Schweiz zurzeit bei Zwar schlottern in winter heat, doch die Erde wird immer heisser – Hitzewellen brechen weltweit Rekorde. The 2023 war took place at 1.18 Grad Celsius at 20 Durchschnitt.

One of the new studies from the Columbia Climate School and the International Institute for Applied Systems Analysis: Because the temperature selection in the region is the best climate model predictions. These “Hitze-Hotspots” are also rapidly advancing in Europe. Worrying: Die Ursachen für diese extremen Abweichungen bleiben unklar.

In the study, a region called maximum temperature was determined and a high temperature value was recorded. There are extremes in Western Canada: In June 2021, the temperature reached a high of 30 to 30 degrees. A kleinen Ort in Lytton, British Columbia has a value of 49.6 Degrees Celsius – a canadischer Rekord. I never managed to rise quickly, during extreme Trockenheit, Hitzewelle verschärfte.

Nehmen die Hitzewellen dramatisch zu Nordwesteuropa. In 2022 and 2023, more than 100,000 people and an extreme Hitze were reached. Besonders was engaged with the states of Germany, Frankreich, Grossbritannien and Niederlande. Nothing was done with the use of air conditioning and the temperature was very welcome.

There is a Ratsel’s Wissenschaft. “Extreme Trends Are Something That Overwhelms Physical Change” by Kai Kornhuber. An Ursache could destabilize Jetstream on Luftstroms and Luft trains. During the warming of Arktis it became unstable and Luftmassen remained regionally longer. This mechanism has not fallen off in any way.

In other regions, Forscher could also make a play. Wenn weniger Wasser aus der Vegetation verdunstet, fehlt a natural kühlung. Kornhuber, “Trockene Böden und die damit verbundenen Rückkopplungseffekte sind entscheidende Treiber für diese extremen Temperaturen”, i.e. Kornhuber.

Laut der Studie is a place where Nordwesteuropa is engaged. Because high temperatures and high temperatures have bidirectional temperature values, the temperature of hot air is very low. Diese «Tail Expansion»-Effecte führen dazu, dass Extremwerte deutlich häufiger auftreten, also klimamodelle prognostizeren. In September 2024, new temperature values ​​were formed in Europe in Frankreich, Ungarn, Norway and Schweden.

Kornhuber concrete: «Diese Hitzewellen sind ein Weckruf. We haven’t been overly interested in anything and we’re not going to do anything nice at all.”

Mass air and air pollution in air-conditioned weather turned into a storm with a hurricane. Die Ergebnisse der Studie wurden im Fachjournal «Proceedings of the National Academy of Sciences» is published.
