Southern Hemisphere temperature trend in association with greenhouse gases, El Niño Southern Oscillation, and Antarctic Oscillation
In this study, the trend of mean seasonal and annual temperatures of the calculated based on the HadCRUT5 and NASA-GISS data networks, for the period 1901–2021 and 1951–2021. In order to determine the possible effects on temperature, man, or nature, the relationship with CO2 concentration, GHG (gree...
