Societal upheaval occurred across Eurasia in the sixth and seventh centuries. Tree-ring reconstructions suggest a period of pronounced cooling during this time associated with several volcanic eruptions. Climatic changes during the first half of the Common Era have been suggested to play a role in societal reorganizations in Europe1,2 and Asia3,4. In particular, the sixth century coincides with rising and falling civilizations1,2,3,4,5,6, pandemics7,8, human migration and political turmoil8,9… 

Was there a volcanic induced long lasting cooling over the Northern Hemisphere in the mid 6th–7th century?

Abstract. The climate in the Northern Hemisphere (NH) of the mid-6th century was one of the coldest during the last two millennia. The onset of this cold period is attributed to the volcanic double

Roman Warm Period and Late Antique Little Ice Age in an Earth System Model Large Ensemble

Changes in climate during the Roman Warm Period (RWP, 1–250 CE) and Late Antique Little Ice Age (LALIA, 536–660 CE) play a critical role in early societal evolution, but the climate differences

Explosive eruption of El Chichón volcano (Mexico) disrupted 6th century Maya civilization and contributed to global cooling

A remarkably long period of Northern Hemispheric cooling in the 6th century CE, which disrupted human societies across large parts of the globe, has been attributed to volcanic forcing of climate. A

Climate and society impacts in Scandinavia following the 536/540 CE volcanic double event

15 In the Northern Hemisphere, the mid-6th century was one of the coldest periods of the last 2000 years, as indicated by both proxy records and Earth System Model (ESM) simulations. This cold period

Accelerated Recent Warming and Temperature Variability Over the Past Eight Centuries in the Central Asian Altai From Blue Intensity in Tree Rings

Warming in Central Asia has been accelerating over the past three decades and is expected to intensify through the end of this century. Here, we develop a summer temperature reconstruction for

No evidence for globally coherent warm and cold periods over the preindustrial Common Era

No evidence for preindustrial globally coherent cold and warm epochs is found, indicating that preindustrial forcing was not sufficient to produce globally synchronous extreme temperatures at multidecadal and centennial timescales, and provides strong evidence that anthropogenic global warming is not only unparalleled in terms of absolute temperatures, but also unprecedented in spatial consistency within the context of the past 2,000 years.

The Climate Downturn of 536–50

This chapter surveys the evolution of research on the 536–50 CE climatic downturn and its human impacts. It presents the written evidence for atmospheric anomalies over the Mediterranean alongside

Recurrent transitions to Little Ice Age-like climatic regimes over the Holocene

A new 7500-year long palaeoclimate record tailored to detect LIA-like climatic regimes from northern European tree-ring data is produced and its results bridge the gaps between low- and high-resolution, precisely dated proxies and demonstrate the efficacy of slow and fast components of the climate system to generate LIA- like climate regimes.

Northern Hemisphere temperature anomalies during the 1450s period of ambiguous volcanic forcing

Ice core-based estimates of past volcanic eruptions are the main forcing of the last millennium climate model simulations. Understanding the timing and magnitude of eruptions is thus critical for

It is shown that large eruptions in the tropics and high latitudes were primary drivers of interannual-to-decadal temperature variability in the Northern Hemisphere during the past 2,500 years and cooling was proportional to the magnitude of volcanic forcing.
