cold blob
Definition
An anomalous, persistent region of cooler-than-average sea surface temperatures in the North Atlantic that has defied global warming trends.
A climatological phenomenon, also known as a 'warming hole,' believed to be linked to the weakening of the Atlantic Meridional Overturning Circulation (AMOC).
Examples
The North Atlantic's cold blob is basically the ocean's way of standing in the corner with its arms crossed while the rest of the planet throws a literal heat party.
Trying to explain the cold blob to someone is a great way to make them regret asking about your weekend plans at a dinner party.
If the ocean currents were a transit system, the cold blob is that one broken escalator that everyone tries to ignore until it eventually stops working entirely.
