Satellite view of the Iberian Peninsula on 11 May 2023 and 11 May 2023. These images, acquired by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite, show where green vegetation in May 2022 turned brown by May 2023. The sparse rainfall further parched soils that were already unusually dry in 2022. According to a recent report by Copernicus Climate Change Services, soil moisture across all of Europe in 2022 was the second lowest in the past 50 years. Unseasonable heat exacerbated the prolonged drought. On 26 April 2023, hot air from North Africa swept over southern Spain and pushed the temperature at the Córdoba airport to 38.8°C (101.8°F), the highest April temperature recorded in continental Spain.
