Scientists are sounding the alarm about unprecedented ocean temperatures, with experts expressing a mixture of concern and bewilderment at the magnitude and duration of the heat wave. From the North Atlantic to the waters around Antarctica, the oceans have been experiencing record-breaking warmth for nearly a year, leaving researchers scrambling for explanations.

 

Brian McNoldy, a hurricane expert at the University of Miami, describes the situation as "astonishing" and "like an omen of the future." His sentiments are echoed by marine scientists like Rob Larter in Cambridge, England, who expresses discomfort at the unexpected departure from normal conditions and the lack of convincing explanations.

 

The global warming caused by fossil fuel emissions is a primary driver of the rising ocean temperatures. The oceans, acting as a vast heat sink, absorb much of this excess heat. While this trend of warming oceans is not new, the intensity and rapidity of the recent increase have caught many scientists off guard.

One factor contributing to the warming in the North Atlantic may be a reduction in pollution, particularly sulfur dioxide emissions from container ships. With fewer aerosols in the atmosphere to create cloud cover, more solar radiation reaches the ocean's surface, further heating the water. However, this alone cannot account for the extreme heat observed.

 

Complex feedback loops within Earth's weather patterns also play a role. Unusually clear skies and reduced windiness in the North Atlantic have allowed more sunlight to penetrate the water, while also limiting the mixing of colder water from deeper layers.

 

The implications of these warmer ocean temperatures are far-reaching. They can fuel more intense and prolonged hurricane seasons, as well as contribute to the decline of Arctic sea ice. The latter, in turn, affects ocean circulation patterns, with potential consequences for global climate systems.

 

Of particular concern is the potential disruption of crucial ocean currents, such as the Atlantic Meridional Overturning Circulation (AMOC), which helps regulate climate around the world. As glaciers melt and introduce more freshwater into the Atlantic, there are fears that the AMOC could weaken, leading to dramatic shifts in weather patterns.

 

While it is too early to definitively attribute the ongoing heat wave to long-term changes in ocean currents, scientists warn of the possibility of far-reaching implications if such trends continue. The warming of the oceans underscores the urgent need for concerted global action to mitigate climate change and its impacts on marine ecosystems and weather patterns.

Also, the lower the CO2 retaining capacity. A dramatic example of this is what happens when someone opens a can of warm soda.

Two different mechanisms however: Carbon dioxide chemically dissolves. CO2+H20 <>H2CO3 + energy. So more heat in the water favors this reversible reaction going to the left.  In the the case of oxygen the O2 molecules are physically trapped in the H2O water molecules, that form hydrogen bonded cages. So with higher water temperatures the water molecules are moving faster which prevents  the hydrogen bonds  forming . So the the 02 escapes.

I'm not sure how much your observation has to do with thinking. At least with rational thinking. Like so many other denialists, you don't seem able to distinguish between climate and weather.

I believe it was sarcastic humor, with an emphasis on the humor, made me smile!

The issue isn't whether it was sarcasm; but, rather, what was the target of the sarcasm.

Ah, yes. Just watched the movie, “The Day After”. Fortunately, I am already living in warmer climate and will not have to seek refuge in Mexico.

'A hurricane expert from the university of Miami' is quoted as being behind many of these concerns. Not sure if that attaches authenticity to the foreboding expressed in the article.

Here's a link to another article. He doesn't feature in it at all but other climatologists do.

see for yourself what they think,

However, this alone cannot account for the extreme heat observed.  

 

This just shows that they are just Dreamers and on drugs,

The proof that what you're denying about aerosols is nonsense is very clear. Occasionally, when there's a truly catastrophic eruption of a volcano that sends huge quantities of aerosols into the atmosphere, what invariably follows is global cooling.

 

Effect of volcanic eruptions significantly underestimated in climate projections

Where and when a volcano erupts is not something that humans can control, but volcanoes do play an important role in the global climate system. When volcanoes erupt, they can spew sulphur gases into the upper atmosphere, which forms tiny particles called aerosols that reflect sunlight back into space. For very large eruptions, such as Mount Pinatubo in 1991, the volume of volcanic aerosols is so large that it single-handedly causes global temperatures to drop.

..and yet ships were encouraged, nay, mandated to have scrubbers fitted to reduce bad SO2. 🧐

there are intermediate processes not yet fully understood

But are definitely caused by "global warming"  and that warming is definitely caused by human activity ?

Really? It's false that scientists don't understand what "primary driver signifies? other Pavlovian comment from you.

Yes, definitely. I'm guessing you're about to invoke some critique based on the observation that no cause in the world can be characterized as 100% certain. If that were a meaningful comment, then all science and technology would be built on a heap of sand. In the real world, science and technology work, even nuclear physics are ultimately based on statistics.

Well that certainly reads like they haven't a clue, why, or how to, if even possible (it isn't) to stop what may or may not be a problem.

 

BUT ... need a concerted effort now to combat climate change, when they don't know why it might be warming, or how to stop it.

 

I did post a thread much earlier, that some are looking at, for a cause of things heating up, but more so, total disaster before climate change or global warming would be an issue.
