Our atmosphere is no longer the same: since September 2016, the background concentration of CO2 in the Azores atmosphere has always been above 400 ppm(v). The results of recent forecasts of various climate models, indicating an increase in air temperature and a decrease in precipitation amount, are also clear in relation to the increase in extreme events in the Azores region. For example, and in the most pessimistic scenario of radiative forcing, it is estimated by the end of 2100 that the length of drought periods will increase by almost 5 days, the events of heavy precipitation by more than 1 day and tropical nights by more than 100 days. These results may be explained by the intensification of the North Atlantic subtropical anticyclone in the Azores region, especially west of the British Isles. This work presents the trends of air temperature and precipitation based on the reanalysis of the ERA5 project, as well as the projections and changes for the end of the century; projections for some climatic extremes were also analyzed and variations for the end of the century were estimated with reference to the most recent period.
