The mysterious "cold blob" has puzzled scientists for years, but a new study suggests it could be a dangerous sign of a larger climate crisis unfolding beneath the surface of the Atlantic Ocean. Located near Greenland and Iceland, this region—known as the "cold blob" or "warming hole"—has been cooling steadily since the early 20th century, defying the overall trend of rising ocean temperatures. This anomaly has sparked intense scientific debate, with researchers initially proposing multiple theories about its cause. However, recent findings indicate that the phenomenon might be linked to the weakening of a critical oceanic current system known as the Atlantic Meridional Overturning Circulation (AMOC).
The AMOC functions much like a conveyor belt, transporting warm water from the tropics toward the North Atlantic, where it cools, sinks, and returns southward. This process plays a vital role in regulating global weather patterns and maintaining stable sea levels. Recent studies have shown that the AMOC has been slowing down due to climate change, primarily driven by human activities such as greenhouse gas emissions. The melting of polar ice sheets adds more freshwater into the ocean, disrupting the delicate balance of salinity and temperature that powers the AMOC. As a result, the flow of this massive circulation system has weakened significantly over the past few decades.
The cold blob, located just north of the equator, has become one of the most visible signs of this slowdown. Unlike typical surface-level cooling caused by atmospheric conditions, the cold blob extends deep into the ocean, far beyond areas influenced by wind and cloud cover. This discovery has led scientists to conclude that the AMOC's weakening is likely responsible for the unusual cooling pattern. Researchers at the Potsdam Institute for Climate Impact Research, including Professor Stefan Rahmstorf, argue that the data strongly supports this connection. They note that the observed changes in ocean temperature align with models predicting a decline in AMOC strength, suggesting that the system is approaching a tipping point.
If the AMOC were to collapse entirely, the consequences would be catastrophic. A complete shutdown of this circulation would disrupt global weather systems, leading to extreme cold snaps in parts of Europe, severe droughts in Africa, and accelerated sea level rise along the eastern coast of the United States. These effects could trigger a cascade of environmental and social disruptions, potentially worsening existing climate challenges. Some scientists warn that the AMOC may already be close to irreversible collapse, with the potential for rapid and unpredictable changes in the coming decades.
While the latest research provides compelling evidence linking the cold blob to AMOC weakening, some experts caution against overinterpreting the findings. René van Westen, a researcher at Utrecht University, acknowledges that earlier explanations focused solely on atmospheric factors. However, he agrees that the new study’s results, derived from multiple independent datasets, offer stronger support for the AMOC hypothesis. Similarly, David Thornalley of University College London emphasizes the importance of continued monitoring, noting that while the available data is valuable, it remains limited in scope. He stresses that further research will be necessary to fully understand the implications of these changes.
As the scientific community continues to investigate the cold blob and its broader implications, the urgency of addressing climate change has never been greater. With global temperatures projected to surpass 1.5 degrees Celsius above pre-industrial levels within the next decade, the need for immediate action to reduce greenhouse gas emissions has never been more pressing. While the full extent of the AMOC’s decline remains uncertain, the growing body of evidence suggests that the world is standing at a critical juncture—one that could shape the future of our planet for generations to come.

To je povzročilo skrbi med klimatologi. V argentijskih raziskovalnih bazah Esperanza je bila zabeležena temperatura 15,4°C – dva stopnja nad prejšnjim rekordom iz leta 1998. Temperature so bile nad ničlo že tri tedne zapored, kar je zelo neobičajno za to časovno obdobje. Vidni učinki vključujejo izpostavljeno tla namesto snežnega pokriva in toplo ledeno vodo na vrhovih lednikov, ki bi običajno zbrali nov snežni pokriv. Znanstveniki opozarjajo, da so ti topli valovi nekaj, kar ni le kratkoročna vremenska anomalija.
Ocena pristranskosti (Sredina): Članek poudarja opozorilo na temperaturno povečanje in citira znanstvenike, ki izražajo skrbi, kar predlaguje okoljsko usmerjenost, skladno z naprednimi vrednotami. Kljub temu ostaja v večini dejanskih podatkov brez izraženega jezika, ki bi bil v nasprotnem smislu ali izbire virov.

N1 HrvatskaNeodvisenSredinaDejstva 85Objektivnost 85pred 24 dneviStudija je identificirala 'hladno mesto' v severnem Atlantiku, južno od Grönlandije in Islandije, kot znak potencialnih točk preklopa v klimi. Ta območje je pohladnilo skoraj za en stopnjo Celzija od leta 1900, nasprotno kot globalni trend segrevanja. Raziskovalci predlagajo, da je to hlajenje verjetno posledica oslabitev Atlantskega meridionalnega prekrivnega tokovnega sistema (AMOC), pomembnega oceanografskega tokovnega sistema, ki prenaša toploto po vsem svetu. To bi lahko imelo resne posledice za prihodnost planeta.
