Hunga eruption changes the atmosphere: researchers show effects

Less than a week ago, lava began to bubble up from the earth again in Iceland. In Sicily, Mount Etna does not come to rest. The eruption of a volcano can have massive consequences for a region. But its breath can also reach far beyond. During the eruption of Hunga in January 2022, the largest volcanic event of the 21st century to date, an unprecedented amount of water vapour was released into the upper atmosphere. Researchers from the Wegener Center at the University of Graz, in collaboration with colleagues from the USA, have investigated the changes in these high layers of air. They found an exceptional cooling of the stratosphere. This has far-reaching effects on the atmosphere and the climate. The study has recently been published in Communications Earth & Environment.

Extreme heat affects child mortality in Africa

It is a sustainable development goal of the United Nations to reduce child mortality to 25 deaths per 1000 livebirths in children younger than five years by 2030. The mortality rate is influenced by various factors. The role played by malnutrition and diseases such as HIV or malaria is well known. However, little is known about the connection with very high temperatures. An international study involving the University of Graz now shows that the influence of extreme heat on the risk of death in children under the age of five in Africa varies depending on age group, climate region and season. Each country must therefore take its own preventive measures tailored to the respective conditions and target groups.

Greenhouse gas emissions decline in Austria: researchers reveal causes

Good news: greenhouse gas emissions in Austria fell by 6.4 percent in 2023, as announced by the Federal Ministry for Climate Action and the Environment Agency at a press conference today. Researchers at the University of Graz have analysed the causes for this reduction. The main reasons are changes in production processes and the behaviour of the population. They resulted in a 5.6 percent drop in emissions. A further drop of 0.8 percent was due to lower economic activity and the warm winter.
