UPDATE: June 2023 was the warmest June globally since modern recordkeeping began in 1880, measuring at 1.07°C (1.93°F) above @nasa's 1951-1980 baseline average. The 5 hottest Junes have all occurred since 2019: https://data.giss.nasa.gov/gistemp/
The third image is the same graph, but on @ipcc's 1850-1900 temperature baseline. Here, June 2023 was also the warmest June globally since 1880, measuring at 1.29°C (2.32°F) above this baseline average. The 5 hottest Junes have all occurred since 2019.
#FYI, @nasa uses its baseline because @nws uses a 30-year period to define "normal," or average, temperature. NASA started tracking temperatures in 1980, and the most recent 30-year period at that time was 1951-1980.
@ipcc uses its baseline to represent preindustrial temperature. It's the earliest period of near-global observations of surface temperature. This allows for a comparison of current temperatures with a period before significant human-caused climate change.
Image Descriptions:
1. Global map of average June 2023 temperature changes, with relative warming in portions of Canada and Asia, western Europe, and in the Antarctic Peninsula. There was some relative cooling in parts of India, Pakistan, western Australia, and the U.S. Overall, most places were warmer than normal.
2. A plot showing an upward trend in average relative June global temperatures since 1880, using NASA’s 1951-1980 baseline.
3. A plot showing an upward trend in average relative June global temperatures since 1880. This one is on the IPCC’s preindustrial temperature baseline (1850-1900).
