In an attempt to contribute to studies on global climatic change, 110 years of temperature
data for Firenze, Italy, were analysed. Means and trends of annual and monthly temperatures (minimum, maximum and average) were analysed at three different time scales: short (20 years), medium
(36–38 years) and long (55 years). Comparative changes in extreme events viz. frosts in the first and
second parts of the 20th century were also analysed. At short time scales, climatic change was found
in minimum and average temperatures but not in maximum temperatures. At all three time scales, the
annual means of minimum, maximum and average temperatures were significantly warmer in the last
part than in the early part of the 20th century. The monthly mean temperatures showed significant
warming of winter months. Over the last four decades, minimum, maximum and average temperatures had warmed by 0.4, 0.43 and 0.4 ◦C per decade, respectively, and if this trend continues, they
will be warmer by 4 ◦C by the end of the 21st century. The significant decline in days with subzero
temperatures and frosts in the last half of the 20th century, further substantiated the occurrence of
climate change at this site.
