A new peer-reviewed study reveals that the summer of 2023 was the hottest in the past 2,000 years. Researchers used ancient tree rings to determine that the summer not only surpassed modern records but also had no equal since the time of the Roman Empire. The extreme heat was attributed to human-caused climate change. The study highlights significant public health stakes, with wildfires sweeping across the Mediterranean, roads buckling in Texas, and power grids straining in China during this period. The study confirmed that 2023 was the hottest on record in the northern hemisphere.
