[1] 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… Expand

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.

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 signalExpand
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. Expand
Little Ice Age climate and oceanic conditions of the Ross Sea, Antarctica from a coastal ice core record
Increasing paleoclimatic evidence suggests that the Little Ice Age (LIA) was a global climate change event. Understanding the forcings and associated climate system feedbacks of the LIA is madeExpand
Sea surface temperature and sea ice variability in the subpolar North Atlantic from explosive volcanism of the late thirteenth century
[1] In this study, we use IP25 and alkenone biomarker proxies to document the subdecadal variations of sea ice and sea surface temperature in the subpolar North Atlantic induced by the decadallyExpand
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 theseExpand
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 beenExpand
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 pCO2Expand
Was Common Era glacier expansion in the Arctic Atlantic region triggered by unforced atmospheric cooling
Abstract The timing and causes of Common Era (CE) glacier growth in the Arctic Atlantic region remain elusive. There is mounting evidence of advances that predate the Little Ice Age (1250–1850 CE);Expand
Paradoxical cold conditions during the medieval climate anomaly in the Western Arctic
TLDR
A new moraine chronology based on 36Cl surface exposure dating from Lyngmarksbræen glacier, West Greenland is presented, attributing this expansion to multi-decadal summer cooling likely driven by volcanic and/or solar forcing, and associated regional sea-ice feedbacks. Expand

Global Signatures and Dynamical Origins of the Little Ice Age and Medieval Climate Anomaly
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. Expand

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. Expand
