The map at the top of the page portrays international temperature level anomalies for July 2023. High sea surface area temperatures contributed to Julys record warmth. The map shows especially warm ocean temperature levels in the eastern tropical Pacific, proof of the El Niño that started developing in May 2023. Phenomena such as El Niño or La Niña, which warm or cool the tropical Pacific Ocean, can contribute a small quantity of year-to-year irregularity in international temperature levels.” One of the factors this record is concerning is that the impacts of El Niño on worldwide temperatures normally have a several month lag and are felt in the winter season and spring,” said Schmidt.
Elements Driving the Trend
The warmer-than-usual July continues a long-lasting pattern of warming, driven primarily by human-caused greenhouse gas emissions. July 2023 was 0.24 ° C (0.43 ° F) warmer than any previous July in NASAs record. And according to GISS temperature anomaly data, the top-five hottest Julys since 1880 have actually all occurred in the past five years.
Severe heat contributed to devastating wildfires and blistering heat waves in the Northern Hemisphere. “These modifications that were seeing in worldwide temperature levels are being shown in genuine heat extremes that people are experiencing in your area,” Schmidt stated. “We can say with some confidence now that the heat waves we are seeing in North Africa, the Middle East, the U.S. Southwest, China, and southern Europe are being directly affected by the fact that the entire world is warming.”
Information Analysis and Oceanic Factors
The GISS group assembles its temperature analysis from surface area air temperature level information from tens of thousands of metrological stations and sea surface area temperature level information gotten by ship- and buoy-based instruments. This raw information is examined using approaches that account for the diverse spacing of temperature level stations around the globe and for urban heating results that could alter the estimations.
High sea surface area temperature levels contributed to Julys record heat. The map reveals particularly warm ocean temperature levels in the eastern tropical Pacific, proof of the El Niño that started developing in May 2023. Phenomena such as El Niño or La Niña, which warm or cool the tropical Pacific Ocean, can contribute a percentage of year-to-year irregularity in global temperatures. These contributions are not usually felt when El Niño starts developing during the Northern Hemispheres summer season.
Prepared For El Niño Impact
” One of the reasons this record is concerning is that the results of El Niño on international temperature levels typically have a numerous month lag and are felt in the winter season and spring,” stated Schmidt. “Even though we have an El Niño establishing now, the record warmth we are seeing is not yet associated to that in a substantial method. We anticipate to see the most significant impacts of the developing El Niño in February, March, and April 2024.”

July 2023 marked the hottest month ever tape-recorded, constant with a decades-long warming pattern. Human-caused emissions and high sea surface temperature levels are significant factors. The progressing El Niños impact is anticipated in early 2024.
Earth in July 2023 was 1.18 ° C( 2.12 ° F) warmer than the average for the month, and warmer than any other month in the 143-year record.
According to an analysis by scientists at NASAs Goddard Institute for Space Studies (GISS), July 2023 was hotter than any other month in the international temperature level record.
” This July was massively warmer than any previous July and any previous month on record, which goes back to 1880,” said GISS Director Gavin Schmidt. “This continues the long-term pattern in dramatic warming that we have seen over the previous 4 decades.”
Temperature Anomalies and Impacts
The map at the top of the page portrays international temperature level anomalies for July 2023. It demonstrates how much warmer or cooler the Earth was compared to the baseline average from 1951 to 1980. Note that the deepest reds are at least 4 ° Celsius (7 ° Fahrenheit) above the month-to-month mean.
Parts of South America, North Africa, North America, and the Antarctic Peninsula were knowledgeable and especially hot temperature level anomalies around 4 ° C. However it was not unusually warm everywhere. Parts of the U.S. Midwest and northern Europe saw closer to typical temperature levels. In general, July 2023 was 1.18 ° C( 2.12 ° F) warmer than the average July in between 1951 and 1980.
