Despite global warming, a region of the North Atlantic has been observed to cool, a phenomenon known as theáNorth Atlantic Warming Holeá(NAWH). The causes of the NAWH remain under debate but its emergence has been linked to a slowdown of the meridional circulation leading to a reduced ocean heat transport into the warming hole region. This note uses previously published evidence to suggest that the pattern of temperature change is not unique but may have been a recurring feature during the last century and a half, fluctuating between a positive and negative phase. It appears global warming has amplified one of these phases in the North Atlantic climate.
