For several centuries in early Medieval times the climate system was relatively unperturbed by natural forcing factors, resulting in a unique period of climate stability. We argue that this represents a reference state for the Common Era, well before anthropogenic forcing became the dominant driver of the climate system.

Dynamical anomalies in terrestrial proxies of North Atlantic climate variability during the last 2 ka

Recent work has provided ample evidence that nonlinear methods of time series analysis potentially allow for detecting periods of anomalous dynamics in paleoclimate proxy records that are otherwise

Late-Holocene: Cooler or warmer?

Early studies on the evolution of glaciers argue that the warm Early Holocene transitioned into a Late-Holocene Neoglacial, with numerous glacial advances due to decreasing solar forcing in the

Little Ice Age climatic erraticism as an analogue for future enhanced hydroclimatic variability across the American Southwest

TLDR
The results coupled with the paleo-record suggests that using the erratic LIA conditions as benchmarks for past hydroclimatic variability can be useful for developing future water-resource management and drought and flood hazard mitigation strategies in the Southwest.

A Century of Reduced ENSO Variability During the Medieval Climate Anomaly

Climate model simulations of El Niño–Southern Oscillation (ENSO) behavior for the last millennium demonstrate interdecadal to centennial changes in ENSO variability that can arise purely from

A Robust Null Hypothesis for the Potential Causes of Megadrought in Western North America

AbstractThe western United States was affected by several megadroughts during the last 1200 years, most prominently during the Medieval Climate Anomaly (MCA; 800 to 1300 CE). A null hypothesis is

A review of past changes in extratropical cyclones in the northern hemisphere and what can be learned for the future

Extratropical cyclones, a major phenomenon of the mid‐latitude atmospheric dynamics, show strong variability over a range of time scales. Future projections hint at an increase of cyclonic intensity

Comment on ‘The Medieval Quiet Period’ – Implications arising from models of solar irradiance

The recent re-evaluation of sunspot data by Clette et al. strongly suggests that the total solar irradiance (TSI) values for the late 20th century were (apart from 1960) not significantly different

Climate in Medieval Time

Many papers have referred to a "Medieval Warm Period." But how well defined is climate in this period, and was it as warm as or warmer than it is today? In their Perspective, [ Bradley et al .][1]

Climate and the Collapse of Maya Civilization

TLDR
A seasonally resolved record of titanium shows that the collapse of Maya civilization in the Terminal Classic Period occurred during an extended regional dry period, punctuated by more intense multiyear droughts centered at approximately 810, 860, and 910 A.D.

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.

Spatial and Temporal Characteristics of Climate in Medieval Times Revisited

Developing accurate reconstructions of past climate regimes and enhancing our understanding of the causal factors that may have contributed to their occurrence is important for a number of reasons;

Robust global ocean cooling trend for the pre-industrial Common Era

Knowledge of natural climate variability is essential to better constrain the uncertainties in projections of twenty-first-century climate change 1–5. The past 2,000 years (2 kyr) have emerged as a

Was there a ‘medieval warm period’, and if so, where and when?

It has frequently been suggested that the period encompassing the ninth to the fourteenth centuries A.D. experienced a climate warmer than that prevailing around the turn of the twentieth century.

Continental-scale temperature variability during the past two millennia

Past global climate changes had strong regional expression. To elucidate their spatio-temporal pattern, we reconstructed past temperatures for seven continental-scale regions during the past one to

Volcanism is a natural climate forcing causing short‐term variations in temperatures. Histories of volcanic eruptions are needed to quantify their role in climate variability and assess human

Northern Hemisphere summer cooling through the Holocene is largely driven by the steady decrease in summer insolation tied to the precession of the equinoxes. However, centennial-scale climate
