The purpose of this study is to recognise the nature of the climate in historical times (second half of 18th century) in Greenland. Such knowledge is important for validating Greenland temperature reconstructions based on both modelling works and various proxies. The two unique series of old meteorological observations from Greenland we used indicated that temperature in the study period was comparable to that of the early 20th-century Arctic warming but lower than that of the present day.

A comprehensive database of strong winds based on documentary evidence was created for Poland until AD 1600. Three types of documentary sources were used: handwritten and unpublished, published, and “secondary” literature. The database contains detailed information about the occurrence of strong winds (the location/region, time, duration and indexation for intensity, extent and character of damage), as well as the exact textual content of the original weather note.

The present paper upgrades our knowledge of Poland’s climate in the period 1001–1500 using multiproxy data. Four new climate reconstructions have been constructed – three based on dendrochronological data (since the 12th century) and one on documentary evidence (since the 15th century). The results should help improve the knowledge of climate change in Europe, particularly in central Europe.

We present daily temperature and sea level pressure fields for Europe for the severe winter 1788/1789 based on historical meteorological measurements and an analogue reconstruction approach. The resulting reconstruction skilfully reproduces temperature and pressure variations over central and western Europe. We find intense blocking systems over northern Europe and several abrupt, strong cold air outbreaks, demonstrating that quantitative weather reconstruction of past extremes is possible.

This paper presents temperature and pressure measurements from the 37 stations of the late 18th century network of the Societas Meteorologica Palatina, in addition to providing an inventory of the available observations, most of which have been digitised. The quality of the recovered series is relatively good, as demonstrated by two case studies. Early instrumental data such as these will help to explore past climate and weather extremes in Europe in greater detail.

The paper presents the main features of droughts in Poland in the period 996–2015 based on proxy data (documentary and dendrochronological) and instrumental measurements of precipitation. More than 100 droughts were found in documentary sources from the mid-15th century to the end of the 18th century with a maximum in the second halves of the 17th and, particularly, the 18th century. The long-term frequency of droughts in Poland has been stable for the last two or three centuries.

Public granaries served as key infrastructure to improve food security in agrarian societies. Granary data from 15 domains at the Sušice region (southwestern Bohemia) in the period 1789–1849 CE are used here to identify years with bad and good grain harvests, which have been further analysed using documentary data and climatic reconstructions. The data used represent a new source of proxy data for historical–climatological research.

We study the climate effects on mortality, using annual mortality records and meteorological data, in Sweden between 1749 and 1859. It is found that colder winter and spring temperatures increased mortality, while no statistically significant associations were observed between summer or autumn temperatures and mortality, and only weak associations existed with hydroclimate. Further research is needed about which specific diseases caused the mortality increase following cold winters and springs.

Our study collected 63 historical documents on the extreme heat of 1743 from three kinds of historical materials. Using text analysis methods, such as keyword extraction, grading, and classification, we reconstructed the 1743 extreme heat event. This heat event developed cumulatively, and the key areas affected are consistent with those impacted in modern times. Timely cooling and reducing exposure have been limited but necessary means of addressing extreme heat in both ancient and modern times.

The Thirty Years' War (from 1618 to 1648 CE), an armed military conflict in Europe, brought extensive devastation to Europe. The paper analyses annual and seasonal temperature, precipitation, and drought patterns, as well as severe weather extremes, based particularly on documentary data, during this event in central Europe to demonstrate their broad impacts on human society and human responses in coincidence with weather and climate during this period of hardship.

This comprehensive inventory of quantitative documentary evidence related to climate extending back to 1400 CE promotes the first ever global perspective on documentary climate records. It lays the foundation for incorporating documentary evidence from archives of societies into global-scale climate reconstructions, complementing (early) instrumental measurements and natural climate proxies. Documentary records are particularly relevant in seasons and regions poorly covered by natural proxies.

This study examines whether the 1600 Huaynaputina volcano eruption triggered persistent cooling in the North Atlantic. It compares previous paleoclimate simulations with new climate reconstructions from natural proxies and historical documents and finds that the reconstructions are consistent with, but do not support, an eruption trigger for persistent cooling. The study also analyzes societal impacts of climatic change in ca. 1600 and the use of historical observations in model–data comparison.

