September 2022 tied with 2021 as the globe’s fifth-warmest September in the 143-year NOAA record. The year-to-date (January-September) global surface temperature was the sixth warmest on record. According to NCEI’s Global Annual Temperature Outlook, there is a greater than 99% chance that 2022 will rank among the 10-warmest years on record but less than 5% chance that it will rank among the top five.
