July 22 was the hottest day on record on Earth

Jul 29. () –

July 22, 2024 was the hottest day on record worldwide, according to a NASA analysis from global daily temperature data.

July 21 and 23 of this year also surpassed the previous daily record, established in July 2023.

These record temperatures are part of a long-term warming trend driven by human activitiesmainly the emission of greenhouse gases, according to the US space agency.

“In a year that has been the hottest on record, these past two weeks have been particularly brutal,” he said. it’s a statement NASA Administrator Bill Nelson.

This preliminary finding comes from analyses of data from the Modern-Era Retrospective Analysis for Research and Applications, Version 2 (MERRA-2) and Goddard Earth Observing System Forward Processing (GEOS-FP) systems, which combine millions of global observations from instruments on land, sea, air and satellites using atmospheric models. GEOS-FP provides fast, near real-time weather data, while the MERRA-2 climate reanalysis takes longer but ensures the use of the highest quality observations, according to NASA. These models are run by the Global Modeling and Assimilation Office (GMAO) at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.

In the chart above, MERRA-2 global mean daily temperature values ​​for the years 1980-2022 are shown in white, values ​​for the year 2023 are shown in pink, and values ​​from 2024 through June are shown in red. Daily global temperature values ​​from July 1 to July 23, 2024 from GEOS-FP are shown in purple.

The results They coincide with an independent analysis by the European Union’s Copernicus Earth Observation ProgrammeAlthough the analyses show small differences, they show broad agreement regarding the change in temperature over time and the hottest days.

The latest daily temperature records follow 13 consecutive months of record-breaking monthly temperatures, according to scientists at NASA’s Goddard Institute for Space Studies in New York.

Their analysis was based on the GISTEMP record, which uses only instrumental surface data and provides a longer-term view of changes in global temperatures at monthly and annual resolutions dating back to the late 19th century.
