2023 Was the Hottest Summer in 2,000 Years, Study Finds

Researchers have found that 2023 was the hottest summer in the Northern Hemisphere in the past 2,000 years, almost 4°C warmer than the coldest summer during the same period.

Although 2023 has been reported as the hottest year on record, the instrumental evidence only reaches back as far as 1850 at best, and most records are limited to certain regions.
