard from some of the locals how water levels were increasing but in increments.

The beach I go to still is the same. Be going nearly 40 years now.

Unless the Sun or the Moon has changed its gravitational pull, and it hasn't, even oceans have to play by the rules.

The rules have not changed and thus, you can't get one ocean to be higher (on average) than another ocean. They are all connected North and South.

I am not at all impressed by the argument that starts with, "I heard from some of the locals." (Although it gave me a chuckle, especially when you add 'Martha's Vineyard')

You're correct, the effects are not uniform.

If memory serves, I believe some areas in the southern Pacific seem to be getting hit first and foremost. But, since sea level rise and fall is not uniform nor exactly the same all the time in the same areas (when we're talking in millimetres), whether or not that trend has increased to an average of 3mm/year is a whole other ballgame.

I have about as much faith in their ability to estimate an oceanic measurement trend of 3mm, as I do in their ability to estimate global mean temperature trends to tenths of a centigrade.

Both of which are being touted as so-called "certainties"... thereby giving way to delusions of illogical absolutes, IMO.

So because its ok in your area its not happening?
Are you really that naive?

its like saying global warming is false because its snowing in northern japan.

The world is bigger than your backyard

Sounds like Nancy Leider, I guess she is still around. Some spots rising, some lowering. So what would we do anyway, tax ourselves?

Oh and FYI:

- The margin of error for satellite global mean sea level is 3-4mm as stated from the NOAA.

- The margin of error for global mean temperatures is 2 degrees centigrade as stated from the IPCC.



So take from that what you will.

Oh for heavens sake! It is water! It finds its own level.

As I stated earlier, while their are tidal forces, all of the oceans are joined together.

So yes, in general terms, what happens at my beach, happens at yours.

You do know that water always finds its own level.

So which scientists are correct? This recent article in the NY Times says the sea levels rose less than they believed.

There are also gravitational and centrifugal forces. The Earth is not a perfect sphere, but an ellipsoid - it bulges slightly at the equator. Below are some gravitational anomalies impacting sea level:

Ah so it be. From reading the articles one would believe differently based on the spin.
