NASA Reports July 22 as the Hottest Day Ever Recorded on Earth

On July 22, 2024, Earth experienced its hottest day on record, as revealed by a NASA analysis of global daily temperatures. This extreme heat was not isolated, with July 21 and 23 also surpassing the previous daily record from July 2023. These unprecedented temperatures are a result of a long-term warming trend primarily caused by human activities, such as the emission of greenhouse gases. NASA plays a crucial role in monitoring Earth's climate, utilizing an extensive array of Earth-observing satellites and over six decades of data to provide valuable insights.

NASA Administrator Bill Nelson commented on the situation, stating, "In a year that has been the hottest on record to date, these past two weeks have been particularly brutal. NASA's extensive Earth observation capabilities allow us to analyze these changes and help local communities prepare, adapt, and stay safe. We are proud to support the Biden-Harris Administration's efforts to protect communities from extreme heat."

These findings are based on data 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. These systems integrate millions of observations from land, sea, air, and satellites into atmospheric models. The GEOS-FP provides rapid, near-real-time data, while MERRA-2 delivers high-quality, comprehensive climate reanalysis. Both models are managed by NASA's Global Modeling and Assimilation Office (GMAO) at the Goddard Space Flight Center in Greenbelt, Maryland.
