Northern Hemisphere summer temperatures over the past 8000 years have been paced by the slow decrease in summer insolation resulting from the precession of the equinoxes. However, the causes of superposed century‐scale cold summer anomalies, of which the Little Ice Age (LIA) is the most extreme, remain debated, largely because the natural forcings are either weak or, in the case of volcanism, short lived. Here we present precisely dated records of ice‐cap growth from Arctic Canada and Iceland… 
Volcano-induced regime shifts in millennial tree-ring chronologies from northeastern North America
TLDR
A new network of millennial tree-ring chronologies from the taiga of northeastern North America is presented, which fills a wide gap in the network of the Northern Hemisphere's chronologies suitable for temperature reconstructions and supports the hypothesis that volcanoes triggered both the onset and the coldest episode of the Little Ice Age.
Evidence for extreme export of Arctic sea ice leading the abrupt onset of the Little Ice Age
TLDR
Recon reconstructing sea ice exported from the Arctic Ocean over the past 1400 years finds robust evidence for extreme export of sea ice commencing abruptly around 1300 CE and terminating in the late 1300s, providing evidence that marked climate changes may not require an external trigger.
Amplified Inception of European Little Ice Age by Sea Ice–Ocean–Atmosphere Feedbacks
AbstractThe inception of the Little Ice Age (~1400–1700 AD) is believed to have been driven by an interplay of external forcing and climate system internal variability. While the hemispheric signal
A volcanically triggered regime shift in the subpolar North Atlantic Ocean as a possible origin of the Little Ice Age
Abstract. Among the climatological events of the last millennium, the Northern Hemisphere Medieval Climate Anomaly succeeded by the Little Ice Age are of exceptional importance. The origin of these
Last phase of the Little Ice Age forced by volcanic eruptions
During the first half of the nineteenth century, several large tropical volcanic eruptions occurred within less than three decades. The global climate effects of the 1815 Tambora eruption have been
Explosive volcanism as a key driver of the late Paleozoic ice age
Atmospheric CO2 exerts a robust and well-documented control on Earth’s climate, but the timing of glaciation during the late Paleozoic Ice Age (LPIA; ca. 360–260 Ma) is inconsistent with pCO2
Baffin Island snow extent sensitivity: Insights from a regional climate model
Recent modeling efforts suggest that the Little Ice Age (LIA) onset could be explained by a series of four large decadally‐spaced volcanic eruptions. At that time, glaciers on Baffin Island advanced

TLDR
The Medieval period is found to display warmth that matches or exceeds that of the past decade in some regions, but which falls well below recent levels globally, and the Little Ice Age is marked by a tendency for La Niña–like conditions in the tropical Pacific.

TLDR
A 21st-century global warming projection far exceeds the natural variability of the past 1000 years and is greater than the best estimate of global temperature change for the last interglacial.
