Climate is a great deal more complicated than MSM would have us believe!
No, I don't think so. The Atlantic Subpolar Gyre has experienced SST anomalies substantially colder than those observed today on numerous occasions between 1870 and 2026.
If the presence of a cold blob alone were sufficient evidence of a weakening or collapsing AMOC, then many of those earlier episodes should also have corresponded to major AMOC weakening events or even reversals-which is not supported by the observational record (at the meantime) . Most of that goes over the social media is (hype)⁹.
The following years rank among the coolest Subpolar Gyre SST states in my analysis (ordered from coolest to less cool): 1904, 1973, 1976, 1992, 1912, 1982, 1974, 1903, 1985, 1987, 1913, 1986, 1984, 1983, 1914, 1977, 1947, 1972, 1922, 1969, 1975, 1994, 2015, 1905, 1920, 1991, 1970, 1872, 1921, 1990, 1968, 1918, 1923, 1884, 1906, 2016, 1930, 1989, 1883, 1882, 1963, 1980, 1943.
A cold Subpolar Gyre may be consistent with a weaker AMOC, but it is not, by itself, definitive proof of AMOC weakening. Other oceanic and atmospheric processes can produce similar SST patterns.
The relationship is more nuanced than often portrayed on social media. attached is few example cold Atlantic subpolar gyre years and the heavens did Not fall to ground.
