"The latest research finds the Gulf Stream has warmed faster than the global ocean over the past two decades, and has shifted toward the #AtlanticCoast.
"Scientists say the ocean current, which carries tropical water up the #EasternSeaboard, has warmed two degrees Fahrenheit since 2001 and could be pushing warmer water into the #GulfOfMaine.
"Robert Todd, an associate scientist with the Woods Hole Oceanographic Institution, said years of data collection confirm what climate models predicted.
"'Long-term ocean observing really is important,' said Todd, 'and we need to keep making those observations so we can understand what’s actually happening in the climate system.'
"Todd said #OceanTemperatures are steadily rising as a result of human activities. He said the findings could determine how changes in the Gulf Stream will impact Maine’s coastal industries.
"The Woods Hole study relied on more than 25,000 ocean temperature and salinity observations collected through the Argo Program — an array of some 4,000 floating robots throughout the global ocean.
"In addition, underwater gliders have slowly navigated the Gulf Stream — revealing warm rings of water, which Todd says could enter the Gulf of Maine and alter marine #environments and species.
"'You can imagine if you have an organism that likes cold water, and suddenly the water is a whole lot warmer because this ring was there,' said Todd, 'those organisms might not be there anymore or might suffer — and then, the fisheries associated with that would suffer.'
"The Gulf of Maine — which stretches from #CapeCod in #Massachusetts to #NovaScotia, #Canada — is already considered one of the fastest-warming ocean regions on the planet.
"Todd said the data collected is shared in real time with scientists around the world."
Forebodings of the next extinction-level events (#ELE's)
"South-east #Australia#Marine Heatwave forecast to be literally off the scale
Patch of #Tasman sea expected to warm over spring and summer to temperatures that risk significant losses to sea life" 1)
“We didn’t account for anomalies that high when we developed this ... it could be 3C, it could be 3.5C, but we can’t see how high it goes,” said Oceanographer Grant Smith.
"...we’d expect to see impacts on remaining #KelpForest in the region,” he said, noting that 👉 #Tasmania’s giant kelp species had already lost 95% 👈 of its historical range."
Due to #OceanWarming, which I covered here 2), we might never get to know the 91% of #MarineLife that is still unclassified. 3)
"South-east #Australia#marine#heatwave forecast to be literally off the scale - Patch of Tasman sea expected to warm over spring and summer to temperatures that risk significant losses to sea life
Australia’s south-east could be in for a marine heatwave that is literally off the scale, raising the prospect of significant losses in fishing and aquaculture.
The Bureau of Meteorology has forecast a patch of the Tasman Sea off Tasmania and Victoria could be at least 2.5C above average from September to February, and it could get hotter.
Oceanographer Grant Smith said the colour-coded scale the bureau uses to map forecast sea surface temperature anomalies stops at 2.5C. “We didn’t account for anomalies that high when we developed this ... it could be 3C, it could be 3.5C, but we can’t see how high it goes,” he said.

South-eastern Australia is a known climate change hotspot with its waters warming about four times faster than the global average."
New #Antarctic extremes 'virtually certain' as world warms
Date: August 8, 2023
Source: University of Exeter
Summary:
Extreme events in #Antarctica such as ocean heatwaves and ice loss will almost certainly become more common and more severe, researchers say.
"'Antarctic change has global implications,' said lead author Professor Martin Siegert, from the University of Exeter. 'Reducing greenhouse gas emissions to net zero is our best hope of preserving Antarctica, and this must matter to every country -- and individual -- on the planet.'"
Next to rising #GHG emissions, changing clouds by reduced #aerosol#pollution due to the phasing out of high-sulfur ship fuel are to blame (at least partially) for the recent record-breaking North Atlantic #OceanWarming.
Florida coral is dying after water temperatures exceed 100 degrees.
Water temperatures in the Florida Keys hit 101 degrees late last month, causing rapid coral death.
Now, researchers are scrambling to bring surviving species to land to preserve them in the event of even higher temperatures. While coral make up less than 1% of all ocean life, a quarter of marine species rely on them to live.
#Südamerika erlebt gerade eines der extremsten Ereignisse, das die Welt je gesehen hat! Temperaturen von bis zu 39°C in den chilenischen Anden mitten im #Winter! Wärmer als Südeuropa im Hochsommer - dieses Ereignis schreibt alle Klimabücher neu. #Klimakrise#Hitze

#SouthAmerica and parts of the #US are being boiled - literally.
In the Southern hemisphere, it is (theoretically) winter at present. But thre are presently up to 39°C / 102°C Fahrenheit in the #Andes of #Chile are unprecedented.
How many animals, and people, are going to die due to this heat!

Florida ocean records ‘unprecedented’ temperatures similar to a hot tub
"The surface ocean temperature around the Florida Keys soared to 101.19F (38.43C) this week, in what could be a global record as ocean heat around the state reaches unprecedented extremes."
I have posted two threads on #OceanWarming 1) 2) and I am aware that just thinking of the factors in a natural reflection is not scientific.
However, the breakdown of the potential #NorthAtlanticConveyerBelt has been discussed since the early 1990's at the latest.
Despite this, it is my impression that no model foresaw this happening in such a short time frame.

🌡️ Die Erhitzung im Atlantik ist dramatisch:
"Es ist im Moment sogar so, dass wir dort Temperaturen haben, die eigentlich in den letzten 100 Jahren da gar nicht vorgekommen sind – vielleicht noch länger. Und so kann man gar nicht wissen, wie die Arten damit umgehen."

“The average for this time of year, over the past three decades, is 71 degrees Fahrenheit. Now it is 73. That two-degree difference reflects a gargantuan amount of extra energy stored in the ocean. The Atlantic has been riding a wave of extreme heat since last year. And as summer sets in, the temperature will climb.”
