Volcanoes linked with cooling

After more than four years of virtual collaboration, our Ocean2k Working Group has published a study in Nature Geoscience showing an 1800 year-long robust cooling trend in global sea surface temperatures. They link the coolest period, between 801 to 1800 CE, with an increase in volcanic eruptions. From the 1800s onward, the cooling trend stops and a statistically significant warming is seen, likely due to human-caused global warming.

This study is the missing ocean component to the PAGES 2k Consortium's 2013 Nature Geoscience study into land-based temperatures over the last 2,000 years.
