Last year’s intense northern hemisphere summer heat made 2023 the warmest in some 2,000 years, new research suggests.
Scientists have declared last year’s June-August as the warmest since record-keeping began in the 1940s.
New article published in the journal Nature suggests the 2023 was hottest in 2,000 years. The study was based on the analysis of tree rings across nine northern sites.
Last year’s summer season temperatures on lands between 30 and 90 degrees north latitude reached 2.07 degrees Celsius higher than pre-industrial averages, the study claims.
Based on tree ring data, the summer months in 2023 were on average 2.2 C warmer than the estimated average temperature across the years 1 to 1890.
