Meanwhile, weather anomalies continue to accumulate records in this 2023. In addition to the hottest day ever, the month of June has never had such high average temperatures. According to data from ERA5, the European system of last generation of climatic data reanalysis, the month that has just ended was 1.46°C warmer than the average of the pre-industrial period (by convention, the second half of the 800), 0.16°C above the previous record of the same month of 2019. With the addition of 6 months of the year, 2023 has a good chance of becoming the hottest year in history with a thermal anomaly of 1.37°C (ERA5 median estimate).
