Data from the United Nations' World Meteorological Organization released on Thursday indicates that July 2023 will go down as the hottest month ever recorded in human history. The U.N. said July has already had the hottest three-week period ever recorded, the three hottest days on record, and the highest-ever sea-surface temperatures for this time of year. U.N. Secretary-General António Guterres said the data makes it clear that human-driven climate change is to blame for the spike.
