Graphs of yearly global surface temperature compared to the 1991-2020 average from 1850 to 2023, based on data from four different sources: NOAA, NASA, the U.K. Met Office Hadley Center, and Berkeley Earth. Despite small differences among the records from year to year, all show our planet's warming trend, ending with a new record high temperature in 2023.
