July 2023 hottest month ever measured

July was the hottest month on record, according to data from the EU’s Copernicus climate change service. The service only has data since 1940, but Copernicus Deputy Director Samantha Burgess said Tuesday, referring to calculations by the Intergovernmental Panel on Climate Change: „It hasn’t been this warm in at least 120,000 years.“ Climate researchers can reconstruct historical climate from tree rings, air bubbles in glaciers and corals, among other things.
