Major heat wave identification with data from 1979 to 2023.
This figure shows the HWMId of the top five heat waves identified for each grid point on land within the European (10°W-40°E, 35–70°N) and the U.S. (70–125°W, 30–50°N) domains. The maps were created using the PlateCarree projection from the Cartopy Python package. Additional details for creating the figure can be found in the study’s minimal data set (see S1 File).
Fig 2.
Maximum HWMId for 1979–2023 heat waves.
This figure shows the maximum HWMId, i.e., the HWMId for the grid point with the highest HWMId, for each year for Europe (a) and the U.S. (b). The red bars highlight the identified top five heat waves for the respective domain. The U.S. 2015 heat wave is excluded due to insufficient spatial extent and the 1980 one due to the limited availability of stock market data.

Aggregated results: Environmental grade portfolios.
This figure presents an aggregated view of statistically significant stock price reactions, categorized according to environmental grade portfolios. The delineation covers all identified heat waves and EWs and is segmented into the whole sample, Europe, and the U.S. Statistically significant negative CAARs are listed as negative stock price reactions. Statistically significant positive CAARs are listed as positive stock price reactions.
