Per Schmidt's unexpected/unexplained surplus 0.2C anomaly those who claim the El Nino to La Nina shift will wash it away are ignoring...
that even if 2024 SST cooling proceeds according to 2016's ENSO transition, by year's end we'll find ourselves at or above 2015/16 El Nino SSTa level.

Arguably #3 is the worst - it should be phrased "It's not that bad"...
... especially when promoted by climate scientists making Anti-Doomism talking points, as if censoring how dire our circumstances are serves any good purpose whatsoever.

As a scientist you appear to be playing into the popular unwillingness to understand just how dire our circumstances are, which is how our circumstances became so dire, as identified by Uncharted Territory/Waters.
My simple question is Why?... as a long ago NASA GISS intern/Wally's World student.

Surely you understand that the Urgency & Priority of Now has remained deliberately diluted for 35 years.
Between Rahmstorf's latest, the sleeping giant Antarctica awakening, AMOC/SMOC slowdown(s), teleconnections & Uncharted Territory...
2 years may in fact decide it, no?

Quick Take:
...Various lines of evidence outline that ocean warming reached the highest observed levels in 2023, continuing the ongoing & accelerating trend that models suggest will continue into the future in the absence of drastic emissions reductions....
MIA? AMOC/SMOC rate⬇️s as of '90

That's odd.
Someone named Gavin Schmidt's Nature letter ID'ed being in "Uncharted Territory," not being able to account for 2023's 0.2C degree surplus anomaly as perhaps being the discovery of a knowledge gap, for the 1st time in 40 years.
But if GCMers all say "Don't Worry Be Happy"... Why worry?
🙄
April 5, 2024 at 10:52 PM
Hmmm, yeah well... it's likely worse than that.
Between AMOC (12%) & SMOC (30%) Slowdowns since 1990 & the likely "all of the above Acceleration answer (not just A for Aerosols per Hansen's latest)... incl. Antarctic Circumpolar Current's 5M year "acceleration" history...
Welcome to Wally's World!

As AR Watch for Antarctic Feb/Mar "anomalous" warming/melt events winds down...
...anomalous SSTa Cold Blob Watch continues, as that serves as an indicator of overturning/circ. slowdown for AMOC.
As Jennifer Francis points out, circumstances are different...

Dare one suggest...
It's a pity that Revkin's interview did not feature more SSTa questions of yourself & Schmidt related to what GCM's may be missing.
As a long ago NASA GISS intern/Wally's World student:
Out: Beware melt pulses
In: Beware persistent SST Cold Blobs
OHC circulation slowdowns matter!
March 25, 2024 at 5:05 PM
Inre: Bille's point, the Urgency & Priority of Now for examining those options, ASAP, has never been higher.
Invoking @climateofgavin.bsky.social 's 3/21/24 Nature letter, per unexpectedly hitting "uncharted territory" per the hows & whys of 2023's accelerating(?) change:
Yes! Now!

Know what's even funnier?
Pretty sure you X blocked me for posting about 2023's off the chart SSTa & ocean circulation slowdown studies, related to AMOC/Antarctic overturning/circulation slowdown, including Rahmstorf & England vids.
Didn't mind as have another X account... but wicked 🤣 ironic, eh?

So timely & apt esp. related to Schmidt's latest quotables.
OTOH there's the "it's too late, why bother?" Doomism promoted by Big Oil.
OTO the "learning curve" passing Doomism per sorting out observations & science.
Censoring "learning" Doomism censors science & dilutes ASAP urgency.

March 20, 2024 at 3:47 PM
Yes, per not being able to account for 0.2C warming.
Unknown per why, but as Schmidt hints "likely."
Per prior reply, there's a dif. between uncertainty & being doomed. A timely & apt nature letter:

As much as AMOC Collapse made a big media "splash," Slowdowns matter a lot also, given ocean conveyor system where slowing inputs beget slowing outputs.
With that in mind, this 2023 "cool-blob" somewhat jumped off FT's map per Antarctica regime shift as of 2020 (2015?) & per SSTa shifts since 2010.

As a NASA GISS intern who also took Wally's World (Broecker) courses 33+ years back... Thank You!
Hansen et al's 2016 "Ice Melt" update & followup to his "Aerosols/Pipeline" paper will address ocean circulation issues.
AMOC has slowed 12-15% & Antarctica 30% since 1990s, pre-2023...

Here are two 2022 refs/reviews from prior reply. URL links are in Alt-text.
Interpretation is part of the Antarctic regime shift that peer viewed science needs to catch up with & sort out.
Paleo-climate record IDs a multi-decadal melt lag w/ the Arctic, which has dif. circumstances per "why ARs?"

Maybe if we used a different projection?
Waiting to see a 2024 trifecta of Atmospheric Rivers... given "beyond ENSO" uptick of such SSTa driven Antarctic events..
Per Berra'isms "The future ain't what it used to be" & past is no longer prologue.
I've shared w/ links. Thank You!

There is more to explain.
I'm watching it thru the Welcome to Wally's World SST context of ocean overturning/circulation slowdown(s), the subject of Hansen's next discuss paper.
Even if 2024 follows 2016's cool-off SSTa temps will likely be higher by 2025 than they were in Jan. '16.

With 4 such AP events in 4 years (w/ '22 & '20), or 5 incl. March '22 for E. Antarctica, jet stream change seems to be 4th element of beyond ENSO Antarctic Regime Shift...
coupled with record sea ice extent lows, SSTa & overturning/circumpolar circulation slowdown.
Given feedbacks... expect "more."
March 10, 2024 at 2:24 PM
Thanks to your updates, I've been looking at SSTa & jet stream role....
having followed Dr. Jennifer Francis's Arctic amplification/jet stream discoveries as of 2011.
SSTa has since taken on a bigger role, as one would expect also for Antarctic.
Context, with a glance back to mid-March 2022 "event."

Agreed.
MIA is how slowed inputs/inflows to ocean conveyor (AMOC + Antarctica) system have slowed cold water upwellings also.
