2023's Summer Was the Hottest in 2000 Years, Study Reveals

Researchers used tree ring data to determine that last summer's temperatures exceeded historical climate variations by nearly a whole degree Fahrenheit.

Scientists from the University of Cambridge and Johannes Gutenberg University Mainz conducted the study.
Tree rings were analyzed to reconstruct temperature records spanning two millennia.
The summer of 2023 was found to be 2.07°C warmer than the average summer from 1850-1900.
El Niño conditions amplified the greenhouse gas-induced warming.
The study emphasizes the urgent need to reduce greenhouse gas emissions to prevent future extreme heat events.
