Europe is expected to experience another extremely hot summer, especially in popular tourist destinations like Greece, Croatia, and Italy. The continent has been warming at twice the global average since 1991, with an increase in severe heat waves. Despite the forecast, demand for travel to Europe remains high. Cities like Athens are implementing measures to protect residents and tourists from extreme heat, including the appointment of a chief heat officer and the creation of cooling centers. Travel advisers are adjusting itineraries to accommodate the heat, and a start-up in the United States is offering high heat protection insurance for travelers. Some tourists are opting for cooler destinations like Norway, Slovenia, and Sweden to escape the intense summer heat in Europe.
