In this article, we present research results on the air temperature changes on the Labrador coast at the end of the 18th century (1771–1787). This important climatic variable was studied on the basis of valuable instrumental meteorological observations made by Moravian missionaries. The data were taken from meteorological registers available in thr...
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 Three types of documentary sources were used: handwritten and unpublished, published, and “secondary” literature.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 indexa...

A review of many studies published since the late 1920s reveals that the main driving mechanisms responsible for the Early Twentieth Century Arctic Warming (ETCAW) are not fully recognized. The main obstacle seems to be our limited knowledge about the climate of this period and some forcings. A deeper knowledge based on greater spatial and temporal...
