Changes in the global mean air temperature over land since 1980

Changes in frequency of record-breaking land surface temperature over Earth's since 1980 are assessed here using six different gridded datasets comprising monthly mean air and weather station data retrieved from Global Historical Climatology Network NOAA Summary the Day. The 2010–2020 decade was warmest history modern measurements for more than one third Earth surface, i.e., Europe, United States, southern Africa, northern Siberia most Australia, according to four datasets. Since 1980, new high/maximum records have been observed parts eastern Asia North America. 2020 year recorded, while 2010 hottest America (≈34% territory). Approximately 60% recorded a maximum annual after 2010. In terms comparison, ERA5 came closest stations regarding ever at various locations Berkeley indicated highest correlations total number events.
