New Delhi: New research published in the journal Nature has found that the summer of 2023 was the hottest in non-tropical regions of the Northern Hemisphere in the last 2,000 years.
The researchers said that although this warming trend cannot be extrapolated on a global scale, the findings demonstrate the "unique nature of current warming", necessitating urgent action to reduce carbon emissions.
Analyzing data from weather-monitoring stations, the researchers found that LAN temperatures in non-tropical regions of the Northern Hemisphere were more than a degree Celsius warmer in the summer of 2023 than the average for instrumented recordings between 1850 and 1900 CE.
To analyze warming patterns over the past 2,000 years, researchers including those from Johannes Gutenberg University, Germany, combined multiple climate models to "reconstruct" Northern Hemisphere summers in non-tropical regions.
The team found that the temperature of the summer of 2023 was 2.2 °C higher than the average temperature before using the instruments for the years 1–1890 CE, making it hotter than the coldest reconstructed summer of 536 CE, when temperatures were less than 1.5 °C before the use of the instruments. Was affected by the explosion, the study said.