The East Asian winter monsoon causes orographic snowfall over the windward side of the Japanese islands (facing the Sea of Japan and the northwesterly winter monsoon flow) and negative temperature anomalies around Japan. In this study, we reconstruct the outbreak of the winter monsoon around Japan for the winter from the 1840s to the early 1850s by using daily weather information recorded in old Japanese diaries and early daily instrumental temperature data.

Qualitative evidence contained within historical sources provides an important record of climate variability for periods prior to the onset of systematic meteorological data collection. Before such evidence can be used for climate reconstructions, it needs to be converted to a quantitative format. A common approach is the generation of ordinal-scale climate indices. This review, written by members of the PAGES CRIAS working group, provides a global synthesis of the use of the index approach.

There are controversies about whether poetry can be used as one of the evidence sources for past climate changes. We tried to discuss the reliability and validity of phenological records from poems of the Tang and Song dynasties (618–1279 CE) by analyzing their certainties and uncertainties. A standardized processing method for phenological records from poems is introduced. We hope that this study can provide a reference for the extraction and application of phenological records from poems.

Previous studies related to historical droughts in the Czech Lands showed that the summers of 1531–1540 could represent the driest summer decade of the past 500 years. To confirm this hypothesis, documentary data from central Europe were collected and presented for individual summers and complemented by maps of precipitation and drought distribution to document corresponding weather patterns and their various impacts. The main droughts occurred in 1532, 1534–1536, 1538, and particularly in 1540.

Here we describe the unique nature of droughts over semi-arid central Namibia (southern Africa) between 1850 and 1920. We establish temporal shifts in the influence and impact that historical droughts had on society and the environment during this period. The paper demonstrates and argues that human experience and the associated reporting of drought events depend strongly on social, environmental, spatial, and societal developmental situations and perspectives.

Using reconstructed extreme drought/flood chronologies and grain harvest series derived from historical documents, it is found that the frequency of reporting of extreme droughts in any subregion of eastern China was significantly associated with lower reconstructed harvests during 801–1910. The association was weak during the warm epoch of 920–1300 but strong during the cold epoch of 1310–1880, which indicates that a warm climate might weaken the impact of extreme drought on poor harvests.

The paper analyses a weather diary of the Reverend Šimon Hausner from Buchlovice in south-east Moravia, Czech Republic, in the 1803–1831 period. From daily weather records, series of numbers of precipitation days, cloudiness, strong winds, fogs, and thunderstorms were created. These records were further used to interpret weighted temperature and precipitation indices. Records of Šimon Hausner represent an important contribution to the study of climate fluctuations on the central European scale.

The climate of Granada (southern Spain) during the first third of the 18th century is reconstructed. Results suggest that climatic conditions were similar to those of the first decades of the 20th century, when the global warming signal was of less importance than today. In addition, the paper presents the instrumental data taken in Granada in 1729, probably the first instrumental meteorological data recorded in Spain. Some extreme events, such as the cold wave of winter 1729, are studied.

We investigated the decadal variations of extreme droughts and floods in North China using a 17-site seasonal precipitation reconstruction from a unique historical archive. Then, the link of extreme droughts and floods with ENSO episodes and large volcanic eruptions was discussed. This study helps us understand whether the recent extreme events observed by instruments exceed the natural variability at a regional scale, which may be useful for adaptation to extremes and disasters in the future.

We reconstructed the multi-proxy precipitation field for China over the past 500 years, which includes three leading modes (a monopole, a dipole, and a triple) of precipitation variability. The dipole mode may be controlled by the El Niño–Southern Oscillation variability. Such reconstruction is an essential source of information to document the climate variability over decadal to centennial timescales and can be used to assess the ability of climate models to simulate past climate change.

The paper deals with climatic and human impacts of the strong Tambora (Indonesia) volcanic eruption in April 1815 over the Czech Lands territory based on analysis of documentary data and instrumental records. While climatic effects were related particularly to summers 1815 and 1816 (1816 is known as "a Year Without Summer"), quite important were societal impacts represented after bad harvest by steep increase in prices and shortages of food.

Short summary
This study aims to determine the nature of the climate in Labrador in historical times (late 18th century), which is crucial to understanding past climate changes in the Arctic and their causes. It is equally important to estimate the range of natural climate variability, which can help in correctly recognizing the causes of present and future climate changes – especially the influence of humans on climate. The analysis shows a significant warming from historical to present times.
This study aims to determine the nature of the climate in Labrador in historical times (late...
