In order to preserve vital natural resources for future generations, the Confederation provides incentives for innovative and sustainable products and informs the population about environmentally sustainable behaviour. The focus is on reducing greenhouse gas emissions, which are the main cause of the climate-warming greenhouse effect. Federal Department of Foreign Affairs FDFA It pursues an environmental policy geared towards resource-saving, climate-friendly and sustainable technologies and solutions. That is more than twice the rise in the average global temperature of around 1°C (as of 2019). For example, everyone knows what a summer's day feels like. Lakes, mountains and clean air are inextricably associated with Switzerland's quality of life. The long temperature data series from Basel since 1755 (Figure 1) illustrates this situation very clearly: Natural fluctuations dominate the temperature up to the beginning of the 20th century. A variety of measures have been taken in Switzerland to help keep the rise in average global temperatures below 1.5°C by 2050. Which clothes will I need in the mountains during summer? The Alpine climate in the country is also highly appealing to a huge number of people. That is why Switzerland's public sector is increasingly requiring environmentally friendly and resource-saving products in its procurement processes. These show the future climate development for Switzerland and are based on the current state of scientific research. Switzerland's The average winter precipitation over the last 150 years has risen in most regions in Switzerland (with the exception of the southern Alps and large areas of Grisons). Switzerland's built environment continues to grow. Reconvalescence in the Alpine climate, in particular from Tuberculosis, is another important branch of tourism in the 19th and early 20th centuries for example in Davos, Graubünden.

However, certain changes that have taken place since industrialisation can only be explained in terms of the increase in greenhouse gases. Tourism is also a crucial sector due to the abundance of a number of natural attractions that draw people from all over the world. Since 1980, however, the trend is positive, and hours of sunshine are similar today to what they were at the beginning of the 20th century.The observed increase of 2.1°C is a figure that is difficult for people to conceptualise. The steep temperature rise in the last few decades, on the other hand, is a consequence of the increasing greenhouse gas emissions (climate change).The effects of climate change are evidenced in numerous weather parameters - with the most obvious being temperature. So, temperature indicators are already showing significant changes: Summer days and hot days (maximum temperature equal to or higher than 25°C/30°C respectively) have seen a huge increase, while ice and frost days (maximum temperature lower than 0°C/minimum temperature lower than 0°C) have dropped substantially. The climate in Switzerland is characterised by large natural fluctuations. The Swiss construction project of the century – linking northern and southern Europe It has also adopted an action plan to reduce the risk and promote the sustainable use of plant protection products, which are among the most widely used pesticides. This is indispensable to adapt and evaluate the risks and opportunities associated with climate change.Weather observations and measurements from around the world indicate that climate is characterised by large fluctuations. Whether drought is on the increase is at present not yet conclusive.Together with research partners, MeteoSwiss has been developing national Climate Change Scenarios for more than 10 years. Until the beginning of the 20th century, these fluctuations were primarily due to natural causes. To safeguard this natural heritage the Federal Council and the people of Switzerland have adopted a series of concrete measures in recent years. So Summer is best time to go to Switzerland for cultural tourism. Tourism begins with British mountaineers climbing the main peaks of the Bernese Alps in the early 19th century (Jungfrau 1811, Finsteraarhorn 1812). Together with ongoing renaturation programmes, these measures are designed to further improve the environmental condition of Switzerland's Air pollutant emissions have been considerably reduced in recent decades as a result of measures taken by the Confederation, cantons and municipalities. The Federal Department of Foreign Affairs presents Nowadays, primarily in the low-lying areas, there are significantly fewer days with snowfall, and smaller amounts of new snow falling than 30 to 40 years ago. In order to eliminate micropollutants, including residues from medicines, cosmetics and pesticides, the Federal Council has decided to add an additional treatment stage to the largest of the approximately 800 wastewater treatment plants in Switzerland over the next 20 years.
