ISTAT has also arrived in Italy to combat skepticism about climate change. Or, more specifically, its report "Temperature and precipitation of capital cities in the years 1971-2021," which was released yesterday. Many unambiguous data emerge from the Institute's report's folds. Temperature extremes indices increased for the majority of provincial capitals in the most recent year studied, 2021. Summer days are on average 120 and tropical nights are 44 (up +4 days and +6 nights from the 2006-2015 average). The highest values of the average annual temperature of regional capitals were recorded in the decade 2011-2021 (average of the period 15.8 ° C) during the 40-year study. In 2014, temperatures reached 16°C (+1.5°C on CLINO 1971-2000). Furthermore, when 109 provincial capitals are considered, total precipitation is decreasing, with an average of 746 mm (-119.4 mm from 2006 to 2015).
