Current climate model simulations overestimate future sea-level rise
phys.org ^ | APRIL 9, 2021 | Utrecht University, Utrecht University Faculty of Science

Posted on 04/10/2021 1:27:06 PM PDT by BenLurkin

The melting rate of the Antarctic ice sheet is mainly controlled by the increase of ocean temperatures surrounding Antarctica. Using a new, higher-resolution climate model simulation, scientists from Utrecht University found a much slower ocean temperature increase compared to current simulations with a coarser resolution. Consequently, the projected sea-level rise in 100 years is about 25% lower than expected from the current simulations.

The new high-resolution model takes into account ocean eddy processes. An eddy is a large (10-200 km) swirling and turbulent feature in the ocean circulation, which contributes to the transport of heat and salt. Adding ocean eddies into the simulation leads to a more realistic representation of the ocean temperatures surrounding Antarctica, which is key for determining the mass loss of the Antarctic ice sheet.

The current climate model simulations, which do not take ocean eddies into account, project that the ocean temperatures around Antarctica are increasing under climate change. The new high-resolution simulation shows quite different behavior and some regions near Antarctica even cool under climate change...

The new high-resolution model projects a smaller mass loss as a result of ice-shelf melt: only one third compared to current climate models. This reduces the projected global sea-level rise by 25% in the upcoming 100 years...

It took the team about one year to complete the high-resolution model simulation on the national supercomputer at SURFsara in Amsterdam.

I thought in the new era that Science and Truth is always settled by consensus ?

Climate model simulations overstate (everything).

Did you vever fill a glass with water and ice? When the ice melted did the glass “overflow”? No of course not.. the displacement by the ice was equal to the fluid amount.. It is no difference with the glaciers...So even IF they really did melt, NYC is safe

Climate change is like racism a money maker

Somebody please tell me when one of these vaunted climate models have been remotely close to accurate.

Good news for Palm Beach residents. New York will still proceed building a sea wall around The Burroughs though.

Of course, the year-2100 prediction is for 2 feet of ocean-level rise. Enough to make a 10 foot storm surge feel like a 12 foot storm surge. Not enough to submerge any vegetated coastal islet... Some tiny, desert, uninhabited reef islands may be in trouble.

Between living in Hawaii and visiting for over 40 years there is the same stake stuck in a concrete post at the marina near Kaneohe. The sea level hasn’t moved.

Scriptures say GOD set the boundaries of the sea. It isn’t going anywhere.

The problem is that they're finding underwater volcanos so the warming is from below...not from the atmosphere....and they have known this for 100 years.

Hint...Greenland was once Green.

Your illustration doesn't hold up for glaciers or for Antarctica. When the ice starts on land and then melts or breaks off into the sea, it will cause a rise in sea level, much the same as if you take a full glass of water and add an ice cube to it. It will overflow.

I dont believe that glaciers are on land photoes show the ice is in water

See this article in Wikipedia:

https://en.wikipedia.org/wiki/Glacier

Note especially this sentence in the first paragraph:

“Glaciers form only on land and are distinct from the much thinner sea ice and lake ice that forms on the surface of bodies of water.”

The sea surfaces are quite a few square meters. More than one hundred thousand. If all the ice melted, the water would do a complex maneuver called leveling, over all of these hundreds of square meters.
