Summer 2023 Was Hottest in 2,000 Years in Northern Hemisphere, Study Finds

May 14, 2024, 03:45 PM

A new peer-reviewed study has found that the summer of 2023 was the hottest in the past 2,000 years in the Northern Hemisphere. Researchers used tree rings to compare last year's extreme heat with temperatures over the past two millennia. The study, published in the journal 'Nature,' indicates that the summer of 2023 was almost four degrees warmer than the coldest summer during the same period. This unprecedented heat has been attributed to human-caused climate change. The findings underscore the significant impact of climate change, with last summer marked by deadly heat waves, wildfires across the Mediterranean, buckling roads in Texas, and strained power grids in China.
