The Mysterious ‘Cold Blob’ Is Making Europe Sizzle: Scientists
News Desk
Islamabad: As Europe grapples with record-breaking temperatures, climate scientists say an unusual patch of cold water in the North Atlantic may be intensifying the continent’s extreme heat instead of providing relief.
The phenomenon, known as the “Atlantic cold blob,” lies between Greenland and Ireland, where ocean temperatures have cooled despite the steady rise in global temperatures.
While much of Europe has endured temperatures above 100°F (38°C), the cold-water region has stood out as one of the few places on Earth experiencing a long-term cooling trend.
Researchers say the anomaly is linked to melting ice from Greenland, which releases large volumes of freshwater into the North Atlantic. This influx disrupts the Atlantic Meridional Overturning Circulation (AMOC), a vital ocean current that transports warm tropical waters northward and helps regulate the climate.
According to scientific studies, the cold blob has cooled by as much as 0.9°C since 1900, even as average global sea-surface temperatures have risen by around 1°C over the same period.
Scientists believe this disruption may be contributing to more persistent high-pressure weather systems over Europe, increasing the likelihood of prolonged and intense heatwaves.
The warning comes as Europe experiences one of its most severe heatwaves on record, with France reporting record temperatures, hundreds of schools closing in Britain, and more than a thousand heat-related deaths reported across affected regions.
Climate experts caution that if the AMOC continues to weaken, or potentially shuts down later this century, the consequences could extend far beyond Europe. Possible impacts include more extreme weather across Europe, prolonged droughts in parts of Asia and Africa, and accelerated sea-level rise.
Current scientific assessments suggest there is roughly a 50% chance that the AMOC could experience a major collapse or shutdown during this century, underscoring growing concerns about the far-reaching effects of climate change.
