  • Source Integrity: Verified strictly against primary headline reporting under zero-hallucination protocols.

An ocean 'cold blob' in the North Atlantic is appearing as an accomplice to European heatwaves. This phenomenon is associated with the weakening of a giant ocean system that typically keeps Europe warm, as well as the potential for the Gulf Stream to shift its course toward Canada.

Coverage from Nature, Yahoo, and The Week emphasizes the role of the Atlantic Meridional Overturning Circulation (AMOC) and its response to historical freshwater increases. The Climate Impact Company specifically correlates the 'North Atlantic Warm Hole' with European heat risk.

According to the Climate Impact Company, observers should expect a repeat of these heat risks in July and August.
