*The Ocean Is Looking More Menacing*
June 1, 2023
David Wallace-Wells
There are a lot of unsettling signals coming from the world’s oceans
right now.
Even for those of us who watch things like temperature anomalies and
extreme weather events as likely portents of the climate to come, the
off-the-charts rise of global sea surface temperature this spring has
been eye-popping. As is much of the language recently used to describe
it: “record breaking,” “huge,” “alarming,” “unprecedented,” “uncharted,”
“an extreme event at a global scale.” Perhaps most simply: “trouble.”
In mid-March, measures of global sea-surface temperature plotted against
recent years took a sharp turn away from the pack. By April 1, it had
hit a record high. Then, in line with historical seasonal patterns, it
began to slightly decline — only to reverse course in the middle of the
month, heating up to about three quarters of a degree above the
1982-2011 mean. That represented what Robert Rohde, the lead scientist
of the Berkeley Earth institute, identified as the largest global ocean
temperature anomaly on record.
Three-quarters of a degree might not sound like much, and the size of
the anomaly has since shrunk, to a temperature level only about
one-quarter degree above the previous record. But scientists talk about
global temperature rise using very small numbers — sometimes describing
the difference between 1 degree Celsius of warming and 2 as an almost
civilization-scale chasm — and often find themselves gobsmacked when
local surface temperature records are broken by even one full degree.
Because the oceans are so large, it takes a lot more to heat them —
which makes any extremes even harder to produce, and therefore more
startling.
The recent temperature spikes are partly explained by the apparent shift
from a “La Niña” cycle in the Pacific, which suppresses global
temperatures, to an “El Niño” cycle, which elevates them. But this
April, huge areas of the world’s oceans were two degrees above the
1971-2000 average. In places off the Pacific coast of South America it
was as much as five degrees higher. Sea-surface temperatures off the
Atlantic coast of North America were almost 14 degrees above the
1981-2011 average.
What do you call the arrival of events that have been predicted but,
when predicted, were described as distressing or even terrifying? The
question now governs an awful lot of our experience of the warming
world, which confronts us routinely with events we may have known to
expect but for which nevertheless we find ourselves often woefully
underprepared — politically, socially, emotionally, and with inadequate
built and human infrastructure.
And then there are the genuine surprises, since even in a world of
loudly broadcast climate science, regular U.N. warnings, and even naked
alarmism, there are still, pretty frequently, truly unexpected extremes.
The 2021 heat wave in the Pacific Northwest and Canada, for instance,
was judged at the time to be a once-in-a-millennium event, yet it was
followed less than two years later by a heat event in May that was
nearly as extreme. Another may be arriving this week to the east.
But some news from ocean science may prove more surprising still —
perhaps genuinely paradigm-shifting. In a paper published in March,
researchers suggested that under a high-emissions scenario, rapid
melting of Antarctic ice could slow deepwater formation in the Southern
Ocean by more than 40 percent by 2050, disrupting the “conveyor belt”
that regulates and stabilizes not just the temperature of the oceans but
much of the world’s weather systems. And after 2050? This key part of
the circulation of the Southern Ocean “looks headed towards collapse
this century,” study coordinator Matthew England told Yale Environment
360. “And once collapsed, it would most likely stay collapsed until
Antarctic melting stopped. At current projections that could be
centuries away.”
Then, last week, some of the same researchers confirmed that the process
was already unfolding — in fact, that the Southern Ocean overturning
circulation had already slowed by as much as 30 percent since the 1990s.
“The model projections of rapid change in the deep ocean circulation in
response to melting of Antarctic ice might, if anything, have been
conservative,” said Steve Rintoul, a co-author on the new paper and one
of the researchers who’d published the previous paper back in March.
“Changes have already happened in the ocean that were not projected to
happen until a few decades from now.”
The oceans have lately produced a number of other curiosities to chew
over, as well: record low levels of Antarctic sea ice, with the “mind
boggling fast reduction” scientists have called “gobsmacking” also
potentially signaling a “regime shift” in the oceans; some perplexing
trends in the El Niño-La Niña cycle, suggesting that warming may be
making La Niñas more frequent and thereby scrambling some expectations
for future extreme weather; and questions about the role large icebergs
may be playing in the warming patterns of the world’s water.
Some of this research (on the circulation patterns of the Southern
Ocean) is relatively novel. Some of it (about El Niño patterns and
icebergs) is considerably more tentative or speculative. And the
findings haven’t yet been stitched into a comprehensive picture of the
changing dynamics of the world’s oceans, which means we don’t yet know
exactly how precisely to revise our understanding of the near future as
a result. But taken altogether, they do suggest that those ocean
dynamics are changing — possibly pretty quickly. Reflecting on the
anomalies and what’s to come, later this year, Jennifer Francis of the
Woodwell Climate Research Center recently advised, “Expect chaos.”
On some level, this shouldn’t surprise us. Just under 90 percent of the
additional heat caused by global warming goes into the ocean, according
to one recent tabulation, which also found that the planet accumulated
nearly as much additional heat in the past 15 years as it had over the
previous 45. (Perhaps this should not be too surprising, given that
almost third of all emissions ever produced from the burning of fossil
fuels in the history of humanity were expelled into the atmosphere in
those 15 years.)
It’s for this reason that the ocean is often described as a kind of
release valve for warming — or sometimes a temperature sink — sparing
our lands of some considerable additional heat. But what this means for
oceans is that they are dealing with about 15 times as much impact and
disruption from heat as those of us walking the earth and breathing air.
And that, probably, we should be spending a lot more time looking there,
in the world’s water, for the clearest signs of planetary distress.
“Although man’s record as a steward of the natural resources of the
earth has been a discouraging one, there has long been a certain comfort
in the belief that the sea, at least, was inviolate, beyond man’s
ability to change and to despoil,” Rachel Carson wrote in a preface to
“The Sea Around Us,” which won her a National Book Award and spent 86
weeks on the New York Times best-seller list, well before the
publication of “Silent Spring.” “This belief, unfortunately, has proved
to be naïve.”

