Social Media Posted February 28 Share Posted February 28 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. 29.02.24 Source Link to comment Share on other sites More sharing options...

I'm sure they have the plans already in progress, probably for the Maldives, where they can measure the temperature for themselves by swimming in it. As usual "scientists claim" but not a single solution to be uttered by them. Can't keep the peasants in their place if they aren't afraid of something. 3 4 1 1 3 7 Link to comment Share on other sites More sharing options...

In this case it means that global warming is the ultimate source of this anomalous rise in temperature. But there are intermediate processes not yet fully understood that have led to the current situation. 3 2 1 1 2 1 Link to comment Share on other sites More sharing options...

morrobay Posted February 29 Share Posted February 29 1 hour ago, placeholder said: 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. 1 1 Link to comment Share on other sites More sharing options...

But, don't think that the oceans are actually releasing CO2 into the atmosphere. Certainly not on balance. Rather the uptake of CO2 is being slowed. Unlike oxygen, CO2 constitutes a double hex. Elevated levels of carbonic acid in the water lead to all sorts of dire consequences thanks to the lowered PH. Among other things, it inhibits mollusks, corals, foraminifera and other sea creatures from making shells. The level of Carbonic acid in the sea is still rising but at a somewhat lowered pace as the oceans get warmer. So the lessened uptake keeps more CO2 in the atmosphere than would otherwise be the case. 1 2 1 Link to comment Share on other sites More sharing options...

Fortunately, I am already living in warmer climate and will not have to seek refuge in Mexico. For those of you who may be puzzled by Wrwest's comments in a thread about a warming North Atlantic, here's a summary of the movie I believe he's referring to: "The Day After Tomorrow is a 2004 American science fiction disaster film[2] conceived, co-written, directed, co-produced by Roland Emmerich, based on the 1999 book The Coming Global Superstorm by Art Bell and Whitley Strieber, and starring Dennis Quaid, Jake Gyllenhaal, Sela Ward, Emmy Rossum, and Ian Holm. The film depicts catastrophic climatic effects following the disruption of the North Atlantic Ocean circulation, in which a series of extreme weather events usher in climate change and lead to a new ice age.[3][4]" https://en.wikipedia.org/wiki/The_Day_After_Tomorrow 1 1 1 Link to comment Share on other sites More sharing options...

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. https://www.cam.ac.uk/research/news/effect-of-volcanic-eruptions-significantly-underestimated-in-climate-projections 1 1 Link to comment Share on other sites More sharing options...

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. 1 Link to comment Share on other sites More sharing options...

KhunLA Posted February 29 Share Posted February 29 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. 2 Link to comment Share on other sites More sharing options...
