The effects of the changed climate

  • Climate change effects all of us – individuals, the economy and society. It increases existing challenges, such as the future of energy supply or the use of resources (e.g. water), and is therefore one of the biggest challenges of our time.
  • Average temperatures in Switzerland have risen by about 1.5° since 1970, double the global trend. The effects are clearly visible:
    • Glaciers are melting visibly and retreating.
    • The ground frozen all year round above 2,400 metres (permafrost) is gradually thawing.
    • This gives rise to increased risks of rock fall, rockslide and landslide as well as avalanches and mudflow in the Alps. They can penetrate far into inhabited valleys.
    • Increase in floods also in level country.
  • Two strategies are inseparable when addressing climate change: the adjustment to the unavoidable effects of the changed climate as well as climate protection, in particular the reduction of greenhouse gases.
  • To limit global warming to 2°, global greenhouse gas emissions must be roughly halved by 2050. In particular countries that currently emit high volumes of greenhouse gases must go to huge efforts. Switzerland is also one of these countries.
  • Although Switzerland causes only 0.2% of global emissions, at 7.2 tonnes of greenhouse gas emissions (among other things CO2, methane or nitrous oxide) per head, the country is significantly above the global average of approx. 5.9 tonnes of CO2 equivalent.
