Europe and Turkey Confront Accelerating Heatwave Threats

Economists warn that increasingly frequent heatwaves are turning from temporary weather events into a structural macro‑economic risk for Europe. ING Global Macro Research head Carsten Brzeski says the continent could face cumulative GDP losses of $131 billion in Germany alone between 2026‑2030, with similar damages projected for France, Italy and Spain. The heat stress reduces labor productivity, raises energy and cooling costs, strains water supplies and can disrupt transport and supply chains, adding to inflationary pressures.

A joint study by Istanbul Technical University, Samsun University and the University of Missouri analysed 60‑100‑year records from 15 stations in Istanbul, Ankara and Izmir. It found statistically significant increases in heatwave frequency at 11 stations, with rises of 0.14‑0.78 events per decade, while cold‑wave occurrences declined. Annual average temperatures are also climbing 0.20‑0.50 °C per decade, extending extreme heat into autumn and lengthening longer‑duration events.

Both analyses highlight that the intensifying heatwave trend is already affecting public health, labor markets and economic output across the region.
