2023 was hottest year in 2,000 years, study shows

A study published in Nature reveals that 2023 was the hottest year in the Northern Hemisphere in at least 2,000 years. Land temperatures were 2.2 degrees Celsius higher than the average between 1-1890. This surpasses the Paris agreement's goal of limiting global temperature rise to 1.5-2 degrees Celsius. The study warns of significant ecological shifts and more severe heatwaves unless urgent action is taken.
