Climate change knows no borders

Nina Knittel is a climate researcher and warns of the dangers of climate change.

Climate change is a global phenomenon and its effects are felt worldwide, but they are unevenly distributed. The impacts of climate change are particularly severe around the equator and in the global south.

Droughts, storms, and hail lead to crop failures, floods destroy production facilities and transport infrastructure, heat reduces human performance and rising sea levels threaten coastal habitats. All of these impacts reduce economic output. This affects directly impacted sectors such as agriculture, as well as the production of a wide range of other goods and tourism.

Moreover, in an interconnected world, these local impacts of climate change are transmitted not only to neighbouring countries, but also to distant countries through various channels.

Climate change impacts are transmitted along international supply chains through a country's foreign trade. The profitability and returns on capital flows and assets held abroad may be reduced in the short term or devalued in the long term as a result of climate damage. Climate change also plays a role in exacerbating existing conflicts, which can increase migration pressures.

Austria’s emissions rose in 2025: University of Graz researchers analyse the causes

The Environment Agency Austria has today published the figures for the country’s greenhouse gas emissions in 2025. While emissions fell sharply year on year from 2022 to 2024, they rose again by just under 0.7 per cent in 2025. Researchers at the University of Graz have analysed how much of this increase was due to structural changes in the economy and how much was attributable to external factors over which there is little control. “In 2025, the colder winter compared with 2024 increased emissions by 0.81 per cent, while the weak economy reduced them by 0.38 per cent. If we factor out these influences, we find an underlying increase of 0.26 per cent compared with the previous year,” reports economist Karl Steininger. “This clearly means that Austria is not on track to meet its climate targets, which require a substantial reduction in emissions by 2030.”

Electrifying: Researchers film the first moments on the way from light to electricity

Physicists at the University of Graz (Austria), in collaboration with colleagues from Marburg University and Forschungszentrum Jülich (Germany), have achieved a scientific breakthrough. For the first time, the generation of electrical energy from light has been filmed and described theoretically. This work is of far-reaching significance, not least for optimising sustainable energy production from photovoltaics. This is because it provides fundamental building blocks for understanding the physical processes that take place, for example, in organic solar cells. The paper was published in the journal Physical Review X, one of the world’s most prestigious physics journals.
