The map at the top of this post illustrates international temperature level abnormalities forJune,July, andAugust2023It demonstrates how much warmer or coolerEarth was compared to the standard average from1951 to1980Note that the inmost reds are at least 4 ° C( 7 ° F) above the mean.
This brand-new record comes as extraordinary heat swept throughout much of the world, worsening fatal wildfires inCanada andHawaii, and searing heat waves inSouthAmerica,Japan,Europe, and the U.S., while most likely adding to extreme rains in Italy, Greece, and Central Europe.
Consequences and Causes of the Temperature Surge
“Summer 2023’s record-setting temperatures aren’t just a set of numbers—they result in dire real-world consequences. From sweltering temperatures in Arizona and across the country, to wildfires across Canada, and extreme flooding in Europe and Asia, extreme weather is threatening lives and livelihoods around the world,” stated NASA Administrator BillNelson “The impacts of climate change are a threat to our planet and future generations, threats that NASA and the Biden-Harris Administration are tackling head-on.”
NASA assembles its temperature level record, referred to as GISTEMP, from surface area air temperature level information gotten by 10s of countless meteorological stations, in addition to sea surface area temperature level information from ship- and buoy-based instruments. This raw information is evaluated utilizing approaches that represent the different spacing of temperature level stations around the world and for metropolitan heating results that might alter the computations.
The analysis computes temperature level abnormalities instead of outright temperature level. A temperature level abnormality demonstrates how far the temperature level has actually left from the 1951 to 1980 base average.
Role of El Ni ño in Temperature Elevations
“Exceptionally high sea surface temperatures, fueled in part by the return of El Niño, were largely responsible for the summer’s record warmth,” stated Josh Willis, environment researcher and oceanographer at NASA’s Jet Propulsion Laboratory in Southern California.
El Ni ño is a natural environment phenomenon defined by warmer than typical sea surface area temperature levels (and greater water level) in the main and eastern tropical Pacific Ocean.
1880– 2023
The record-setting summertime of 2023 continues a long-lasting pattern of warming.

ElNi ño’sBroaderEffects andImplications
“With background warming and marine heat waves that have been creeping up on us for decades, this El Niño shot us over the hump for setting all kinds of records,”Willis stated.“The heat waves that we experience now are longer, they’re hotter, and they’re more punishing. The atmosphere can also hold more water now, and when it’s hot and humid, it’s even harder for the human body to regulate its temperature.”
Willis and other researchers anticipate to see the greatest effects ofElNi ño inFebruary,March, andApril2024El(************************************************************************************************************************************************************************************************* )ño is related to the weakening of easterly trade winds and the motion of warm water from the western Pacific towards the western coast of theAmericas The phenomenon can have extensive results, frequently bringing cooler, wetter conditions to the U.S. Southwest and dry spell to nations in the western Pacific, such as Indonesia and Australia.
“Unfortunately, climate change is happening. Things that we said would come to pass are coming to pass,” stated Gavin Schmidt, environment researcher and director of GISS. “And it will get worse if we continue to emit carbon dioxide and other greenhouse gases into our atmosphere.”
