The Study of Air Temperature in the Last Decade in the Bucharest Metropolitan Area

Multiple paleoclimatic studies indicate that the Earth has warmed significantly since the end of the 19th century. The mean  temperature of the Earth's surface is rising unnaturally and frighteningly fast, having a large impact and threatening the very near future of human civilization. This paper presents an analysis of the variability of air temperature in the Bucharest metropolitan area in the decade 2011-2020, related to the  1901-2000 period in the context of the global warming. The research includes the study of the mean annual and monthly temperature, the absolute maximum and minimum temperature, the frequency of the thermal character in the cold season and in the hot season and the frequency of days with characteristic temperatures. The 2011-2020 decade was the hottest one since the beginning of meteorological measurements. Related to the 1901-2000- reference period, the air temperature increased by 1.6°C, from 11.1°C to 12.7°C, the mean of  the 10 years. The year 2020 was the hottest year, marking the end of the hottest decade since the meteorological measurements were made, the mean annual temperature being 13.5°C,  by 2.4°C higher than the mean of the 1901-2010 reference period.
