According to the latest analyses, the annual mean temperature in Austria up to the year 2023 has risen by 2.9 °C since pre-industrial times (1850–1900). The LOESS filter is a statistical method that is already widely used internationally for describing temperature trends. SOCRATES is a robust area-wide data foundation that combines high-resolution spatial information with long-term temperature measurements from Austrian stations going back as far as 1781.

The authors Barbara Chimani, Roland Koch, Anna-Maria Tilg, Manfred Ganekind, Daniel Günther, Anna Rohrböck, Vanessa Seitner, Marion Greilinger, Marc Olefs show in an analysis by GeoSphere Austria that air temperature in Austria has warmed by 2.9 °C since pre-industrial times (1851–1900) up to the year 2023. That is 0.9 °C more than the previously communicated value of 2.0 °C [1] (difference between the mean values for the internationally used 30-year reference period 1991–2020 and the pre-industrial period 1850–1900). The new, higher value is based on the LOESS filter, which is recognised in the specialist community and is significantly better suited to capturing the actual non-linear dynamics of warming both in Austria and globally.
