Thanks to the great longitudinal extension of the peninsula and the mostly mountainous internal conformation, the climate of Italy is highly diverse. In most of the inland northern and central regions, the climate ranges from humid subtropical to humid continental and oceanic. In particular, the climate of the Po valley geographical region is mostly continental, with harsh winters and hot summers.[86][87]
The coastal areas of Liguria, Tuscany and most of the South generally fit the Mediterranean climate stereotype (Köppen climate classification Csa). Conditions on peninsular coastal areas can be very different from the interior's higher ground and valleys, particularly during the winter months when the higher altitudes tend to be cold, wet, and often snowy. The coastal regions have mild winters and warm and generally dry summers, although lowland valleys can be quite hot in summer. Average winter temperatures vary from 0 °C (32 °F) on the Alps to 12 °C (54 °F) in Sicily, like so the average summer temperatures range from 20 °C (68 °F) to over 30 °C (86 °F).[88]

Italy has been a unitary parliamentary republic since 2 June 1946, when the monarchy was abolished by a constitutional referendum. The President of Italy (Presidente della Repubblica), currently Giorgio Napolitano since 2006, is Italy's head of state. The President is elected for a single seven years mandate by the Parliament of Italy in joint session. Italy has a written democratic constitution, resulting from the work of a Constituent Assembly formed by the representatives of all the anti-fascist forces that contributed to the defeat of Nazi and Fascist forces during the Civil War.[89]
Government
Italy has a parliamentary government based on a proportional voting system. The parliament is perfectly bicameral: the two houses, the Chamber of Deputies (that meets in Palazzo Montecitorio) and the Senate of the Republic (that meets in Palazzo Madama), have the same powers. The Prime Minister, officially President of the Council of Ministers (Presidente del Consiglio dei Ministri), is Italy's head of government. The Prime Minister and the cabinet are appointed by the President of the Republic, but must pass a vote of confidence in Parliament to become in office.
While the office is similar to those in most other parliamentary systems, the Italian prime minister has less authority than some of his counterparts. The prime minister is not authorized to request the dissolution of Parliament or dismiss ministers (that are exclusive prerogatives of the President of the Republic) and must receive a vote of approval from the Council of Ministers—which holds effective executive power—to execute most political activities.