*Why are massive ocean currents slowing down?*
Australian Academy of Science
Mar 29, 2023 #nature #oceans #climatechange
A new study makes a dire prediction about the effects of Antarctic
meltwater on the deep ocean currents and the resulting impact on marine
ecosystems.
Scientia Professor and Academy Fellow Professor Matthew England of UNSW
Sydney, and Dr Adele Morrison, DECRA Research Fellow at the ANU, explain
the results of their landmark paper, published today in Nature: Is the
Southern Ocean about to have its own 'Day After Tomorrow' moment?
Our video, fact-checked by our expert Fellows, explains how these
changes would profoundly alter the ocean's overturning of heat,
freshwater, oxygen, carbon and nutrients, with impacts felt throughout
the global ocean for centuries to come.

*Corporate Amazon workers protest company’s climate impact and
return-to-office mandate in walkout*
By ED KOMENDA
SEATTLE (AP) — Telling executives to “strive harder,” hundreds of
corporate Amazon workers protested what they decried as the company’s
lack of progress on climate goals and an inequitable return-to-office
mandate during a lunchtime demonstration at its Seattle headquarters
Wednesday.
The protest came a week after Amazon’s annual shareholder meeting and a
month after a policy took effect returning workers to the office three
days per week. Previously, team leaders were allowed to determine how
their charges worked.
The employees chanted their disappointment with the pace of the
company’s efforts to reduce its carbon footprint — “Emissions climbing,
time to act” — and urged Amazon to return authority to team leaders when
it comes to work location.
Wearing a black pirate hat and red coat, Church Hindley, a quality
assurance engineer, said working from home allowed him to live a better,
healthier life.
“I’m out here because I refuse to just sit idly by while mandates are
dictated from above down that don’t make sense and hurt the planet, hurt
families and individual lives,” Hindley said. “And just to get us into a
seat at the office for their tax incentives.”
In a statement, Amazon said it supported workers expressing opinions.
As of Wednesday morning, organizers estimated more than 1,900 employees
pledged to walk out around the world, with about 900 in Seattle. Many
participated remotely, but hundreds gathered at the Amazon Spheres — a
four-story structure in downtown Seattle that from the outside looks
like three connected glass orbs.

Christopher Flavelle reported from Washington and Jack Healy from Phoenix.
June 1, 2023
Arizona has determined that there is not enough groundwater for all of
the housing construction that has already been approved in the Phoenix
area, and will stop developers from building some new subdivisions, a
sign of looming trouble in the West and other places where overuse,
drought and climate change are straining water supplies.
