According to a\u00a0new study<\/a><\/strong>, abrupt (\u00b11-2\u00b0C per century) shifts in North Atlantic Sea surface temperature (SST) have occurred routinely over the last 9000 years. These decadal- to centennial-scale climate changes were \u201cinduced by Holocene summer insolation and atmosphere-ocean internal variability.\u201d<\/p>\n\n\n\n

The average SST throughout the 8.2 ka fluctuation was 10.0\u00b0C. The average 4.2 ka SST was 8.1\u00b0C. And during the Little Ice Age (LIA, 1600-1900 CE) the North Atlantic SSTs averaged 7.5\u00b0C.<\/p>\n\n\n\n

Since 1900, SSTs have been stable to declining, suggesting the modern period is the coldest of the Holocene.<\/p>\n\n\n\n

North Atlantic SSTs have not warmed (net) in the last 120 years, or since the late 1800s.<\/p>\n\n\n\n
