Alarming IPCC report – Switzerland is not immune to the apocalyptic climate future

The Swiss are at risk of experiencing more heat waves, heavy rainfall and drought, according to the report published Monday by UN climate experts (IPCC).

Switzerland will not escape this development. It is likely to experience more heat waves, heavy rainfall and drought. "Affecting agriculture and ecosystems, these will increase in frequency and intensity in western central Europe, and therefore also in Switzerland, as global warming increases," says Sonia Seneviratne , professor at ETHZ and a coordinating lead author of the report, in charge of the chapter on weather and climate extremes. Some changes, such as rising sea levels or melting ice caps, are already irreversible for hundreds or thousands of years, says Gian-Kasper Plattner. According to the IPCC report, the retreat of glaciers will also continue for decades, even if global temperatures stabilize. Faced with this apocalyptic future, calls for action are increasing. "Stabilizing the climate will require a strong, rapid and sustainable reduction in greenhouse gas emissions, to achieve carbon neutrality", insists Panmao Zhai, co-chairman of the group of experts who developed this first part of the IPCC assessment.

Switzerland will commit to effective climate protection on a global scale at COP 26, Simonetta Sommaruga said in a tweet on Monday. "The IPCC confirms what the ministers of the affected countries describe to me," she wrote after the publication of the expert group's report.

“The report shows that atmospheric CO2 concentrations in 2019 were 47% higher than at the start of the industrial era and globally higher than at any time in the past two million years,” said said Gian-Kasper Plattner of the Swiss Federal Institute for Forest, Snow and Landscape Research (WSL) and a lead author of the IPCC report.

The global surface temperature between 2011 and 2020 was on average about 1.1 degrees Celsius warmer than in pre-industrial times (1850 to 1900). The frequency and intensity of heat waves and extreme precipitation events have increased since 1950.

According to the IPCC, the main cause of these developments is human-induced climate change. “It is extremely unlikely that some of the recently observed heat waves could have occurred without human influence,” says Sonia Seneviratne, ETHZ professor and a coordinating lead author of the report, in charge of the chapter on weather extremes and climatic.

Global temperatures will continue to rise until the middle of the century. The magnitude of the increase will depend on new issues. And Erich Fischer, another lead author of the report, also from ETHZ, states that "global warming cannot yet be limited to below 1.6 degrees Celsius with more than 50% probability, and very likely to below 2 degrees, only if carbon dioxide emissions decline rapidly in the coming years and are reduced to net zero by 2050”.
