Surface air temperature changes December-February 1900-1935 estimated as the difference between the simple 11yr means for the periods 1895-1905 and 1930-1940. Longitudes and latitudes are indicated along the axis of the diagram.
The period 1900-1935 is generally in Europe recognised as a period
of rapid warming after the end of the Little Ice Age. The winter conditions,
however, suggest that for this season it was especially northern and northwestern
Europe that was affected by winter warming, while most regions around the Mediterranean and in southeastern Europe actually experienced a development
towards colder winters. Especially regions north of the Black Sea show clear cooling
during this period.
