Short summary
Short summary
Narrative historical records of wine production in Central Europe date back to 1200. A study of taxes paid to authorities in the French-Luxembourg Moselle region, Germany, and the Swiss Plateau over the last few centuries shows that wine yields provide indirect indications of summer temperatures when the impact of heavy frosts is taken into account. This enables climate reconstructions based on tree rings to be refined and confirmed. Occasionally, poor harvests gave rise to witch hunts.

Short summary
Short summary
We study the climatic signal, with a focus on volcanic-induced shocks, in two long annual records of wine production quantity (spanning 1444–1786) from present-day Luxembourg, close to the northern limit of viticulture in Europe. Highly significant wine production declines are found during years following major volcanic events. Furthermore, warmer and drier climate conditions favoured wine production, with spring and summer conditions being the most important ones.

Short summary
Short summary
We study the climate signal in long harvest series from across Europe between the 16th and 18th centuries. The climate–harvest yield relationship is found to be relatively weak but regionally consistent and similar in strength and sign to modern climate–harvest yield relationships. The strongest climate–harvest yield patterns are a significant summer soil moisture signal in Sweden, a winter temperature and precipitation signal in Switzerland, and spring temperature signals in Spain.

Short summary
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.
