July 22, 2024, was confirmed as the hottest day on record, based on NASA’s global daily temperature data analysis. This day, along with July 21 and 23, surpassed the previous record set in July 2023, highlighting a concerning trend of rising global temperatures attributed to human-induced greenhouse gas emissions. NASA Administrator Bill Nelson emphasized the severity of these conditions and the agency’s role in monitoring and addressing climate change impacts.
NASA’s findings were derived from the Modern-Era Retrospective analysis for Research and Applications, Version 2 (MERRA-2), and the Goddard Earth Observing System Forward Processing (GEOS-FP) systems, which aggregate data from various global observation instruments. These systems, operated by NASA’s Global Modeling and Assimilation Office, provide both rapid weather data and in-depth climate reanalysis, ensuring comprehensive monitoring of Earth’s changing climate.
The record-setting temperatures are part of a broader trend of increasing global heat, corroborated by independent analyses, such as the European Union’s Copernicus Earth Observation Programme. NASA’s ongoing data collection and analysis efforts aim to enhance understanding and preparedness for extreme heat events, contributing to the broader efforts to combat and adapt to climate change.
