Dog-days, cold periods, grape-harvests (France, 15-19th centuries).

The climate history can be based on several kinds of data. In the present paper, French records of grape-harvest dates in Burgundy from 1370 to 1890 were used for evaluate the climates at these various period of time. These results reveal that temperatures as high as those reached in the 1990s have occur-red several times in Burgundy since 1370. Correlations between temperatures and historic data are presented.
