Globally, the hottest June, July, August, and now September since modern instrumental surface temperature records started being kept in the 19th century occurred this year. Zeke Hausfather, a climate researcher associated with the ecomodernist Breakthrough Institute, noted that the global average temperature for September reported by the Japanese Reanalysis (JRA-55) of global temperature trends "beat the prior monthly record by over 0.5C, and was around 1.8C warmer than preindustrial levels."
