Modern ‘Warmth’ A Brief Excursion From 8,000-Year (Continuing) Cooling Trend

by Kenneth Richard, March 20, 2017

According to an estimate of global sea surface temperature (SST) changes during the last 2,000 years (“Robust global ocean cooling trend for the pre-industrial Common Era“), the addition of the last 2 centuries (1800 to 2000 C.E.) of relatively modest SST warming only changes the overall per-millennium global cooling trend (~0.4°C) by one tenth of one degree.  In other words, using a long-term perspective, the Holocene cooling trend has continued largely uninterrupted during the last two centuries.
