Short summary
Short summary
The paper provides an updated analysis of Poland's climate, focusing on the 16th century using a multiproxy approach (documentary evidence and dendrochronological data). Newly gathered historical sources and dendrochronological data helped reconstruct five updated mean air temperature series: decadal winter and summer means from documentary evidence, and annual means for winter and late winter–early spring derived from dendrochronological data.

We test nine reconstructions of Europe’s hot summer of 1807, using weather records, reanalyses, machine-learning (ML), and data assimilation. Most approaches match observed temperature and pressure well. Approaches based on physics of atmospheric flow capture weather patterns well, while ML approaches better reflect station records. Ingestion of accurate records from new regions improves the reconstructions markedly. In all, the approaches provide new insights to pre-industrial extreme weather.

The article presents: (i) a description of a newly discovered series of meteorological measurements (air temperature, atmospheric precipitation and pressure, humidity, wind direction and force) made in Wrocław (SW Poland) in 1773–81, and (ii) a comprehensive analysis of air temperature. This unique series, quality-controlled and verified against the nearest series of data (Prague and Berlin), extends the regular temperature series for Wrocław back to 1773 (it having previously begun at 1791).

Short summary
The currently observed climate changes are most intense in the Arctic region. This study utilized some of the oldest existing meteorological measurement series in this region. Atmospheric pressure and anemological conditions were analysed and then compared with contemporary measurements. This showed that the weakest low and strongest high systems occur in the same months. Prevailing wind directions have also remained unchanged, while the northerly wind carries less frigid air than in the past.

This study presents and analyses a newly discovered unique series of meteorological measurements from Greenland, covering the period 1806–1813. This record, the longest instrumental dataset from the Arctic before 1840, provides valuable information for improving knowledge about the climate of that period. The analysis shows that it was one of the coldest intervals in the past two millennia. Intense volcanic activity and low solar activity are proposed as the main reasons for this cold period.

A comprehensive database of strong winds up until AD 1600 was created based on documentary evidence for the area within the modern-day borders of Poland. Three types of documentary sources were used: handwritten and unpublished, published, and “secondary” literature. The database contains detailed information about occurrences of strong wind (the location, time, duration and indexation for intensity, extent and character of damage) and the exact textual content of the original weather note.

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.

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.

Short summary
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.
The purpose of this study is to recognise the nature of the climate in historical times (second...
