Swiss Climate Scientists Doubt 1.5°C Target of Paris Agreement

Growing Skepticism Among Swiss Climate Experts
A recent survey of over 80 climate scientists in Switzerland reveals a significant shift in their expectations regarding the Paris Agreement's goal of limiting global warming to 1.5°C. Approximately 95% of respondents believe that this target is unrealistic, with an average projection of a 2.5°C increase by the year 2100. This skepticism is underscored by the alarming trend of rising global temperatures, which have already surpassed the 1.5°C threshold, reaching 1.55°C above pre-industrial levels in 2024.
Impacts of Climate Change on Switzerland
Switzerland is particularly vulnerable to climate change, experiencing warming at twice the global average rate. Projections indicate that local temperatures could rise by 4-4.5°C by the century's end, leading to severe consequences such as the disappearance of over 90% of Swiss glaciers. This would disrupt river flows and threaten water supplies for agriculture, hydropower, and households. Furthermore, cities like Zurich and Geneva could see summer temperatures exceed 40°C, with heatwaves becoming increasingly frequent.
Criticism of Current Climate Policies
Despite the urgency of the situation, independent assessments have deemed Switzerland's climate policies as "insufficient," highlighting a gap between ambition and action. Critics, including NGOs, have expressed disappointment with the Swiss government's emissions targets for 2035, arguing that they rely too heavily on offsets rather than implementing substantial domestic reductions. Axel Michaelowa, head of the research group for international climate policy at the University of Zurich, noted that diminishing public pressure and the focus on other crises have hindered stronger climate action.
Official Statements and Responses
UN Secretary-General António Guterres has echoed these concerns, stating that global efforts to cap warming at 1.5°C are failing. He emphasized that the world is on an inevitable path to exceed this threshold, which could lead to devastating impacts such as floods and unprecedented heatwaves. Guterres highlighted that current national pledges to reduce emissions are grossly inadequate, with a projected reduction of only 10% by 2035, while a 60% reduction is necessary to have a chance of limiting warming to 1.5°C.
Verbatim Quotes
- “We’ve already passed 1.5°C, and in the current geopolitical situation there’s little hope that the goals set earlier will be pursued,” — Harald Bugmann, Professor of Forest Ecology, ETH Zurich
- “Heatwaves will be more frequent and intense, affecting human health particularly in cities,” — Edouard Davin, Professor at the University of Bern
Conclusion: The Path Forward
The findings from Swiss climate scientists reflect a broader global trend of increasing skepticism regarding the effectiveness of international climate agreements. As the world approaches critical temperature thresholds, the need for more ambitious and immediate action becomes ever more pressing. The upcoming COP30 climate summit in Brazil will serve as a crucial platform for nations to reassess their commitments and strategies in the face of an escalating climate crisis.
